The World Health Organization lifted its advisory against travel to Toronto because there have been no new SARS cases in the community at large for 20 days, but Toronto remains an affected area. If new SARS cases appear here, the travel advice will be reevaluated. WHO also reported that the outbreak appears to have peaked in Hong Kong and Singapore but is still on the increase in China. Advisories against nonessential travel to Beijing, Hong Kong, and Guangdong and Shanxi provinces remain in effect. Vietnam has been removed from the list of affected countries because it has brought the disease under control.
