Maryland Death Cluster Due To H3N2 Drift Variant

 

virus-influenza-h1n1-2010-1.jpgRecombinomics Commentary 22:50
March 27, 2012 The CDC has released five sets of H3N2 from recent collections in Maryland.  All five sequences were generated directly from the clinical samples, strongly suggesting that all five were linked to the recent death cluster. 

Three of the samples (A/Maryland/04/2012, A/Maryland/05/2012, A/Maryland/06/2012) were from March 5 collections, the date of death for two of the siblings.  The other two, A/Maryland/08/2012 and A/Maryland/09/2012, were from collections on February 21 and February 20 respectively.  Although the ages and gender of the index case and three children involved in the Maryland death cluster have been cited in media reports, the CDC withheld the age and gender for all five sequences. 

Thus, the assignment of each of the five samples was not possible from the public data released by the CDC.  However, all five H3 sequences were virtually identical and related to the drift variant, A/Brisbane/299/2011, which has S199A, as noted for prior sequences designated as low reactors by the CDC. 

A reassortant of A/Brisbane/299/2011 (designated A/Brisbane/299/2011 X-215) has been generated as a potential H3N2 vaccine target because it is a variant that produces a low reaction when tested against the current vaccine, which is directed against A/Perth/16/2009.


Thus, the sequence data confirmed that the Maryland cluster were from a drift variant and were unlikely to react well with the current vaccine, in contrast to the CDC comments and internet rumor.

Flu Infections And MRSA Deaths In Maryland

mrsa-pneumonia.jpg

 

 

Sad news out of Maryland, and a reminder of how devastating MRSA, methicillin-resistant Staphylococcus aureus, can be when it combines with flu infection. According to the Maryland Department of Health and Mental Hygiene, the Washington Post and ProMED, five members of a family have fallen ill and three have died from MRSA pneumonia that took hold in lungs inflamed by flu infection.

The dead are Ruth Blake, 81, and her children Lowell, 58, and Vanessa, 56. Another child, Elaine, also fell ill and was hospitalized, and Ruth Blake’s sister has been hospitalized also. They had all contracted one of the seasonal flu strains circulating this year: H3N2. According to the Post, Ruth Blake was vaccinated against flu this season; her children were not. The assumption is that both flu and MRSA spread from the mother to the children.

 From the Post:

Calvert health officials said in a statement Wednesday that the cases were isolated to a single family and that “there are currently no other affected individuals.” Local health-care providers, they said, are not reporting any significant increase in patients with flulike symptoms.

David Rogers, the county’s health officer, said health officials suspect that Blake also had the flu and then suffered a serious lung infection that turned into pneumonia.

“In older people, that can often be fatal,” he said.

Blake had a flu shot, he said. None of the others were vaccinated.

What’s unusual, he said, is that the infection spread from the mother to three children, probably at her bedside. Most likely, the mother’s coughing spread the virulent organisms into the air, and her caregivers, two of whom also had the flu, breathed them in and became infected, he said. (Byline: Annys Shin and Lena H. Sun)

MRSA pneumonia is fast-acting and lethal; it is often called “necrotizing pneumonia” for the way it simply kills lung tissue. Exactly why it has that effect is still disputed — MRSA has so many cellular toxins at its disposal that there could be a number of culprits — but there is no dispute that it is a very serious disease.

MRSA post-flu pneumonia isn’t well-understood because it has been a concern only recently. The first cases to alert the United States this might be a problem were in Baltimore in the flu season of 2003-04. The four patients were all seen at Johns Hopkins University Medical Center, and physicians there wrote the cases up afterward. Over two months, there was a 31-year-old woman who was in the hospital for four weeks; MRSA ate holes in her lung, the largest of which was 1 by 1.5 inches. Two other women, 20 and 33 years old, were each hospitalized for three months. The 20-year-old’s heart stopped, and her blood clotting grew so disordered that doctors had to amputate one leg below her knee; the 33-year-old lost both lower legs. The fourth patient was a 52-year-old man, a two-pack-a-day smoker, who died.

Other reports came into the Centers for Disease Control and Prevention over the course of that flu season. When the CDC counted up the following summer, there had been 15 cases of severe MRSA pneumonia in 9 states. Four of them died. CDC personnel wrote another article warning of the dangers of MRSA and flu two years later, after clusters of cases in Louisiana and Georgia during the 2006-07 flu season. They said: “Secondary S. aureus pneumonia is a potentially catastrophic complication of influenza… MRSA [community-acquired pneumonia] often affects young, otherwise healthy persons and can be rapidly fatal.”

Pneumonia that follows on flu is a seriously under-appreciated danger of flu infection: An analysis from 2010 points out that, in 2007, there were 457 deaths from flu in the US and 52,847 deaths from post-flu pneumonia. There is no reliable way to protect yourself against MRSA, since there is no vaccine, and the bacterium can live on the skin undetected for an unpredictable period of time. Hypothetically, if you prevent flu infection you lessen the likelihood of this pneumonia occurring — but as the mother’s case illustrates, flu vaccine doesn’t confer perfect protection, especially not in the elderly whose immune systems are not robust enough to begin with.

