Taiwan has declared to the World Organisation for Animal Health that its H7N3 low pathogenic notifiable avian influenza outbreaks have been resolved and that it has regained free status.

The country discovered sub-clinical H7N3 LPAI on a duck breeder farm in late March. The outbreak was detected as part of intensified surveillance in the three-kilometer radius around an H5N2 outbreak indentified earlier in the month. A second outbreak was then recorded within this surveillance area.

Control measures included quarantine, movement control within the country, screening, zoning and disinfection of infected premises. Intensified and active surveillance performed on surrounding farms within the radius of both index farms — a total of 169 farms, including 37 farms overlapping with surrounding farms of the H5N2 outbreak farm — and in the whole territory has shown no outbreaks of notifiable avian influenza.
