The United States has had one of the worst coronavirus outbreaks in the world, with more than 36.6 million cases and 621,253 deaths as of Aug.15, 2021, according to Johns Hopkins University . Despite a new surge in cases from the delta variant, travelers are again exploring the world.

Indeed, the welcome mat that had been rolled up for Americans for much of 2020 is now back in place, and more than 110 countries and territories have reopened to U.S. tourists, including Iceland, which began allowing in vaccinated U.S. travelers as of April 6, 2021, and Greece, which did the same as of April 19, 2021. France opened to fully vaccinated tourists as of June 9, 2021, Spain began welcoming fully vaccinated Americans on June 7, 2021 and Denmark reopened to fully vaccinated U.S. citizens on June 5, 2021 .

Unfortunately, many South American countries are currently COVID-19 hot spots, as are India and several other nations in Asia. Most of Oceania remains off limits (but French Polynesia has reopened to Americans ). Europe has also now mostly reopened to Americans. Even England is now open to Americans.

There are no testing requirements for visitors, but a health screening at the airport is mandatory.

COVID-19 test required: Yes

• Three to five days (72 to 120 hours) before departure, again upon arrival and a third time on day 7 or 14 (if not vaccinated) • PCR test required (including infants and toddlers)

Other restrictions: Travel Authorization is required for short-stay tourists and anyone seeking to work from Anguilla. Each individual traveler (including children) needs an authorization, and travelers entering/transferring via Dutch St. Maarten also must complete St. Maarten's health screening application form and pre-arrange boat or air travel to Anguilla. Quarantine/movement restrictions for seven to 14 days (depending on country of origin and vaccination status) and additional on-island testing are required; all travelers need health insurance valid in Anguilla.

Beginning July 1, 2021, fully vaccinated travelers will be able to visit Anguilla without having to pay fees, have travel health insurance or quarantine.

What's open: Anguilla has certified many resorts, restaurants and activities for Safe Environment use by tourists.

Anguilla is, once again, welcoming pre-approved travelers as of May 25, 2021, following a month-long suspension on all entries. Travelers must follow step-by-step instructions involving authorization, hotel and transfer reservations, and testing. However, with the reopening, quarantine time has been reduced to seven days for fully vaccinated travelers who are at least three weeks past their final dose, and that will be lifted as of July 1.

The government recommends starting the application process at least seven days before your intended travel date. All visitors seeking a short-term stay or a work-from-Anguilla arrangement need to seek a Travel Authorization (each individual traveler, including children, must get an authorization; the fee is $300 for an individual, plus $200 for any additional person on the application), provide proof of a negative COVID-19 PCR test taken three to five days (72-120 hours) before departure and then undergo a temperature check and take another test upon arrival.

For unvaccinated travelers, a third test on day 7 or 14 (depending on where the traveler is from) is also required. The U.S. is a high-prevalence country, so a 14-day stay in your resort "bubble" is required until the second on-island test results are received. Multigenerational families and/or groups with a mix of unvaccinated and vaccinated persons will all have to quarantine for a 10-day period, utilizing only approved short-stay services.

Guests must stay in place at their accommodations until receiving their second on-island test result or use Safe Environment-approved ground transportation to visit Safe Environment-certified restaurants or participate in Safe Environment-approved activities. See FAQs here .

Travel health insurance that covers COVID-19 and is valid in Anguilla is also required for unvaccinated travelers. In addition, travelers entering/transferring via Dutch St. Maarten must complete St. Maarten's health screening application form and prearrange boat or air travel to Anguilla.

Botswana , one of Africa's top safari destinations, is open to American tourists. A visa is not required, but the U.S. State Department's advisory for Botswana is Level 4: Do Not Travel.

The Centers for Disease Control and Prevention (CDC) has issued a Level 4 Travel Health Notice for Botswana due to COVID-19, indicating a very high level of COVID-19 in the country.

