SARS outbreak contained worldwide: threat remains and more research needed

摘要

The World Health Organization (WHO) is removing Taiwan, China, from the list of areas with recent local transmission of severe acute respiratory syndrome (SARS). Taiwan is the last area to be removed from the list. It has been 20 days, or two consecutive 10-day incubation periods, since the last case on June 15. Based on country surveillance reports, the human chains of SARS virus transmission appear to have been broken everywhere in the world. However, due to the many questions remaining about SARSand the possibility that cases may have slipped through the surveillance net, WHO warns that continued global vigilance for SARS is crucial for the foreseeable future. The world is not yet SARS-free.
