Ultraviolet radiation and heat can kill the SARS coronavirus
effectively, a Chinese scientist said here Tuesday at the ASEAN
(Association of Southeast Asian Nations), China, Japan and the
Republic of Korea High-level Symposium on SARS.
Dong Xiaoping, vice director of the Institute of Virology at
China's Center for Disease Control and Prevention, said that the
lifespan of the coronavirus, the cause of SARS (severe acute
respiratory syndrome), reduced as the temperature rose.
The research group, led by Dong, revealed that the coronavirus is
sensitive to high temperatures, surviving five days at 24 degrees
Celsius, just 90 minutes at 56 degrees Celsius and 30 minutes at 75
degrees Celsius.
According to Dong, the ultraviolet rays emitted at 10 a.m. on a
sunny May day in Beijing can kill the virus in three hours.
The two-day meeting, kicked off by Chinese Executive Vice Minister
of Health Gao Qiang Tuesday morning, will discuss the important
issues of SARS prevention and control.
