First H5N1 avian influenza and pandemic influenza A/H1N1 appeared together in a community population

Risk associated virus A/H1N1, A/H5N1 is very close to

Wednesday, September 12, 2009 [trans. 12/9/09]

In case of death due to influenza A/H5N1 after eating duck soup more of a young men at Dien Bien on November 30 experts has raised concerns about the ability to match the influenza A/H1N1 virus and influenza A/H5N1 virus are at risk are very close.

"The risk of a combination of influenza virus A/H1N1 and influenza A/H5N1 virus is very close to. Vietnam currently has sufficient condition for this risk becomes reality", Dr. Nguyen Tran Hien, Director of Institute of Hygiene and Epidemiology of central receiving.

Show his outlook given the Institute of Hygiene and Epidemiology Central announced the latest report on the epidemiological investigation in Dien Bien, which is just the latest case of deaths due to H5N1.

Epidemiological investigation showed that: In case of death by eating more duck soup at Dien Bien is positive for influenza A/H5N1 virus. After taking a random sample from their child's case to test the test, the results showed that young cousin's death was due to influenza A/H5N1 influenza A/H1N1 infection.

Continue to check poultry being raised by families of cases of death due to influenza A/H5N1, the results showed: Poultry is also infected with influenza A/H5N1.

"So, the first in Vietnam, the same time, the influenza A/H1N1 and influenza A/H5N1 occurred in a community population, in both human and poultry. Therefore, likely a new strain will come out, the recombinant virus from the second. If this happens, the virus would have spread faster than influenza A/H1N1 virus, while also having a higher pathogenic influenza A/H5N1 virus, "said the sage.

If this risk becomes reality, the health sector will face challenges more heavily. Actually shows that influenza A/H1N1 virus can spread easily in all conditions. Now with influenza A/H5N1, mortality rate in Vietnam as of this moment is 100%!

Currently, the health sector is being implemented to control and closely monitor the disease situation at Dien Bien province in particular, at the same time coordinate with ministries and departments concerned to implement measures to control the back of avian influenza in other localities in the country.

However, in the current situation, this control may not happen as easily as expected. According to a review of the Department of Animal Health (Ministry of Agriculture and Rural Development), now many places have not actively implementing measures to prevent disease, lead to bird flu outbreak started emitted.

[The previous article sounded like it was a combination within one patient. It was not.]

Risk of interactions occurring influenza H1N1 and H5N1 influenza

At regular meetings the National Steering Committee for prevention of influenza pandemic in humans pm 9/12, Associate Professor, Dr. Nguyen Tran Hien, Director of Institute of hygiene and epidemiology of central receiving, translated influenza A/H1N1 further complicated development risk occurs because the interaction between influenza A/H1N1 and influenza A/H5N1 in the community.

According to survey research institute of the Central Hygiene and Epidemiology, cases of death from influenza A/H5N1 in Dien Bien past have discovered a family of patients positive for influenza A/H1N1.

Meanwhile, poultry was raised in the patients were infected bird flu. Dr. Hien said that the two types of this virus live together in one area can lead to the risk of formation of new pathogenic strains stronger.

Therefore, the Institute is conducting close monitoring of the outbreak evolutions in time to cope with bad situations can occur.

Dr. Nguyen Huy Nga, Director of Department of Preventive Health and Environment also said that in Vietnam, the beam of ca influenza A/H1N1 infection has decreased song precautions to patients with pneumonia for most of the cases This admission has positive results for influenza A/H1N1.

Health Ministry warns that all patients with pneumonia should be hospitalized when the PCR test for diagnosis and treatment of influenza A/H1N1 in time in order to minimize mortality.

World Health Organization (WHO) has recommended influenza A/H1N1 vaccine using a secure, among 65 million people worldwide have been vaccinated influenza A/H1N1 vaccine but has not detected any cases of death death. With lots of vaccines in case of Canada react, WHO is continuing investigation to clarify the cause.

The Health Ministry also issued "Guidelines to monitor and flu A/H1N1 replaced on May 27, 2009 Decision No. 1846/QD-BYT to promptly deal with the epidemic in the new situation. /.