It’s a very sad story, and another illustration of how perilous and destructive MRSA can be.

H3 "Strain" In Maryland Death Cluster Remains Unclear

calvert-county-deaths.jpg

 

Recombinomics Commentary 18:45
March 7, 2012

"State health officials say today that lab tests confirm that two of the members of a Calvert County family who died early this week of severe respiratory illness had Influenza H3, a strain of the flu that has been going around this season".

The above comments confirm the Recombinomics commentary published this morning on the H3 sero-type of the HA from the fatal Calvert County, Maryland cluster.  However it is unlikely to be the “strain” of flu that has been going around this season. 

Recombinomics called the Calvert County Health Department as well as the Maryland Department of Health and Mental Hygiene, and the US CDC to get a clarification on the testing that led to the report that the influenza A was seasonal flu, since the CDC has reported an explosion of H3N2 low reactors in the week 7 and week 8 FluView reports.  The antigen characterization data indicated an new H3 had replaced the H3N2 strain that had been circulating earlier this season.

The CDC did not comment on this explosion and therefore it was unclear if the low reactors were a drift variant of the current seasonal H3N2 vaccine target, Perth/16, or were widespread H3N2v, which would also generate a low reactor result.

Moreover, the CDC PCR test distributed to state labs can identify H3N2v under ideal conditions, but most confirmed H3N2v cases gave negative, inconclusive, or seasonal H3 results, and H3N2v was confirmed by CDC sequencing.

The cluster in Maryland was determined to be H3 by the Maryland state lab, which was used for this morning’s announcement by Calvert County.  Media at the Maryland state lab suggested I e-mail the specific testing questions, and also noted that the best source of information would be the CDC, who had already been asked via cell phone and e-mail about testing and the relationship between the H3 result generated by the Maryland state lab and the low reactors reported by the CDC, which may be H3N2v.

As of this commentary, neither agency has responded to the e-mailed questions, and the relationship between the H3 in the death cluster, the low reactors reported by the CDC, and H3N2v remains unclear, but the likelihood that the H3 “strain” in the Maryland death cluster matches the seasonal H3N2 dominant in the US in 2011 and early 2012 is extremely small.

Maryland Death Cluster H3 Confirmed

Recombinomics Commentary 16:30
March 7, 2012

"Initial testing of two of four family members in Lusby, three of whom have died, suggests that that the serious lung infection suffered by all four was a complication of seasonal flu. A fourth family member remains hospitalized at Washington Hospital Center and is improving".

The above comments from the latest update from the Calvert County Health Department website indicate the Calvert County, Maryland death cluster was linked to seasonal influenza.  A call to the health department indicates the state lab obtained an H3 serotype.  However, it remains unclear if the H3 is Perth/16-like and recognized by the current H3N2 vaccine or a "low reactor” as described in the week 8 FluView.

Moreover, it remains unclear if this is a Perth/16 variant or an H3N2v which gives and H3 positive on the CDC PCR test.  H3N2v has D225G, which is associated with patients coughing up blood.

More detail on the PCR testing and sequences from the CDC would be useful

Flu-like Death Cluster In Calvert County Maryland

"The first patient, an 83-year-old woman, became sick on Feb. 23. Three of her children, a son and two daughters all in their 50s, arrived on Feb. 28 to take care of her.

The mother died on March 1. One daughter, 56, and her son, 58, both died on Monday while a third daughter, 51, remains at Wash Hospital Center in critical condition".

The above comments describe a death cluster in Calvert County, Maryland.  Anecdotal reports also describe a fifth victim, the funeral director who had contact with the bodies.  These reports also indicate fatal cases were coughing up blood and the funeral director was hospitalized with breathing difficulties.

More information on testing would be useful.

Three Recent H5N1 Cases In Dhaka Bengladesh

avian-flu.jpg

 

Recombinomics Commentary 19:00
March 5, 2012

Detection of three new human infections with the deadly H5NI strain of bird flu in a week has set alarm bells ringing as scientists have found evidence of the virus in the live-bird market in crowded Dhaka.

The above comments describe three confirmed H5N1 cases in wet market workers in Dhaka, Bangladesh.  The first case has been WHO confirmed and has recovered, but the three 2012 cases has doubled the number of H5N1 confirmed cases in Bangladesh.  This significant up tick is almost certainly due to clade 2.3.2.1 which has now expanded its geographic spread and was confirmed in crows in India earlier this season.  New sub-clade migrate into India and Bangladesh each season, which are closely related to each other.

The first human clade 2.3.2 was described in media reports in the spring of 2008 when a culler (soldier) developed symptoms and was H5 PCR confirmed.  However, South Korea denied the culler was infected with clade 2.3.2 because prior human infections in China were clade 2.3.4.  Moreover, South Korea used the failure to isolate the H5 virus as an excuse for not filing a report.  However, the sequence had V223I and M230I, which were in the Gharbya cluster and fatal clade 2.3.2.1 cases were subsequently reported in China, including the recent case from Shenzhen who had no reported poultry contact (but had wild bird exposure).

