Harvard University has lifted its moratorium on travel to Singapore, based on travel advice from the Centers for Disease Control (CDC), effective May 6. The University on April 30 lifted its travel moratorium for Vietnam and Toronto, Canada, based on travel advice from the World Health Organization (WHO). Harvard’s moratorium on travel to China, including Hong Kong, and Taiwan remains in effect, based on the latest information about SARS (severe acute respiratory syndrome) from the WHO and the CDC. For more information about the specifics of this moratorium, see the University’s SARS update Web page at http://www.emergency.harvard.edu/. The page is updated when new information becomes available.