Re: Vietnam - First H5N1 avian influenza and pandemic influenza A/H1N1 appeared together in a community population

From what I can gather from these articles. It appears as the most recent H5N1 death case, some of his family members tested postive for H1N1 and they had H5N1 infected chickens. Am I right on this assumption?

Re: Vietnam - First H5N1 avian influenza and pandemic influenza A/H1N1 appeared together in a community population

That is what I am believing. This particular sentence....I believe....is a bad translation:

In case of death by eating more duck soup at Dien Bien is positive for influenza A/H5N1 virus. After taking a random sample from their child's case to test the test, the results showed that young cousin's death was due to influenza A/H5N1 influenza A/H1N1 infection.

Until I can specifically get a more clear translation, I do not believe the death was a combination of H5N1 and H1N1.

By Jim Wilson Veratect:

''
Reports of Co-Infection With Pandemic H1N1 And Dengue, Respiratory Syncytial (RSV), and Parainfluenza Viruses and Seasonal Influenza Strains

Since October, Veratect has received multiple reports across the world of co-infection with pH1N1 and dengue, RSV, and seasonal influenza strains in the acute clinical setting.
<o> </o>
From Octobter 27^th to Nov 4^th, Veratect reported multiple cases, pediatric and adult, of co-infections with pH1N1 and dengue in El Salvador, Barbados, and Vietnam. One fatality in El Salvador was reported with co-infection, a child. Credible laboratory evaluation was not documented in these reports, and we have not seen peer-reviewed publications on observed clinical features in these patients or other patients with documented co-infection with pH1N1 and dengue.
<o> </o>
On November 16^th and 18^th, respectively, Veratect reported single case co-infection with pH1N1 and seasonal influenza in Chelyabinskaya Oblast and Altayskiy Kray, Russia. One case was a 24-year-old pregnant woman and the other a 39-year-old woman, both deceased. Credible laboratory evaluation was not documented in these reports, and we have not seen peer-reviewed publications on observed clinical features in these patients or other patients with documented co-infection with pH1N1 and seasonal influenza.
<o> </o>
In November and in recent weeks, Veratect has reported pH1N1 co-infection with RSV in children requiring intensive care unit level intervention in the United States and Mexico. These reports were of higher credibility, as the physicians caring for these patients were interviewed directly. There was bias in reporting, as more seriously ill patients tend to be associated with more aggressive laboratory diagnostics and scrutiny. In all of the cases reported to Veratect, the clinicians expressed uncertainty as to what degree RSV versus pH1N1 contributed to the severity of illness. No fatalities were reported to Veratect to-date among those reported to be co-infected with pH1N1 and RSV. With the coming peak of RSV transmission in January and February in the US, Veratect will be vigilant for further reporting. We have not seen peer-reviewed publications on observed clinical features in these patients or other patients with documented co-infection with pH1N1 and RSV.
<o> </o>
On Dec 4^th, authorities in Mexico reported co-infections with pH1N1 and parainfluenza with no further information provided. Credible laboratory evaluation was not documented in these reports, and we have not seen peer-reviewed publications on observed clinical features in these patients or other patients with documented co-infection with pH1N1 and parainfluenza.
<o> </o>
Throughout this topical thread of reporting, we have raised some question about the term ?co-infection? being used by sources. In some instances, it appears more likely the sources are referring to co-circulation versus the dual active infection of two or more pathogens in the same patient. Especially in the case of RSV, clinical opinion is more strongly supportive of dual pH1N1-RSV infection having actually occurred in some patients resulting in a complicated clinical picture. Proper evidence-based evaluation will be required to draw firm conclusions as to the clinical significance this represents.
<o> </o>
There are several peer-reviewed studies that have documented co-infection between different seasonal type A and B influenza strains. It stands to reason pH1N1 co-infection with seasonal strains would not be unexpected. Similarly, co-infection between seasonal influenza strains and RSV has been documented in the peer-reviewed literature. It also stands to reason pH1N1 co-infection with RSV would not be unexpected. We did note publications reporting co-infection between seasonal influenza strains and parainfluenza. We did not note publications reporting co-infection between seasonal influenza strains and dengue virus.