The appearance of clade 2.3.2 in south Asia raised concerns of additional human cases, and the three confirmed cases in Bangladesh are likely confirmation of the realization of such concerns.

Why does the medical world feared H3N2 S-OTR?

h3n2-h1n1.jpg

 

 

 

 

 

 

 

 

 

World Press and Vietnam again caused a stir and organizational control disease prevention (CDC) confirmed three more American young people in Iowa mutate flu virus infects a new A (H3N2) derived from pig . As from January 8.2011, the CDC has recorded 12 cases scattered in five northeastern states of the United States. The samples after the tests to detect genetic decoding in the variable new strains of genetic reassortment between H3N2 is circulating in pigs in the United States with M genes of H1N1 pandemic strain in 2009, is S-OTR called H3N2 (swine-origin H3N2 triple reassortant).

Why does the medical world feared H3N2 S-OTR?

Influenza A viruses, including subtypes (subtypes) based on a combination of two proteins, hemagglutinin (H) and Neuraminidase (N). . There are 16 H antigens and nine antigen N.  In nature, each H and N antigens are often distributed in a certain species of animals.  Currently only three H antigen subtypes (H1, H2, H3) and two subtypes N antigens (N1, N2) is regularly circulated in humans. The other subtypes found mostly in animals. Wild birds are natural hosts of the virus.

The most important characteristics of the virus is likely to change frequently antigenic structure through the phenomenon of mutation and genetic recombination.  Meanwhile, strains "new" would escape recognition by the immune system, easily cause major outbreaks and high mortality risk to the community without resistance. History has proven each pandemics were caused by a new virus appears to mutate.

Back at the North American case, which flu strains are circulating in pigs rarely causes human disease.  Since 2005, only 35 cases reported in the United States, but production levels have increased in 2011.  When different strains co-infection in a host body, the genetic material can exchange and create a new strain variables.

At the conference Fourth European Influenza held in Malta (May 9.2011), a scientific discovery has been global shocked Dr. Ron Fouchier and colleagues at Erasmus Medical Center Rotterdam (Netherlands) announced . In the laboratory, they have successfully tested the mutant strains caused by H5N1 virus introduced directly into the respiratory tract to cause infection experiment repeated on civet.  With only five through ten mutant virus experimental phase, they have gained new H5N1 strain can spread easily through the airways from civet to others. Biologically, this means the ability to spread from person - people with respiratory!

A similar result was also published later by Ruben O. Donis and colleagues from the CDC Atlanta, USA mutagenic when carrying sialic acid receptors on antigen H and N antigens on the H5N1 virus.

H5N1 threat there

H5N1 bird flu virus circulating in migratory birds, infected poultry, but no symptoms (especially in species of aquatic birds).  Due to different antigenic structure should only pathogenic H5N1 virus for some people with close contact (slaughter poultry diseases) and not be able to spread from person to person. Diseases caused by H5N1 in humans begins with the outbreak in 1997 in Hong Kong. Up to date 08/02/2012, the world's total was 584 cases with 345 deaths (59%). In Vietnam, since the first cases detected in the hospital as soon 11/01/2004 tropical disease, now has a total of 121 cases (the third highest in the world after Indonesia and Egypt), 61 deaths ( 50%).  After nearly two years absence from the H5N1 Swine Flu, the health ministry announced two deaths from H5N1 in January 1.2012 in Kien Giang and Soc Trang.  Ministry of Agriculture and Rural Development is published on the H5N1 poultry in the provinces of Thanh Hoa, Ha Nam, Hai Duong, Quang Tri, Soc Trang and Kien Giang.

As translated in poultry, the risk of H5N1 infection when exposed and not protected very high and the cases will continue to happen ...

Worst case scenario and how to deal

When infected people continue to have variable influenza virus strains circulating in human capital (such as avian influenza H5N1, H3N2 swine flu ...), viral conditions regular exercise over how to penetrate the human body, the ability to turn adaptive genetic change will have many opportunities to occur and to a certain time, a new varieties with the ability to spread from person - who will appear (this time in natural conditions, repeat the process "of make " was successful in the lab)!

Imagine a new pandemic scenario for the appearance of a human influenza virus can mutate damage the strength of the H5N1 (mortality 50%) combined with the ability to spread from person - person via the respiratory tract of H1N1 each 2009 pandemic (worldwide spread in just three months)!

Before a flu pandemic threat is happening in the future, the medical community should be prepared for questions: when would appear? Any complications? Responding to like? ...

First of all, have solved the bird flu. Spread to humans by blocking the implementation of biosecurity measures in animal husbandry, food processing line clean. Implementation of effective vaccination for poultry and humans. Monitoring, detection and early treatment of cases to be dispersed in the community.

Hopefully, mankind continues to win the race for survival with competing microbial world, which took place millions of years and continues increasingly fierce.

