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.

Dates of study focus:

Case farms answer questions for the time frame of 14 days prior to the onset of clinical signs or increased mortality. All questions that ask about the “reference period” refer to this time period.

Control farms answer questions for the time frame of 14 days prior to date of first detection on the matched case farm. All questions that ask about the “reference period” refer to this time period.
