China finds no human cases of bird flu in Qinghai
(Xinhua)
Updated: 2006-05-10 22:02 China has found no evidence of humans being
infected by bird flu in the remote northwestern province of Qinghai, where an
outbreak of the H5N1 strain among wild birds was reported last week, said a
Ministry of Health spokesman on Wednesday.
Experts have traveled to the infected region in Yushu County, about 800 km
from the provincial capital Xining, and medical measures have been tightened to
halt the spread of the virus, said Mao Qun'an.
However, he warned against complacency as the possibility of a large-scale
outbreak cannot be ruled out.
The Ministry of Agriculture confirmed on May 5 that wild birds found dead in
Yushu were infected with the H5N1 strain of bird flu.
The virus killed thousands of migratory waterfowls in the Qinghai Lake a year
ago and the World Health Organization (WHO) says the form of the H5N1 virus is
almost identical to the strain found in recent outbreaks in Nigeria, Iraq and
Turkey.
The Chinese Ministry of Health issued a notice last week, requiring all local
health authorities to report any human cases of unknown pneumonia and anatomize
dead bodies.
In China, 12 people are known to have died of bird flu and six have survived.
Worldwide, 115 people have died in nine countries.
The virus remains a disease in birds and is hard for humans to catch, but
health experts worry that the virus could mutate into a form that easily
transmits among humans.