Another H5N1 Bali Indonesia Fatality

alert-1.jpg

 

Recombinomics Commentary 16:00
February 21, 2012

Denpasar Bird flu virus still a threat, a boy with the initials WM (12) died of the H5N1 virus is. WM is the origin of Badung, Bali
"Based on the PCR, he's positive, "he said. case of death of this child is the fifth death from bird flu virus that occurred in Bali.

The above translation describes lab confirmation of another fatal H5N1 case (12M) in Bali.  Earlier, sequences from a Bali cluster of three were released.  The sequence from the mother was a recombined sequence derived from the sequences from her children.  The sequences had multiple receptor binding domain changes, which may have been present in the Indonesian clade 2.1 H5N1 used in the Ron Fouchier transmission experiments, which began with three changes and acquired two additional changes.  The five changes in two genes represented previously reported polymorphisms, which were used in ferret transmission experiments.  The death of all 40 exposed ferrets has raised concerns that a lethal transmitting H5N1 could emerge in the near term.

The recent clusters in Indonesia and Egypt have raised concerns that the withholding of the details in the Fouchier and Kawaoka experiments continues to be hazardous to the world’s health.

 

Absence of Poultry Contact for H5N1 Bali Indonesia Fatality
Recombinomics Commentary 18:00
February 21, 2012

Of the interrogation Sanglah party, according to Ken, could not be ascertained whether the WM had contact with poultry. "The family is still denying that the victims had contact with poultry. We are therefore of bird flu team is digging deeper than where the victim of a virus," explains Ken. But from the VCR in Sanglah examination showed that the victim was positive for influenza WM birds. Due to the bad condition when taken to the hospital Sanglah, WM can only last for five hours and finally died at 03.00 pm, Tuesday (21/2) yesterday.

The above translation, describing the recent fatal case near Bali, Indonesia notes the lack of a reported bird contact.  This case follows a cluster of three with disease onset dates which supported human to human transmission, which was also supported by the recombinant H5N1 sequence from the mother (39M) of the first two cases (5F, 10M).
These lab confirmed cases increase concerns that the H5N1 in Indonesia is evolving toward efficient transmission.  Clade 2.1 was the source for the H5N1 used by Ron Fouchier.  After 10 passages in ferrets the virus had 5 chnages in 2 genes and 4 of the 5 changes have been found in published sequences.

This alarming development has been overshadowed by concerns of bioterrorism and an NSABB recommendation to withhold details.  This recommendation has been rejected by scientisis meeting in Geneva last week, who were given the details on the tranmssion studies.

The relative ease in the creation of a transmitting H5N1 or an H5 reassortant highlights the lack of preparation for a transmitting H5N1.
The current vaccine program has largely stockpiled older isolates, and although newer targets have been selected. Pandemic preparedness lags, and the only clade 2.1 vaccine target is the 2005 isolate from the initial Tangerang cluster.


International Meeting On Controversial Bird Flu Research, H5N1 Wake Up Call

virus-influenza-h1n1-2010-1.jpg

 

Recombinomics Commentary 14:30
Bruce Alberts says that the research shows that it is very easy for lethal bird flu to develop and it should act as a "real wake up call to the world".

He added: "This is likely to happen at some point in the wild because these viruses are mutating very actively in the wild."

Kudos to Science for cutting to the chase on the H5N1 transmission issues.  The two papers are game changes with regard to the understanding of the risk of a natural and evolving H5N1.  Prior “experts” had claimed that H5N1 would never transmit in humans because it is an “avian” virus, and had not jumped to humans, in spite of many opportunities since the outbreaks in Hong Kong in 1997, and rapid expansion in Asia in 2004, and throughout Europe, the Middle East, and Africa in 2006.

However, two different groups using two distinct sub-clades had achieved efficient transmission in a ferret model involving a small number of natural changes, highlighting the near term potential for efficient transmission.

Although the NSABB has the right to request limitations, they have not made a scientifically valid argument.  Instead, public comments have revealed a serious lack of understand of the scientific literature and the abilities of others to reproduce and improve the transmission based on papers published prior to the acceptance of the papers at Nature and Science.

Both groups have published extensively in the past, and media reports describe the overall findings.  The Science paper uses a clade 2.1 isolate from Indonesia with three changes, which was passed in ferrets to select two additional changes.  All five changes in the two genes have been described previously, although all five have not been reported in the same isolate, although published sequences include four of the five is a single isolate.  The Nature paper uses a different sub-clade (2.3.4.2) from Vietnam, but only the H5 is used.  It is on an H1N1 background, and the sub-clade and construct have been described previously.

Thus, any serious program targeting an H5 that transmits efficiently in mammals would already have sufficient information to reproduce and improve the censored results, since there is little doubt that transmission is not limited to the two examples described in the Nature and Science papers.

H5N1 however, remains a poor choice as a bioweapon because it can’t be controlled once it has been released, although interest in a transmitting H5N1 will likely increase due to the attention and concerns expressed by the NSABB.

The concerns have also detracted from the game changing result, as noted in the above quote, which is why the papers should be immediately published in full, so a true discussion of the significance of these results can begin, which includes enhanced surveillance and counter measures such as an extensive H5N1 vaccination campaign to protect against a naturally evolving H5N1.

