Should I cancel my international trip?
CDC recommends that travelers avoid all nonessential international travel because of the COVID-19 pandemic. Some health care systems are overwhelmed and there may be limited access to adequate medical care in affected areas. Many countries are 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 in-country travel may be unpredictable. If you choose to travel internationally, your travel plans may be disrupted, and you may have to remain outside the United States for an indefinite length of time.
CDC also recommends all travelers defer all cruise ship travel worldwide.
