US: Outbreak of pandemic H1N1 in turkeys

The US ag authorities reported the detection of 2009 pandemic A/H1N1 influenza virus in a turkey barn with 3270 birds in Virginia.

Likely, the turkeys were recently exposed to the virus by a farm worker who had influenza-like symptoms. The farm was and remains under enhanced biosecurity.

Sequence of events:
- A significant drop in egg production was observed in one barn only (Week of November 16).

- Presumptive detection of 2009 pandemic A/H1N1 was reported to APHIS and laboratory samples were submitted to the National Veterinary Services Laboratories (November 23).
- NVSL confirmation of 2009 pandemic A/H1N1 influenza virus (November 30).

The USDA Animal Plant Health Inspection Service (APHIS) and the Virginia Department of Agriculture and Consumer Services are conducting a comprehensive epidemiological investigation of this event.
