Avian influenza H7N3 strain makes appearance in Vietnam

24/12/2007

VietNamNet Bridge - The dangerous, human-transmissible avian influenza A (H7N3) strain, previously recorded in Korea, Canada and Holland, has reemerged in several Asian countries including Vietnam, according to the National Steering Committee for Avian Influenza Prevention and Control.

The committee held a conference on Tuesday in Ha Noi to discuss the country?s response to the recent reoccurrence of the deadly bird flu.

The H7N3 virus found in Vietnam, however, is classified as low-pathogenic, not readily transmitted to humans.

The committee has made plans already to import more H7N3 avian influenza vaccines to prevent possible outbreaks.

According to the Ministry of Agriculture and Rural Development, the H5N1 strain reappeared in the northern Cao Bang province?s Bao Lam District. Lower temperatures and poultry smuggling from China in the northern provinces have also increased the risk of another outbreak of bird flu in several provinces there.

The committee is directing local officials to improve environmental sanitation in high-risk areas and tighten their control over the transportation of poultry through borders.

No report of any case of H7N3 being transmitted to a human being has been received by the Ministry of Health from the World Health Organization (WHO), he added.

Nga added that, over the last four months, no new case of H5N1 in humans has been reported, but the dangerous virus still exists in poultry in some areas.

Nga said it is still possible the country may experience a reoccurrence of widespread bird flu or H5N1 human infections as lower temperatures in the winter-spring period aid the mutation of the virus.

The Health Ministry has tightened control over environmental sanitation in areas previously hit by bird-flu epidemics and it is to conduct a bird flu drill besides carrying out measures at entry points to prevent suspected poultries from entering the nation in January 2008.

Re: H7N3 in Vietnam

Co-circulation of A/H5N2 and A/H7N3 (LPAI) has been detected in Italy since June 2007. Although the media coverage was null, there were at least twenty epizootics both in backyard poultry and large broilers / incubators farms. Since end of november a vaccination campaign is undergoing.
According the IZSVE (OIE Reference Laboratory in Padua for AI), the strains involved belong to ''Euro Asian'' lineages. For more info, see ''EUROPEAN SURVEILLANCE FOR BF'' thread.

Re: H7N3 in Vietnam

Outbreak in the Netherlands in 2003 was H7N7.

Outbreak in South Korea was H7N8. North Korea was H7 (N not dislcosed). The most recent outbreak in Engalnd was H7N2. I think the quote was citing H7 outbreaks, which are all readily transmitted to humans.

Child dies, bird flu suspected

26/12/2007

VietNamNet Bridge ? A four-year-old child from Moc Chau District in the northern mountainous province of Son La died several days ago at the Hanoi-based Central Pediatrics Hospital from bird flu-like symptoms, reported the Ministry of Health.

The child was hospitalized with a seriously high temperature and pneumonia.

Before becoming ill, the child ate chicken. Doctors suspect the child died of bird flu. They are conducting tests to determine the precise cause of death.

Vietnam has not had any reports of bird flu in humans in recent months; but in early December 2007 the Veterinary Agency under the Ministry of Health warned of the appearance of the highly toxic H7N3 virus in other Asian countries and cautioned it could appear in Vietnam.