Influenza A/H1N1 and A/H5N1 risk interact with each other

[article on the situation in Vietnam]

Updated at 17h31, on September 12, 2009
(VnMedia) - At the meeting the National Steering Committee for prevention of influenza pandemic in humans pm 9/12, Assoc. TS. Nguyen Tran Hien - Director of Institute of hygiene and epidemiology said the Central Government, translated influenza A/H1N1 still complicated development, especially with multiple risk occurring interaction between influenza A/H1N1 and influenza A/H5N1 in community.

According to survey research institute of the Central Hygiene and Epidemiology, cases of death from influenza A/H5N1 in Dien Bien past have discovered a family of patients positive for influenza A/H1N1. Meanwhile, poultry was raised in the patients were infected avian influenza H5N1.

Assoc. TS. Shows that the two types of this virus live together in one area can lead to the risk of formation of new virus strains with pathogenic stronger. Therefore, the Institute is conducting close monitoring of the outbreak evolutions in time to cope with bad situations can occur.

Re: The H5N1/H1N1 Combo mix warning thread

Brother of dying from H1N1 influenza A/H5N1 infection
Family in Dien Bien, just someone dying from influenza A/H5N1 has more people infected with influenza A/H1N1 brother.


This information was announced at the meeting the National Steering prevent pandemic influenza A/H1N1 pm 9/12.

Others, such as PV News, Vietnam has an additional male patients residing in Dien Bien death from influenza A/H5N1 and a history of eating more soup duck a week before death. Worrying is the brother of the patient is currently infected influenza A/H1N1.

At the same time, the sample of poultry in the family was positive for influenza A/H5N1. Dr. Nguyen Tran Hien - Director of Institute of hygiene and epidemiology TW concerned if the combination of two types of H1N1 virus in humans with the H5N1 virus in poultry and in humans to a new strain rate as H1N1 spreads rapidly and pathogenic H5N1 is strong as the high risk of death, many are very unpredictable.

Because mortality is too high related to influenza A/H5N1, so Central Hygiene and Epidemiology Institute and the Fund Henry Jackson Foundation (USA) have started the project "Research rates antibodies circulating H5N1 virus in humans in Hanoi, Thua Thien - Hue Tien Giang and "to make funding more than 1.6 million. The project will extend to September 2010. This is a study of influenza A/H5N1 biggest scale ever in Vietnam.:tiphat:http://www.xaluan.com/modules.php?name=News&file=article&sid=154205

Hanoi turn Wind "surveillance influenza A/H5N1
11/12/2009 08:40:50

On October 12, Ha Noi Health Department has asked the Office of Public Health Center districts, towns and coordinate with the local veterinary stations to strengthen surveillance, early detection of cases of severe pneumonia suspected by influenza A/H5N1.

Currently, experts warn: The risk of a combination of influenza virus A/H1N1 and influenza A/H5N1 virus is very close.

In particular, the epidemiological investigation of deaths due to influenza A/H5N1 by eating more of the young men next to ducks in the past, Dien Bien, Nguyen Tran Hien, Director of Institute of Hygiene and Epidemiology for Investment: After get a random sample from the cousin of young men, the results showed that people with influenza A/H1N1 positive.

Meanwhile, the poultry family of this young men positive for A/H5N1 virus.

Thus, both H1N1 and H5N1 virus exists in an environment very close and the ability to combine together, creates a new virus strain is very easy to happen.

Before this situation, the Department of Health recommends Hanoi, Hanoi is home to many household poultry, as well as crowded residential places of the country (easily contagious virus H1N1) should be able to on Left easier happen.

Thus, people absolutely not slaughter and use of poultry sickness, death must immediately notify the local authorities handled promptly; no shipping purchase poultry unknown origin, ensuring food cooked, boiled drinking; wash hands with soap before eating and after using the toilet; when symptoms of fever, cough, difficulty breathing to the right nearest medical facility for examination and treatment in time.
