Instructions

The U.S. Department of Agriculture (USDA) Animal and Plant Health Inspection Service (APHIS) and state and industry partners are conducting a case-control study as part of the highly pathogenic avian influenza (HPAI) investigation efforts to identify factors that may contribute to the transmission of H5N1 influenza virus to poultry.


We are asking you to fill out this survey to provide information on daily farm activities, facility and premises condition, deliveries to the farm, and ill birds. This survey covers a 2-week (14-day) period on the farm starting on a specific date that we will provide. We recommend using a pocket calendar or other agenda manager and any feed and other delivery records that might be available to assist in recalling the requested information.


Term

Case definition

Control definition

Premises

Farm location with flocks confirmed to be HPAI H5N1 infected by NVSL, including all barns and buildings, even if not all barns and buildings contain infected birds.

Farm location with no HPAI H5N1 infected birds in any barn or building, in same state as case farm.

House/barn

Barn or building that houses HPAI H5N1-infected birds.

On control premises, a barn or building that does not house any HPAI H5N1 infected birds.