According to the U.S. Embassy in Botswana , limited commercial flights to Botswana are available through South Africa and Ethiopia and some charter flights to Kasane and Maun may be available (check with tour companies operating in Botswana). The U.S. banned travel from South Africa (for non-U.S. citizens or permanent residents) on Jan. 30, 2021, due to the COVID-19 variant circulating there, so flight schedules transiting through South Africa may be more limited or subject to change.

All passengers must present a negative COVID-19 PCR test taken within 72 hours of travel to Botswana; quarantine is not required.

All passengers must also present a negative COVID-19 PCR test taken within 72 hours of their departure from Botswana, which parallels a Jan. 26, U.S. requirement that everyone aged two and older traveling to the U.S. from Botswana must show a negative viral COVID-19 test result taken within 72 hours of departure before being allowed to board their flights. Details are available here .

Gaborone has a 10 p.m. to 4 a.m. curfew in place until further notice. Permits are required to travel between any of Botswana's nine zones and are restricted to essential travel. Tourism is considered essential, but additional COVID-19 testing may be required to travel between zones.

There are fines for non-compliance of Botswana's mask mandate and other restrictions.

Check the Johns Hopkins University website for updates on cases in Botswana.

Other restrictions: Passengers must complete a Traveler's Health Declaration form.

What's open: Most hotels and businesses; the Brazilian government has imposed very few restrictions.

Brazil has the third highest number of coronavirus cases in the world—and the second-highest number of deaths, after the United States—and throughout March and April 2021 experienced record-high surges in cases, topping 4,000 deaths in a single day, because of a troubling new COVID-19 variant that has caused many countries, including the U.S., to ban entry of travelers from Brazil.

Brazil lifted its own travel ban on foreigners at the end of July 2020 and tourists are welcome. However, the U.S. State Department has issued a Level 4: Do Not Travel advisory for Brazil and the U.S. Embassy in Brazil continues to recommend that all travelers who do choose to go to Brazil purchase insurance before departing the United States even though Brazil no longer requires proof of health insurance to enter the country.

Since December 2020, all travelers aged 12 and older arriving in Brazil by air, both tourists and residents, must present a negative COVID-19 PCR test result taken within 72 hours prior to boarding and complete a Traveler's Health Declaration form.

Brazilians are currently not allowed to travel to the U.S., which has also banned entry by foreign nationals who have been to Brazil in the past 14 days.

Ecuador is also now allowing travelers who have completed their COVID-19 vaccination and present a vaccination card to enter without testing; travelers who have documented proof of recovery from COVID-19 and are more than one month past the onset of symptom may also present that.

Note: There are special requirements for all travelers to the Galapagos Islands, where a negative COVID-19 test taken within 96 hours must be presented upon arrival. It can be the same test used to enter the country if it's a PCR test and is still within the required 96 hour timeframe for the Galapagos. To visit the Galapagos via transit through Quito or Guayaquil airports, vaccinated travelers need to present negative test results. The U.S.Embassy also says that travelers to the Galapagos need a "salvoconducto" from their tour operator, and should contact the operator directly for that document.

Airlines are now required to verify that all travelers traveling to Ecuador have a negative test result or proof of vaccination before allowing them to board.

Rapid Antigen testing may also be conducted upon arrival and if the test is positive the traveler will be required to isolate in a government shelter for 10 days. As long as a traveler has the negative PCR test result, doesn't display any symptoms upon arrival, and doesn't receive a positive test on a random rapid test at the airport, quarantine is not required.

Details can be found here . However, COVID-19 cases have been rising throughout April and May 2021, setting new weekly and monthly records.

In February 2021, the country announced that fully vaccinated U.S. travelers can visit, but as of March 25, 2021, both vaccinated and unvaccinated visitors can enter the country. They must obtain a Travel Health Authorization via the online portal, upload a negative result of a COVID-19 PCR test taken within 72 hours of their flight, submit their flight and hotel details and have valid travel health insurance that covers, at a minimum, COVID-19 related isolation, quarantine and clinical care.

