a The viruses (n = 132) were grouped according to the frequency of isolations (cases) on each farm and to the source species (duck and/or chicken). Two types of visit were conducted on the study farms; bi-monthly longitudinal survey (LS) and investigations of disease outbreaks (DI). An event is the sampling date in which virus isolations were made.
