Avian flu hits poultry in Vietnam, Nepal
Avian flu has been confirmed in flocks of ducks and chickens in Vietnam and Nepal. Local officials in Dak Lak province in Vietnam's central highlands destroyed a flock of more than 1,300 domestic ducks and 9,800 duck eggs after H5N1 affected an unspecified number of the birds, according to a story today from Bernama, Malaysia's national news agency. Local agriculture authorities also sanitized the farm and surrounding areas. The outbreak began after the farmer bought ducks from another farm in the province that had an unreported H5N1 outbreak earlier this month, according to the story. The earlier outbreak resulted in the death of more than 5,000 ducks.
In Nepal, more than 500 ducks and chickens were culled after an avian flu outbreak on a farm in Bhaktapur district, Nepal News reported today. Lab results on samples tested in the United Kingdom confirmed avian flu after preliminary tests in Nepal. The story did not specify the number of poultry affected, but the Nepal-based Daily Kantipur reported today that 35 chickens died on the farm earlier this month. In July the country had been declared free of avian flu, according to the Nepal News story.

US sees little flu activity
Flu activity in the United States still remains at low levels, with most indicators below their baselines, the US Centers for Disease Control and Prevention (CDC) said yesterday in its surveillance report for the week ending Nov 19. The percentage of respiratory specimens that tested positive for flu was 1.0%, a slight decrease from the 1.2% reported the previous week. The percentage of doctor's visits for flulike illness, at 1.3%, stayed below the national baseline of 2.4%. Deaths from pneumonia and flu dipped slightly and were at a level expected for this time of year, the CDC said. Two pediatric flu deaths were reported, but they occurred during the 2010-11 season, raising that total to 118. So far the CDC has received no reports of pediatric flu deaths for the new flu season. Sporadic flu activity was reported by the District of Columbia, Guam, Puerto Rico, and 26 states, an increase of three from the previous week.
