      On December 11, the Ministry of Agriculture and Rural Affairs received a report from the China Center for Animal Disease Control and Prevention, confirmed by the National Avian Influenza Reference Laboratory, that a wild bird H5N1 subtype of highly pathogenic avian influenza occurred in the wild tidal flats of Tantou Town, Changle District, Fuzhou, Fujian Province. During the epidemic, 7 wild red-necked ducks and other wild birds died.
      After the outbreak of the epidemic, the local government immediately carried out standardized treatment in accordance with the requirements of relevant emergency plans, and carried out monitoring and inspection of surrounding poultry. No abnormalities in poultry were found.
      This is the third officially announced bird flu epidemic in China this year and the first this winter:
      1. An epidemic of highly pathogenic avian influenza H5N1 subtype occurred in wild birds in Qinghai Province
      On July 22, the Ministry of Agriculture and Rural Affairs received a report from the China Center for Animal Disease Control and Prevention. Confirmed by the National Avian Influenza Reference Laboratory, an H5N1 subtype highly pathogenic avian influenza epidemic occurred in Gangcha County and Gonghe County, Qinghai Province, resulting in death. 273 wild birds.
      2. An avian influenza epidemic occurred in Xinjiang, and 5,182 wild birds were culled.
      On July 28, the Ministry of Agriculture and Rural Affairs received a report from the China Animal Disease Prevention and Control Center that a wild bird H5N1 subtype highly pathogenic avian influenza epidemic occurred in Nagqu City, Tibet Autonomous Region. 5,182 wild brown-headed gulls and other wild birds died. The epidemic point was 3 There are no poultry farmers within kilometers.
      Currently, avian influenza is still spreading in Europe, America, and Asia, such as the United Kingdom, France, Germany, Poland, the United States, Canada, South Korea, and Brazil. In addition, there are two special circumstances in this bird flu epidemic. For example, bird flu also occurred in waterfowl in the United States, and more than 900 seals and sea lions in Brazil died of bird flu.
      About 30,000 ducks culled due to bird flu outbreak in U.S. waterfowl
      The first commercial case of highly pathogenic avian influenza occurred in Georgia, the largest poultry-producing state in the United States, and approximately 30,000 ducks were culled.
      The infection was reported by both the Georgia Department of Agriculture (GDA) and the United States Department of Agriculture (USDA) Animal and Plant Health Inspection Service (APHIS). APHIS refers to this flock type as a commercially raised waterfowl flock for release, and the GDA further identifies the affected birds as ducks. The affected flock is located in Sumter County and involves approximately 30,000 chickens, according to APHIS.
      More than 900 seals and sea lions die from bird flu in Brazil
      Relevant authorities in Brazil said on the 10th that 942 seals and sea lions had been confirmed to have died due to infection with the highly pathogenic avian influenza virus in the southern state of Rio Grande do Sul, an unprecedented number.
      Silvina Botha, an oceanographer at the Federal University of Rio Grande do Sul, recommends burying or burning the carcasses as soon as possible to reduce the risk of infection to humans or other animals.

        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.
