Interim Travel Advisory: Mainland China
(Updated May 8, 2003, 12:30 PM ET; Released March 13, 2003)

The Centers for Disease Control and Prevention (CDC) has been working closely with the World Health Organization (WHO) to investigate cases of Severe Acute Respiratory Syndrome (SARS). The number of cases of SARS is subject to change as surveillance increases and cases are identified and confirmed. The current case count for the United States can be found at this web site. The case count for cases outside the USA can be found at this site. Cases in travelers have been epidemiologically linked to travel to mainland China.

CDC issues two types of notices to travelers: alerts and advisories. CDC has issued a travel advisory for mainland China advising people planning elective or nonessential travel to China may wish to postpone their trips until further notice.

The SARS outbreaks appear to primarily involve health-care workers and close family contacts of suspect cases. Health authorities are on the alert for people who have specific symptoms of respiratory illness. The case definition for suspected SARS is subject to change, particularly with regard to travel history, as illness is reported in other geographic areas. The most current U.S. definition can be accessed at the Severe Acute Respiratory Syndrome (SARS) case definition web page.

CDC is distributing health alert notices about SARS to people traveling to the United States from Hong Kong. Travelers to Hong Kong should monitor their health while there and for at least 10 days after departure from Hong Kong. If fever or respiratory symptoms (for example, cough or shortness of breath) develop, a visit to a health-care provider is strongly recommended. The provider should be informed about the symptoms in advance so arrangements can be made, if necessary, to prevent transmission to others in the health-care setting (see Updated Interim Domestic Guidelines for Triage and Disposition of Patients Who May Have SARS)

• Notify at the earliest possible time the nearest U.S. Public Health Service Quarantine Station.
• Alert the destination port of any passengers meeting the above criteria.
• Refer all arriving passengers who are symptomatic to health authorities for assessment and care.
• Inform passengers and crew that there is/was a suspect case of SARS on board.
• The passengers and crew should provide all their contact information for the subsequent 14 days to the port health authorities.

The U.S. Department of State (DOS) has authorized the departure, on a voluntary basis, of non-emergency employees and all family members at the U.S. Embassy and selected consulates in China. The Department of State warns U.S. citizens to defer nonemergency travel to mainland China at this time. The full text of this announcement is available on the State Department website.

Because of limitations in medical evacuation services for SARS patients, travelers and resident expatriates should continue to monitor the U.S. Department of State website for updates on availability of medical services and medical evacuations in China. See this website for more information.
