|Guangdong warns of sporadic infections of fatal bird flu, following tests on geese at market
Samples of goose meat from a Guangzhou market in have tested positive for the H7N9 avian flu virus fatal to humans.
Two goose meat samples and one sewage water sample from two poultry booths in a wet market in Zengcheng, a satellite city of Guangzhou, tested positive, Guangdong Provincial Center of Disease Control and Prevention confirmed on Sunday.
“It's serious that the water sample test is positive, because it means all the birds inside coops have the possibility of being infected with H7N9 avian influenza. The longer they stay in the coops, the risk of being infected rises,’’ said Yang Zhicong, deputy chief of the Guangzhou municipal CDCP. The city government of Guangzhou, the provincial capital, is tracking the poultry source. The market was shut down on Saturday for three days, Xinhua reports.
Meanwhile, 17 sales people working in nine poultry booths in the market are undergoing a week-long medical observation. So far, they have shown no signs of being infected with the bird flu, said Yang.
Bird flu, or avian influenza, is a contagious disease of animal origin caused by viruses that normally only infect birds and, less commonly, pigs. It can be fatal to humans.
Six human cases of H7N9 bird flu have been confirmed in Guangdong Province since August. None is from Guangzhou.
“According to expert assessments, Guangdong faces an extremely high risk of sporadic human H7N9 infections in winter and next spring," said Zhang Yonghui, head of the provincial CDCP.
“The cases may occur at any time across the province and the Pearl River Delta region requires special attention," Zhang said.
The Chinese mainland has reported more than 140 human cases of the deadly virus since it emerged in March, including 45 fatalities.
