2020年3月19日
由于COVID-19在全球带来的影响，美国国务院建议美国公民避免所有国际旅行。在民航出境班机仍在运作的国家，住在美国的美国公民应安排立即返美，除非他们已做好在国外无限期滞留的准备。住在国外的美国公民应避免所有国际旅行。许多国家正在经历COVID-19疫情大爆发，正在实施旅行限制和强制隔离，关闭边境，突然告知情况下限制非本国公民入境。航空公司取消了许多国际航班，一些邮轮公司也暂停运营或取消了行程。如果你选择出国旅行，你的旅行计划可能会被严重打乱，你可能会被迫无限期地滞留在美国境外。
位于世界各地的美国外交或领事人员与其家属，若判定他们如曝露于COVID-19会有更严重后果的较高风险，或是基于同等理由提出撤离要求的，美国国务院于3月14日授权其撤离。这些人员的撤离可能限制美国使领馆为美国公民提供服务的能力。

Global Level 4 Health Advisory – Do Not Travel
U.S. DEPARTMENT OF STATE Office of the Spokesperson For Immediate Release MEDIA NOTE
March 19, 2020
The Department of State advises U.S. citizens to avoid all international travel due to the global impact of COVID-19.  In countries where commercial departure options remain available, U.S. citizens who live in the United States should arrange for immediate return to the United States, unless they are prepared to remain abroad for an indefinite period.  U.S. citizens who live abroad should avoid all international travel. Many countries are experiencing COVID-19 outbreaks and implementing travel restrictions and mandatory quarantines, closing borders, and prohibiting non-citizens from entry with little advance notice.  Airlines have cancelled many international flights and several cruise operators have suspended operations or cancelled trips. If you choose to travel internationally, your travel plans may be severely disrupted, and you may be forced to remain outside of the United States for an indefinite timeframe.
On March 14, the Department of State authorized the departure of U.S. personnel and family members from any diplomatic or consular post in the world who have determined they are at higher risk of a poor outcome if exposed to COVID-19 or who have requested departure based on a commensurate justification.  These departures may limit the ability of U.S. Embassies and consulates to provide services to U.S. citizens.
For the latest information regarding COVID-19, please visit the Centers for Disease Control and Prevention’s (CDC) website.
You are encouraged to visit travel.state.gov to view individual Travel Advisories for the most urgent threats to safety and security. Please also visit the website of the relevant U.S. embassy or consulate to see information on entry restrictions, foreign quarantine policies, and urgent health information provided by local governments.
Travelers are urged to enroll in the Smart Traveler Enrollment Program (STEP) to receive Alerts and make it easier to locate you in an emergency. The Department uses these Alerts to convey information about terrorist threats, security incidents, planned demonstrations, natural disasters, etc. In an emergency, please contact the nearest U.S. Embassy or Consulate or call the following numbers: 1(888) 407-4747 (toll-free in the United States and Canada) or 1 (202) 501-4444 from other countries or jurisdictions.