Suspect H5N1 Cluster In East Java Indonesia

Suspect H5N1 Cluster In East Java Indonesia
Recombinomics Commentary 14:30
February 17, 2012

Outbreaks of bird flu again attacked chickens in residential Wahidin Road South, RT 2, RT3 / RW III Petamanan Village, District of South Bugul, Makati City.

At least 80 chickens died suddenly from a week ago. In addition to attacking the chicken, the bird flu outbreak is believed to have infected a number of residents in these settlements. A total of five people are known to suffer from the disease with symptoms of fever, bone pain, and shortness of breath.

As experienced Ponimah (52). Since three days ago, he felt the symptoms of shortness of breath, cough, runny nose, watery eyes, and bone pain.

The above translation describes a suspect H5N1 cluster near Pasuruan, south of Surabaya in East Java, Indonesia.  Addition reports indicate the poultry associated with the suspect cases has tested positive for H5N1.
Symptoms in 5 residents in area raise concerns of increased transmission. 

The report being delayed at Science from the Ron Fouchier lab in the Netherlands used a clade 2.1 sequence from Indonesia to generate a transmissible H5N1 in a ferret model, which maintained its lethality.  After ten passes in ferrets, the transmitting H5N1 had 5 changes in two genes.

Release of five changes in this manuscript is long overdue. 

Vietnam: H5N1 variation (clade 2.3.4) vaccines powerless

Friday, 02/17/2012 22:32

The avian influenza virus was genetically engineered into the new virus is highly virulent, contagious and resistant to vaccines. While Vietnam does not have A/H5N1 flu vaccine on humans

While bird flu continues to spread to many provinces, the deadly virus have been many changes detrimental to the prevention and treatment measures in poultry. More worrying when the death rate from influenza A/H5N1 in humans is 100% of cases are detected.

Resistant virus vaccine

On 17-2, Hoang Van Nam, Director of Animal Health authority (Ministry of Agriculture - Rural Development), said from the beginning of this year has 11 local detection of avian influenza including Thanh Hoa, Quang Tri, Soc Trang, Ha Nam, Hai Duong, Thai Nguyen, Kien Giang, Bac Giang, Ha Tinh and Hai Phong and Quang Nam.

Not yet quarantined poultry still be comfortable buying and selling, slaughtering in Hanoi

There were nearly 20,000 birds, mostly ducks to be destroyed. The bird flu is complicated, spread in all 3 regions. If loose slaughtering operations management, transportation and trade of poultry, the risk of widespread outbreaks is huge.

Risk of spreading bird flu, today (18-2) National Steering Committee for prevention of avian influenza will have an emergency meeting to discuss measures to cope. Meanwhile, Mr. Diep Kinh Tan on 17-2, Deputy Minister of Agriculture - Rural Development, said it had written to the Prime Minister requests the State budget of 13 billion contract to buy 50 million doses of H5N1 vaccine Re-vaccination strains fifth round of 1-2012 for timely enclosure, stamping out.

According to Tan, 2012 is expected to need 327 million doses of vaccine given to poultry, but due to bird flu virus in the northern provinces with the change, the vaccine strain H5N1 Re-5 protection levels households is not high. Meanwhile, in the southern provinces, not bird flu virus is modified to use H5N1 vaccines imported from China, so immediate permission to import 50 million doses.

The risk to humans is very large

According to experts, the bird flu virus may be genetically caused the surveillance becomes more difficult. Department of Animal Health representative said before, there are 3 branches Vietnam H5N1 virus has been detected. A branch in the south, north branch and the branch 2.3.4 7 capable of highly infectious.

However, recently in the northern provinces, discovered a new bird flu virus branch, symbol 2.3.2 branch. More worryingly, had discovered the virus 2.3.2 branch into 2 groups. With a group of old virus, vaccine against bird flu meets only 75%, while the new virus, vaccines are currently using does not work. Therefore, the risk of spreading the virus in poultry and humans is very large. What is more dangerous than professional bodies continue on raising waterfowl flocks, sold in many places but no signs or symptoms but still carry the virus H5N1.

Dr. Nguyen Hong Ha, deputy director of Tropical Diseases Hospital Central, concerned with the weather hot and humid climate are favorable for growing influenza virus. Moreover, with the normal seasonal flu viruses such as influenza B, H1N1, H3N1, H5N1 ... the risk is present, the virus strains combine or mutate to create new influenza virus virulent more dangerous is huge. Currently, flu vaccines are being used in Vietnam is just common flu as influenza A (H3N1, H3N2, H1N1) and there is no vaccine against A/H5N1 flu in humans.
100% mortality rate

According to Dr. Tran Thanh Duong, deputy director of the Department of Preventive Health (MOH), A/H5N1 flu spread from birds, waterfowl infected with influenza A/H5N1 virus to humans is strongly virulent virus, the mortality rate very high. At this point, the rate of death from influenza A/H5N1 in humans is 100% of cases were detected. Two cases were patients who died despite antiviral treatment.

