Detecting the disease agent
Surveillance
The term surveillance describes an active process in which disease occurrence data is collected, analysed, evaluated, and reported to animal health agencies tasked with disease control. The term monitoring is usually used for a more passive process although in common usage both terms are often used interchangeably. Because of the substantial cost involved, programs often encompass several diseases at the one time.
