GUANGZHOU, Aug. 9 (Xinhua) -- A new suspected case of human infection with the H7N9 strain of avian influenza was reported on Friday in south China's Guangdong Province.
The Guangdong Provincial Department of Heath announced that the sample from a female patient in Huizhou City had tested positive for the virus in initial tests on Tuesday.
The 51-year-old woman, surnamed Chen, is in critical condition, the department said. She is now being treated in Huizhou City Central People's Hospital.
Chen had been a poultry slaughtering worker in a local market for many years, the department added.
Thirty-six people who had close contact with her have been put under medical observation. They have shown no abnormal symptoms so far.
A native of Boluo County, Huizhou, Chen tested positive for H7N9 in the Huizhou City Center for Disease Control and Prevention on Tuesday.
The result was later confirmed when it was checked by the Guangdong Provincial Center for Disease Control and Prevention.
The provincial department has dispatched a team of five medical experts to the hospital to help with Chen's treatment.
The Guangdong Provincial Agricultural Department has allocated five tonnes of disinfectant for prevention of further spreading of the virus.
Chen's sample has also been submitted to the Chinese Center for Disease Control and Prevention for confirmation.
The Chinese mainland has reported over 130 human infections with H7N9 including 43 that ended in death, mostly in spring, since the virus emerged in February.