South Africa re-opened to tourism on Oct. 1, 2020, and, according to the U.S. Embassy in South Africa , as of Nov. 11, 2020, U.S. citizens can enter the country for tourism purposes, but they need to present a negative COVID-19 test taken within 72 hours from the time of departure, or they must remain in mandatory quarantine for 10 days at their own cost. Details can be found here .

In December 2020, both South Africa and the United Kingdom began reporting troubling new COVID-19 variants, which resulted in the widespread suspension of flights and travel to and from both the U.K. and South Africa. The U.S. government on Jan. 26, 2021 then banned travel from South Africa , with the exceptions of U.S. citizens and legal U.S. residents (travel from the U.K. and Brazil, where another COVID-19 variant has emerged, had already been banned).

South Africa suffered a dangerous second wave in December 2020 and January 2021, surpassing 1.5 million total cases and forcing a return to a Level 3 lockdown alert with restrictions that were eased back to Level 1 on March 1, 2021 as cases declined. But an Adjusted Alert Level 2 was issued on May 31, 2021, with bars and restaurants required to close at 10 p.m.

All arriving travelers will face a health screening. If a passenger has a negative test result, they will not have to quarantine. Those who don't present test results will need to quarantine for 10 days at their own expense. Travelers must also download the South Africa coronavirus mobile tracing app , and fill in all the information on that app.

Americans can go to South Korea, but a mandatory two-week quarantine will make it undesirable for most travelers. Cases, which have been largely under control throughout the pandemic, have risen in May 2021.

While the country is technically open to foreigners on short-term visits, most (with limited exceptions) are subject to a mandatory quarantine at a government-designated facility at their own expense for 14 days. The U.S. Embassy in South Korea notes that this will cost approximately $100-$150 USD per night, and passengers will be required to sign a release form agreeing to these conditions before departing. As of Jan. 8, 2021 all travelers are also required to provide proof of a negative COVID-19 PCR test taken within 72 hours of departure; airlines will not permit passengers to board without the proper test results in their original form (English is acceptable). Additional details can be found here .

The U.S. Embassy also notes that access to medical care in the country may be limited and that "the Government of Tajikistan frequently adjusts its entry and exit requirements in response to the COVID-19 pandemic, and changes to policy are not immediately made available to the public." A non-expired visa is also required to leave Tajikistan.

The U.S. State Department has a Level 4: Do Not Travel advisory in effect for Tajikistan related to both COVID-19 and the potential for terrorism.

COVID-19 test required: Yes, as of May 3, 2021

Other restrictions: U.S. travelers need a tourist visa and must complete and online Health Surveillance Form within 24 hours of arrival; arriving passengers face enhanced screening and those from countries with new COVID-19 variants will be subjected to a rapid test, followed by a 14-day quarantine if they get a positive result.

Tanzania, which had been accepting tourists with no testing or quarantine conditions attached, now requires all travelers to present a negative COVID-19 PCR test result taken within 72 hours of arrival and to complete an online Health Surveillance Form within 24 hours prior to arrival. Travelers will undergo screening upon arrival and those arriving from countries with a high number of COVID-19 cases (or those who have been in those countries within the past 14 days) will also be required to take a rapid test ($25) upon arrival in Tanzania, and a positive result requires a 14-day quarantine at their own cost.

The new requirements were put into effect by the country's new president Samia Saluhu Hassan to try to curb the spread of new variants.

Tanzania's late president John Magufuli had until a few weeks before his death denied widespread COVID-19 transmission (the government had not been reporting cases). Magufuli, 61, died on March 18, 2021 after not being seen in public for more than two weeks.

The U.S. Embassy in Tanzania is reporting that it has seen an increase in the number of cases reported to it since January 2021 and that the use of masks, social distancing and other prevention strategies are largely absent throughout the country. The U.S. State Department's advisory for Tanzania is Level 4: Do Not Travel .

U.S. tourists also need a visa to visit Tanzania. See details here .