The first Vietnamese influenza A (H3N2) from pigs

first-child-h3n2v.jpg

 This is a two-year-old girl, in Duoc, Long An and is now cured. For years, our country has recorded cases of infection with influenza virus A (H3N2) in humans, also known as regular seasonal flu, while flu patients is derived from pigs.


 Notification by the Department of Preventive Health (MOH), influenza surveillance system key southern countries recorded cases of this flu from 4/2011.  Recently, the test results were standard laboratory form of the World Health Organization confirmed in the U.S..
  This is the first case reported in Vietnam infected with influenza A (H3N2) derived from pigs.  Mild movements and no evidence of transmission from person to person. Từ From May 4/2011 so far not found more cases of new flu strains.

Vietnam H3N2v Swine Flu Case Raises Transparency Concerns

The national flu monitoring system detected this case in April 2011. A two-year-old female baby in Long An province contracted the disease and was treated successfully at the Children’s Hospital No 1. in HCM City. The A/H3N2 flu virus she had originated from pigs.

The test results of the HCMC Pasteur Institute were confirmed on January 10, 2012, by the WHO laboratory at the US Centres for Disease Control and Prevention (CDC).

The above comments provide additional clarity on the dates surrounding the confirmed H3N2v case in Vietnam, but still leave many questions unanswered.  It is likely that this case was initially classified as seasonal H3N2 in 2011.  The H3N2v cluster in Iowa in November led to an alert issued by WHO, largely because the three confirmed cases had no swine exposure.  That alert was followed by a media report in Vietnam that described the US cases and increased surveillance in Vietnam.  Those reports incorrectly described the US H3N2v cases as H3N1.
Last week media reports in Vietnam again issued a warning about H3N2v cases, but only provided detail on the cases in the United States and again described the cases as H3N1, and a follow-up report claimed no H3N2v cases in Vietnam in 2012 (carefully parsed to avoid acknowledgement of the 2011 case).

Today, reports from Vietnam described the above case (age, gender, and location) and the English language reports clearly indicated this was a 2011 case that was confirmed over a month ago by the US CDC.

This raises several important questions, which have not been answered. None of the reports have cited a swine exposure by the confirmed case.  Similarly, the CDC has not released the sequences at GISAID, as was done for the 2011 variant cases in the United States (H3N2v, H1N2v, H1N1v).  Moreover, WHO has not announced the confirmed case, in spite of lab confirmation by a WHO regional center, although it is unclear if the WHO has announced this case at its password protected site.
Thus, a month after confirmation, all of the above questions remain unanswered by public data, although the sequence would clearly distinguish between a linkage to Asian or North American swine lineages.

The lack of transparency by WHO and the CDC continues to increase pandemic concerns.

H3N2v Swine Flu Case Confirmed In Long An Vietnam

As reported by the National Influenza Center - Pasteur Institute of Ho. Ho Chi Minh, influenza surveillance system key southern countries found cases of A/H3N2 flu originated from pigs.

This is a new 2-year-old female patients in Duoc, Long An influenza have been treated at Children's Hospital 1 and then cured. Samples of these patients have been tested in a laboratory at the CDC standard WHO official - the United States and has been confirmed.

Yang said, this is the first case reported in Vietnam A/H3N2 flu originated from pigs. This slight movement of cases and no evidence of transmission from person to person.

The above translation describe the first case (2F) of H3N2v in Vietnam (Duoc, Long An).  In contrast to earlier reports, which described similar cases in the United States, this report describes a PCR confirmed case in the Mekong Delta region in southern Vietnam.

As noted earlier, there are 6 sets of public sequences from H3N2v in swine, isolated in 2010 (A/swine/Binh Duong/03_06/2010, A/swine/Binh Duong/03_08/2010, A/swine/Binh Duong/03_09/2010, A/swine/Binh Duong/03_10/2010, A/swine/Binh Duong/03_13/2010, A/swine/Binh Duong/03_14/2010). All six isolates are closely related and have human H3 and N2 genes, with swine internal genes that are generally more closely related to H3N2v swine sequences in Asia (South Korea and Hong Kong).

However, Hong Kong has released 3 sets of sequences from Guangxi and Hong Kong (A/swine/Guangxi/NS2783/2010, A/swine/Hong Kong/2503/2011, A/swine/Hong Kong/NS2439/2011) , which have similar H3 and N2 human genes surrounding six internal genes from H1N1pdm09. In the United States, all 12 of the H3N2v sequences in humans in 2011 have an H1N1pdm09 M gene. Prior H3N2v cases in the United States have PB1 E618D, which is not in the swine isolates from Vietnam, but is in the new sequences from Hong Kong and China, since E618D is in virtually all H1N1pdm09 PB1 sequences.

The above report does not cite swine contact, so the origin of the infection is far from clear.  H3N2v in Vietnam is readily distinguished from H3N2v in the United States.

Information on the constellation of genes in the case in Vietnam would be useful.

Alert, Bird Flu Virus Mutation, The H5N1 symptoms in Indonesia have changed !!!

