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 9 November 2022, a sample of wild bird faecal droppings has been confirmed to be positive for H5N1. The organisation managing the Reserve has stepped up cleansing and disinfection of visitor facilities. The Government is closely monitoring the situation of the birds in the Reserve. There are no poultry farms within three kilometres of the Reserve. The Government has recently strengthened AI surveillance and closely monitored the situation of the local poultry farms and wholesale market. Poultry farmers, pet bird shop owners and licence holders of pet poultry and racing pigeons are reminded from time to time to ensure that proper precautions against avian influenza have been implemented.
