  • Taiwan - 2 workers being monitored after exposure to H5N6 positive wild bird in park - December 5, 2017

    Press release

    In the domestic season of bird flu epidemic, migratory birds have been detected H5N6 virus, please follow the "5 to 6 not" principle


    Yesterday, the Agriculture Commission of the Executive Yuan confirmed the body of a black-faced Spoonbill who had been picked up by the National Taiwan Strait Park and detected a H5N6 subtype of highly pathogenic avian influenza. The Census and Statistics Department said that a total of 2 contact persons were staff members. N95 facemasks and gloves were worn during pick-up. No flu-like symptoms are presently available. The health units will conduct health monitoring for 10 days and assist them in seeking medical treatment if flu-like symptoms occur.
    According to COC data, the H5N6 strain detected this time is different from the H5N6 strain previously reported in the country, but close to the virus isolates from the wild birds in Shimane Prefecture, Japan in November this year. Japan Tottori University released genetic analysis showed that the "island-type" H5N6 strain was recombined by the HxN6 transmitted in the last quarter of the highly pathogenic H5N8 epidemic in Europe and wild European and European waterfowl, although highly poultry birds However, there is no evidence that the virus can be transmitted from bird to bird, the human health threat is low and no human infection occurs. Please do not panic.
    In addition, the Health and Family Planning Commission of Yunnan Province of China released the first case of H7N9 influenza in the current epidemic on December 2, which is a 64-year-old man in Xundian County, Kunming. Based on the potential risk of environmental exposure in the Mainland, the Disease Control Department (DH) will promptly upgrade the provincial tourism outbreak recommendation to the second-level alert (Alert) and inform the MAC. A total of 1 case of H7N9 influenza has been reported in the Chinese mainland so far this year. A total of 5 cases have been reported in the world since 2013, with a cumulative total of 1,565 cases. The World Health Organization (WHO) recorded 612 deaths by September 27 this year with a mortality rate of nearly four to make.
    In response to the recommendations of the new type A influenza epidemic in mainland China, Jiangsu Province, Guangdong Province, Anhui Province, Hunan Province, Fujian Province, Guangxi Zhuang Autonomous Region, Guizhou Province, Liaoning Province, Hebei Province, Shaanxi Province, Xinjiang Uygur Autonomous Region, Inner Mongolia Autonomous Region and Yunnan travel outbreak recommendations as the second level: Alert (Alert), other provinces (excluding Hong Kong and Macao) and Indonesia as the first level: Watch (Watch).
    To prevent the new type A influenza, follow the "5 to 6 No" principle. "5 to": Poultry and eggs should be cooked thoroughly. Use soap to wash your hands thoroughly. Symptoms may occur. Wear a mask and seek medical attention. Long-term contacts of birds should be vaccinated against influenza to balance their diet and proper exercise. "6 No": No raw eggs or products, no smuggling or purchase of poultry or meat products, and no contact with or feeding on migratory birds and poultry Birds, non-wild animals and birds that are discarded at will are not to be mixed with other livestock and poultry and do not go to places where the air is not circulated or crowded. People found dead dead birds, do not pick up the handling, please call the Commission for Disease Control and Quarantine of Animal Husbandry and Quarantine Free Immunity Advisory Line 0800-761-590. Information on bird flu and new influenza A may be obtained from the UNDC Global Information Network ( http://www.cdc.gov.tw ) or by calling the toll free number 1922 (or 0800-001922).

    Epidemiological comments On 1 December 2017, one dead black-faced spoonbill was found in Taijiang National Park (Republic of China) by the staff of the National Park and was sent to the National Laboratory (Animal Health Research Institute, AHRI) by the local Livestock Disease Control Center (LDCC). H5N6 subtype of highly pathogenic avian influenza was detected and confirmed by the AHRI in the evening of 4 December 2017. The LDCC disinfected the neighboring areas of the spot where the dead black-faced spoonbill was found and has completed clinical examination and sampling of all poultry farms (four chicken farms) within 5 km radius of the spot. All chicken in the four farms are clinically healthy. They are under intensified surveillance for three months to detect, if any, spreading of the virus. In addition, to be further well-prepared for the increased risk of HPAI epidemics, the government have launched active surveillance over three categories of higher risk poultry farms: (1) poultry farms located within 3 km radius around wetlands nationwide; (2) outdoor feeding duck farms; and (3) native chicken farms. According to preliminary analysis by the AHRI, the current H5N6 virus is different (identity 92.4%) from the H5N6 virus that was detected in February 2017, but is closely related to the one found in wild birds in Japan last November. The HA genomic sequences share about 99% identity with the H5N8 virus which has caused major outbreaks in Europe from late 2016 to early 2017. The NA genome is similar to the HxN6 which is widespread in wild birds in Eurasia.