H5NI virus or commonly known as bird flu has mutated over the nature of change or development time, this is further strengthened by reports of a number of areas.  Even so, not yet ascertained the impact of the change.
  It is feared the virus could be more dangerous than ever before.  Further research is needed to ensure the fatality rate of the new virus.
  Head of Animal Husbandry and Health of Central Java Province, Semarang District Whitono reveals, some poultry that died of bird flu now has features that are not as usual, ie no black or bluish spots on the comb or body part that is not hairy.
 Meanwhile, Head of Animal Health Animal Husbandry and Animal Health in Central Java, Eko Sutarti revealed, though not sure about the new virus, characteristics of birds that died of bird flu part shifted.
  Usually the birds that died of bird flu are marked with blue or black spots on the comb or body parts that are not covered in fur.  Now the poultry that died suddenly without these spots were found positive for bird flu.
  Of Brebes, Central Java, reportedly, the body's defense system against virus attacks poultry in the region changed when compared with previous years. This is evident from the clinical symptoms found in cases of chicken deaths in the region last week.
 Head of Animal Health and Veterinary Public Health Veterinary Services Bradford, Jhoni Murahman say, around 2003, when he first outbreak of bird flu virus in Bradford, clinical symptoms of bird deaths at that time happened very quickly and in large quantities.  Physical signs in birds that died of bird flu is also very clear, that the body was black, very much saliva, swollen heads and blue crest on the head.

  However, at present, clinical symptoms are not very visible. Poultry deaths tend to be in unison, but one by one.  Body of dead birds as well just turn blue with not a lot of saliva and the head is not swollen.

25 Tail Poultry Sudden Death 
  London continues to increase alertness, following the discovery of 25 birds that died suddenly in some districts during 2012. . However, after checking through the rapid test, avian bird flu was declared negative.
   Bandung, Maria Dewi in Soreang, Sunday (12/02/2012) says, from the beginning of January 2012 to Sunday, it received reports of about 25 birds died suddenly.
  "There have been reports from some districts, namely Cimaung, Rancaekek, Nagreg and Soreang who reported any poultry that died suddenly. But after we checked, it turns out negative bird flu," he explained.
  It is said, if there are reports of dead birds suddenly, direct action by the parties Disnakan spraying disinfectant around the discovery of the dead birds.
 "In particular for this disinfectant we have not been scheduled. But there are reports of each case, we immediately move and do a rapid test. With the rapid test, in 20 minutes can be found out whether the results are positive or negative. In addition, we also do spraying disinfectant," he said .
  Although not yet found a positive poultry bird flu this year, but continue to increase vigilance Disnakan. Moreover, the previous year was found positive poultry bird flu in eight villages. Only when compared to the year 2010, that number has decreased.
  Maria further said, to prevent bird flu cases in the District does not happen again.  Bandung, it will continue to take preventive vaccination of pets, especially birds and the provision of disinfectants.

Japan suffering from worst flu season in 10 years

japan-child-flu.jpg

 

By NOBUYA SAWA / Staff Writer

Face masks are being seen everywhere in Japan at the peak of flu season, as the number of patients is increasing at the fastest pace in 10 years.

The number of patients who sought treatment at medical institutions subject to a survey stood at 42.62 on average in the latest week from Jan. 30 to Feb. 5. That was the highest at this time of the year since 2002.

The total number of flu patients in Japan is estimated to be about 2.11 million.

Starting this month, the number of patients who have contracted different types of flu strains is also increasing.

This influenza season features the spread of a Type A Hong Kong flu for the first time in five seasons. About 90 percent of patients were contracting that type of virus until January. From this month, however, patients that are suffering from a Type B influenza are also increasing in some areas.

“Antibodies that were gained as a result of infection are maintained for certain periods. As time passes, however, their effects wane. As a Type A Hong Kong flu is spreading after a long interval, people may have lost their immunities,” said Hideki Hasegawa, director of the Department of Pathology at National Institute of Infectious Diseases (NIID).

Because of the various types of strains, there is a growing fear that the current flu season will be a long-lasting one.

In the Tokyo metropolitan area, until mid-January, the number of patients was relatively small. In recent weeks, however, it has increased sharply there. In addition, the number of patients has been hovering at high levels in the Tokai and Shikoku regions since early January.

According to an announcement from the NIID, the number of patients per medical institution stood at 35.95 on a national average in the previous week from Jan. 23-29.

In the latest week, however, the figure jumped to 50.94 in Saitama Prefecture, 50.84 in Chiba Prefecture, 45.20 in Tokyo and 48.86 in Kanagawa Prefecture.

In the Kinki region, the corresponding figures were hovering around 40 in the latest week, almost the same as that in the previous week. For example, it stood at 44.81 in Osaka Prefecture and 42.46 in Hyogo Prefecture.

In the previous week, prefectures with the largest numbers of patients per medical institution were Fukui, Kochi and Aichi. In all of the three prefectures, their figures dropped to 64.41, 54.21 and 47.38 respectively in the latest week. However, the figures were still at high levels.

In Chugoku and Kyushu regions, high levels also continued in the latest week with the number of patients at 51.64 in Yamaguchi Prefecture, 55.36 in Miyazaki Prefecture and 45.67 in Oita Prefecture.

