The Institute of Virology under the Chinese Center for Disease
Prevention and Control has been isolated and all staff in contact
with the affected areas have been quarantined.
The information was released by Liang Wannian, deputy director
of the Beijing municipal health bureau on Monday.
The quarantined staff will be discharged from medical
observation if they show no SARS symptoms within the coming 14
days, Liang said.
Since April 22, China has reported two diagnosed and six
suspected SARS cases in Beijing and east China's Anhui
province.
Since the Anhui diagnosed SARS patient and one Beijing suspected
SARS patient used to work at the same laboratory in the Institute
of Virology, experts held that the epidemic might have been caused
by laboratory infection.
