Chinese girl sick with H9N2 infection
A 4-year-old girl in China's Guangdong province is sick with an H9N2 avian influenza infection, according to a translated report posted Jun 18 by FluTrackers, an infectious disease message board.
The provincial Health and Family Planning Commission said the child, who lives in the city of Meizhou, is hospitalized in serious condition, according to FluTrackers. Guangdong health officials warned the public to avoid live-bird markets and not to buy poultry products of unknown origin.
H9N2 viruses are found in poultry in parts of Asia, Africa, and the Middle East, and human cases occur sporadically. The illness is usually mild. The World Health Organization said in May that the global count of confirmed human H9N2 cases was 28, with no deaths and no cases of person-to-person transmission.

Avian flu viruses hit poultry and wild birds in China, Taiwan, and Russia
Avian flu of the H5N6 subtype recently struck a farm in south-central China, while Taiwan has detected three more H5N2 outbreaks in poultry, according to official reports today. In addition, a surveillance program in Russia has detected H5 viruses in wild birds near the Mongolian border.
In China, the H5N6 outbreak began Jun 7, sickening 605 birds and killing 293 on a farm in Hunan province, according to a report that Chinese officials filed with the World Organization for Animal Health (OIE) today. It said 29,625 birds were destroyed to prevent further spread of the virus. The source of the virus was unknown.
China has submitted 15 reports on H5N6 outbreaks in poultry since the virus emerged in August 2014. In addition, at least 15 human infections with the virus have been reported since April 2014, including one reported in Hunan province in late May of this year.

In Taiwan, highly pathogenic H5N2 avian flu was found on a farm and in two slaughterhouses on the western side of the island, officials told the OIE in another report submitted today.
At the farm, located in Yunlin County, 3,224 of 13,580 chickens died in an outbreak that began May 30, and the rest were destroyed to prevent further spread.
Suspicious signs in chicken carcasses led to testing and detection of the virus in the two slaughterhouses, in Taichung City. Nineteen carcasses were destroyed at one of the facilities, and in the other, 68 chickens died of the infection, prompting destruction of 427 additional birds as a precaution. Samples from the farms of origin are being tested by the national laboratory.
Jun 20 OIE report from Taiwan
In still another report to the OIE, Russian officials on Jun 17 said 17 wild birds that were shot for surveillance reasons near the Ubsu-Nur Lake along the Mongolian border were found to carry H5 avian flu viruses. The species included grey herons, great crested grebes, black-headed gulls, common terns, great cormorants, and a duck of unspecified type.
Genetic sequence analysis showed that the isolates belong to the highly pathogenic H5 lineage that was first detected in Guangdong, China, in 1996, the report said.