The number of flu patients is also increasing in areas affected by the Great East Japan Earthquake. In Iwate Prefecture, the number increased from 45.52 in the previous week to 58.98 in the latest week, the second highest in Japan following Fukui Prefecture.

Fatal Suspect H5N1 Case In Cengkareng Indonesia

 Now, allegations of similar cases are also found in West Jakarta, where a boy aged three years initials RV, a resident of RT 15/07 Cengkarengtimur Village, District Cengkareng , died on Monday (23 / 1) around 06.00 after previous intensive care at Friendship Hospital, East Jakarta.

Regarding the victim's body is covered a coffin and not allowed to open, say Parwathi, it was according to the procedure as a form of anticipation of the hospital for suspected cases of bird flu. Despite the negative results of bird flu, disclosed Parwathi,

The above translation describes the death of a suspect H5N1 case (3M) in Cengkareng, Indonesia, which is adjacent to Tangerang, where another suspect H5N1 case (18M) also died after testing negative for H5N1.  These two cases had bird flu symptoms and were buried in a sealed coffin, which is customary for H5N1 cases.

The failure to detect H5N1 in these two fatal cases in adjacent areas on the west side of Jakarta is in addition to the suspect case in Bekasi, on the east side of Jakarta, as well as the confirmed cluster in North Jakarta, where the second case initially tested negative for H5N1.

These five cases in the Jakarta area raise concerns that H5N1 is being more efficiently transmitted as it evolves away from the sequences being used in the H5N1 PCR test.

Fatal Suspect H5N1 Case In Tangerang Indonesia

Patient suspect bird flu, Rohmat (18), resident of RT 09/03, Ciodeng Village, Village Blooms Jaya, District Panongan, Tangerang regency, died after being treated for five days in critical condition in RSU Tangerang District, on Wednesday.

Previously the patient's condition was critical since it first entered isolation space bird flu," said Public Relations RSU Tangerang Regency Ahmad Muchlis when confirmed on her cell phone. According Muchlis, until now is still not clear whether Rohmat died from bird flu or not. "There is no certainty. But the results of observations in the home environment Rohmat by the Health Department yesterday was negative bird flu," he said. He added that the next will Rohmat shrouded corpse in the mortuary. Chances are, he said, Rohmat not take home to his family home. "The possibility is not taken home, but immediately buried," explained Muchlis.

The above translation describes the death of a suspect H5N1 case (18M) in Tangerang, Indonesia, which is on the northwest side of Jakarta.  The death follows a confirmed H5N1 cluster in North Jakarta, as well as suspect fatal cases in Cengkareng, which is adjacent to Tangerang, as well as Bekasi, which is on the east sided of Jakarta. 

Although the three most recent cases have not been H5N1 confirmed, the second case (5F)  in the North Jakarta cluster tested negative multiple times before H5N1 confirmation at autopsy, raising concerns about the sensitivity of the H5N1 for the bird flu currently circulating in Indonesia.
False negatives in Indonesia are common because patients are tested after the start of Tamiflu treatment, which lowers the RNA level.  Patient who recover continue to test negative and are not reported as confirmed cases, while those who die have increasing H5N1 RNA levels, which eventually test positive.  This testing procedure accounts in part for the high case fatality rate, which ha been near 80% in Indonesia since the first confirmed cases were reported in 2005.

However, at least two the three cases adjacent to Jakarta have tested negative, even though the patients have died with H5N1 symptoms, and have been quickly buried, per protocol for confirmed H5N1 cases.
These recent fatalities and the failure to link the cases to infected poultry, has raised concerns that the H5N1 in Indonesia is being transmitted more efficiently, as seen in the confirmed cluster in North Jakarta as well as the Bali cluster.

Sequences from the Bali cluster included receptor binding domain changes (D187N, A188G, R193M), as well a clear examples of recombination.  Moreover, these chnages are likely to lead to immunological escape.

Release of sequences from the North Jakarta cluster would be useful.

Neighbors Nuntung Dg, also experienced the same event. Fourteen of his chickens, died suddenly.
"One chicken bangkok kasian I die, too. Now live chicks remaining," said Dg Nanring.

Do not want to take risks, a number of teams from the field of Animal Husbandry Takalar immediately took to the field. They took samples of dead chickens and chickens live who are ill to be examined the scene.

"The chickens are infected with virus positive ND (newcastle disease), not the bird flu. ND virus is not contagious to humans, but its spread to other chicken fast enough," explains Head of Livestock Department of Agriculture and Forestry Takalar Ghani Muhammad Ridwan.

He also suggested to conduct spraying disinfectant on the chickens are still alive. Ridwan also said, live chickens infected with ND virus can still be consumed as long as it is cooked to perfection.

"To destroy this virus is rather difficult. Control can only be done by way of vaccination. It is common place, as it related to weather factors. So that affect the health of chickens that are easily infected with ND virus of this disease," he explained.

To obtain more complete results, it also brought some samples to be tested in depth in the laboratory.
