The World Health Organization has added Beijing and China’s Shanxi province to a list of places travelers should avoid, as well as Toronto, Canada. Canadian health officials and Toronto’s mayor lashed out against the warning. But the World Health Organization noted people now suffering from SARS in other countries appear to have caught the virus in Toronto, the only city outside Asia to have had deaths associated with the syndrome. Beijing announced four more deaths from the SARS virus and sealed off a major hospital to avoid spread of the disease. A BBC correspondent says there’s a sense of spreading alarm in the Chinese capital with panic buying of rice and salt. In Shanghai, a visiting expert from the World Health Organization, Dr. Wolfgang Peiser, has said he believed there were tens of SARS cases in the city rather than the two confirmed cases being officially reported. Chinese authorities closed Beijing’s schools for two weeks yesterday, a move that will affect up to 1.7 million children.
