| Epidemiological comments |
One dead Grey heron (Ardea cinerea) was found in Guandu Park in Taipei City by the staff of Taipei City Animal Protection Office (APO) and was sent to the National Laboratory (Animal Health Research Institute, AHRI) on 20 March 2019. H5N2 subtype HPAI was detected and confirmed by the AHRI in the evening of 22 March 2019. The APO disinfected the neighboring areas of the spot where the Grey heron was found and has completed clinical examination and sampling of all poultry farms (7 chicken farms) within 3 km radius of the spot. All chicken in the 7 farms are clinically healthy. They are under intensified surveillance for 3 months. If any positive farms are detected from the intensified surveillance, they will be included into the HPAI reports for poultry. | |
