(CNN) — Once one of the world's most powerful travel documents, the might of the US passport has been diminished during the pandemic. With US Covid-19 cases now beyond the 25 million mark, some nations continue to view American vacationers warily. In the end, it's up to you to decide whether travel to international destinations is a good idea. There are obvious health risks. Nations might change rules at any time. You may have to follow stricter curfews and mask mandates than Americans are used to. Violations could involve hefty fines and even jail time. The US Centers for Disease Control and Prevention and the US State Department provide Covid-19 risk assessments by country. Also keep this important change in mind: Starting January 26, all air passengers aged two and older must show proof of a negative Covid-19 test that's no more than 72 hours old to enter the United States. That includes US citizens returning from trips to other countries. Be sure to get information on testing sites in your destination for your return trip before you go. US embassies report some places are having trouble returning test results within the 72-hour window.
"Seriously reconsider going overseas right now," acting Assistant Secretary of State for Consular Affairs Ian Brownlee told reporters on a call Tuesday. "US citizens who choose to go abroad, whether it's for a holiday or a genuine emergency, everyone needs to be prepared to be potentially seriously disrupted in their trips."
"If you cannot easily access a Covid-19 test, or if you test positive, you will end up overseas for much longer than you planned," Brownlee added. "If that happens, you will be responsible for covering your own lodging and medical costs during that time."
What follows is a list of countries, in alphabetical order, where it's still possible for US passport holders to go for a vacation if they're willing to take the risks:
Set on the Adriatic Sea, Albania remains open. The US Embassy website states that while there's no Covid-19 test requirements or quarantine to enter, you can expect a health screening. Mask requirements and new curfews are in place.
