(CNN) — For much of 2021, US passport holders have seen an ever-changing list of international travel options as the world adapted first to vaccines and then to the Delta variant of the coronavirus.

Total US cases are around the 42.3 million mark since the pandemic started. Some nations are overwhelmed by Covid cases as well as some US states.

In the end, it’s up to you to decide whether travel to international destinations is a good idea. The health risks are obvious if you’re not fully vaccinated. Nations might change their rules at any time. You may have to adhere to strict curfews and mask mandates. Violations could involve big fines and even jail time.

If you want expert input into your decision, the US State Department and the Centers for Disease Control and Prevention provide Covid-19 risk assessments by country. Both agencies rate many of the countries open to US travelers at Level 4, the highest risk for Covid-19. Also, remember that all air passengers 2 and older must show proof of a negative Covid-19 test that’s no more than three days old to enter the United States.

List of nations

What follows is a curated, alphabetical list of countries and territories where it’s still possible for US passport holders to go for a vacation. Click the links at the end of each destination for important information on:

— Presenting negative results from Covid-19 tests to enter (including time limits to take the test, types of tests allowed and additional tests upon arrival).
— Quarantines (if any) and health screenings.
— Possible exemptions from the rules for the fully vaccinated, people recovered from a recent case of Covid-19 or children.
— Health insurance requirements, curfews and lockdowns.
— Different rules if you’re arriving from a third country vs. the United States.

These are all things you need to research before you book your trip. People testing positive for Covid-19 upon arrival or while visiting can expect to go into quarantine. Rules for land entry may be different.
