The Health and Family Planning Commission of Henan Province reported an additional human case of avian influenza A(H7N9) in a 38-year-old man from Kaifeng who is in critical condition.
Hong Kong health officials who are closely monitoring the situation said, “Since late 2016, the number of human H7N9 cases reported in the Mainland hugely increased from six in November 2016 to 106 in December 2016 and 183 last month as of January 29, 2017. The number of cases in this wave so far has been much higher than that in the same period last winter. Cases imported from Guangdong have also been reported in Hong Kong, Macau and Taiwan.
“According to the Chinese Center for Disease Control and Prevention, about 90 per cent of the patients reported exposure to live poultry, mostly with exposure to live poultry markets (LPMs). There was also an increase in environmental contamination with H7N9 virus as reflected by the positive rate of environmental samples collected from LPMs or other live poultry-related environments in affected provinces.”
Since the first human cases were reported in 2013, there has been 1107 cases as of Feb. 6.