Tanzania has received much criticism on how it has handled the coronavirus pandemic. The government hasn't actively revealed data about infection rates or death. President Magufuli had said that releasing the data was "causing panic" and at the start of the pandemic declined to close churches, saying that the virus "cannot survive in the body of Christ — it will burn." He also claimed Tanzania was free of coronavirus as of June 2020 due to prayer and the work of front-line workers. He even celebrated citizens who weren't wearing masks as a sign that people were no longer afraid and the virus was gone.

The U.S. State Department's advisory for Zimbabwe is Level 2: Exercise Increased Caution .

Check the Johns Hopkins University website for updates on cases in Zimbabwe.

Important caveats and things to know

COVID-19 continues to spread around the world. While some countries have done a good job of containing the virus, there is still much we don't know. Travel is still considered a risky undertaking, especially for non-vaccinated individuals. Know the rules and regulations for the place you are planning to visit and make sure you have completed all the necessary steps (like pre-departure testing in most cases). There is also the possibility countries could change their minds on reopening at the last minute (like we saw in Portugal and Iceland , which has since opened up to vaccinated Americans) so make sure you are booking refundable tickets and hotels or purchasing travel insurance.

What about Europe?

Most of the E.U. is still closed to Americans, but countries are reopening on a weekly basis, mostly to fully vaccinated travelers (the latest are France and Spain) and leadership of the European Union recently indicated that vaccinated Americans will be welcome within the E.U. this summer. Currently, Croatia, Greece and Italy have reopened to Americans and Americans can go to the U.K., but a 10-day required quarantine and restrictions on internal travel make the prospect less than ideal. The lifting of some U.K. restrictions, however, could just be weeks away.

• TSA PreCheck
• Mobile Passport Control Opens another site in a new window that may not meet accessibility guidelines

Travel documents and requirements

You’re responsible to make sure you have the correct documents to enter and pass through any countries during your trip, and then make your way back home. If you don’t have the required documentation and identification, you will not be allowed to board the plane and would be responsible for any resulting costs.

Keep in mind:

• Everyone traveling, regardless of age, needs their own set of travel documents.
• Always use the information exactly as it appears on your passport (to book and fill out any documents).
• Check with the consulate of every country you’re entering (or passing through) to make sure you meet all travel requirements.
• Some countries require proof of return or onward travel, a visiting address and sufficient funds for your stay.

All children, regardless of age, must have a passport and any travel documents required by the countries visited. If you’re traveling internationally with anyone under 18, you may be required to show documentary evidence of your relationship and a Letter of Consent or permission for the child's travel from the parent(s) or legal guardian not present.

Traveling with children

A passport is required for all international travel. If you're traveling anywhere overseas, you need a passport to board an international flight and to enter the country. Passport cards will not be accepted as form of I.D. for international air travel.

• Some countries require your passport to be issued at least 6 months before the day you arrive. Check your destination’s requirements if you’re unsure.
• Passports must be kept in good condition, free of any damage beyond normal wear and tear, and material alterations. You may be denied boarding if you travel with a passport that appears damaged or altered.

U.S. citizens can use any government-issued form of identification to travel between the U.S., Puerto Rico and the U.S. Virgin Islands.

In addition to a passport, some countries require a visa to enter. If you’re traveling to the U.S. for a stay less than 90 days, the Department of Homeland Security requires eligible travelers to use the Electronic System for Travel Authorization (ESTA), as part of the Visa Waiver Program (VWP). You must submit your application no later than 72 hours before departing for the U.S., but we suggest you apply for authorization when you start planning your trip. You will be denied boarding if you arrive at the airport without an approved ESTA.

An approved ESTA travel authorization is:

• Valid for up to 2 years or your passport expires, whichever comes first
• Valid for multiple entries into the U.S.
• Not a guarantee of admissibility to the U.S., approval only authorizes you to board a carrier for travel to the U.S.

To enter the U.S. under the VWP, each passenger must have a machine-readable passport. If you don’t have a machine-readable zone, a valid visa is required.

Each passenger traveling to the U.S. under the VWP must have a:

• Valid electronic (e-Passport) with this symbol on the passport cover

If you present a non-electronic passport, a valid U.S. visa will be required or you’ll be denied boarding and entry into the U.S.
