    Notes:

    Waiting for details on these: "Among the 4 confirmed cases of human infection with H9N2 avian influenza, 1 male and 3 females, aged from 3 to 14 years old, were 2 from Huanggang City, Hubei Province, 1 from Nanning City, Guangxi Zhuang Autonomous Region, and 1 from Zhenjiang City, Jiangsu Province. 4 were mildly ill; all had contact with poultry or visited live poultry markets before the onset of symptoms." link

    "A total of 28 laboratory-confirmed cases of human infection with avian influenza A(H9N2) viruses, none fatal, have been detected globally. In most human cases, the associated disease symptoms have been mild and there has been no evidence of human-to-human transmission. Influenza A(H9N2) viruses are enzootic in poultry populations in parts of Africa, Asia and the Middle East. The majority of viruses that have been sequenced belong to the A/quail/Hong Kong/G1/97 (G1), A/chicken/Beijing/1/94 (Y280/G9), or Eurasian clades." WHO report dated February 25, 2016 link


    "..there were five H9N2 cases found in mainland China in 1998 and 1999, respectively, and three human H9N2 AI cases reported in Hong Kong in 1999 and 2003 respectively." WHO link
