"The World Health Organization (WHO) today began recommending that persons travelling to Hong Kong Special Administrative Region of China and Guangdong Province, China consider postponing all but essential travel. This updated travel advice comes as a result of new developments in the multi-country outbreak of severe acute respiratory syndrome (SARS)."
The new travel advice is intended to limit further international spread of SARS by restricting travel to areas where the transmission patterns of SARS are not fully understood. The SARS situation, which is rapidly evolving, is under constant assessment by WHO in collaboration with three global networks of experts. The new advice is issued as part of a series of measures that will change as more information about SARS becomes available.
