EPIDEMIOLOGICAL COMMENTS
An intensive surveillance system is in place for avian influenza virus including screening at Mai Po Nature Reserve (Reserve) in Hong Kong. Among the environmental samples collected by the University of Hong Kong on 6 December 2023, a sample of wild bird fecal dropping has been confirmed to be positive for H5N1. Another sample of wild bird fecal dropping collected on 6 December 2023 was also confirmed to be positive for H5N1. A dead Eurasian Teal collected at the Reserve on 8 December 2023 was tested positive for H5N1. A dead Pin-tailed snipe and a dead Eurasian Teal collected at the Hong Kong Wetland Park (Wetland Park) on 19 December 2023 were tested positive for H5N1. A dead Eurasian wigeon collected on 21 December 2023 at the Wetland Park was tested positive for H5N1. A Eurasian wigeon which received treatment at the Kadoorie Farm and Botanic Garden (KFBG) was collected earlier from the Wetland Park and humanely dispatched later and tested positive for H5N1. The organisations managing the reserve, KFBG and the Wetland Park have stepped up cleaning and disinfection of visitor facilities. The government is closely monitoring the situation of the birds in the reserve, KFBG and the Wetland Park. The government has closely monitored the situation of the local poultry farms and wholesale market. Poultry farmers, pet bird shop owners and licensed holders of pet poultry and racing pigeons are reminded from time to time to ensure that proper precaution against avian influenza have been implemented.
