Yellow fever vaccination is not recommended for routine travel to this destination. Talk to a travel health provider at least four to six weeks before departure to make sure you have time for any vaccines that require multiple doses.

Is the tap water safe to drink in Antigua and Barbuda?

Tap water in Antigua and Barbuda is treated and government-distributed, and it is generally described as safe to drink. However, some travelers experience mild stomach upset on arrival as their system adjusts to local water. If you have a sensitive stomach, switching to bottled or sealed water during your stay is a practical precaution.

Health Risks in Antigua and Barbuda

Antigua and Barbuda is a low-risk destination overall, but there are several health considerations worth knowing before you travel. The main risks fall into four categories: vaccine-preventable diseases, mosquito-borne illness, food- and water-related illness, and weather-related disruption.

Vaccine-Preventable Diseases

Several diseases that are preventable by vaccination are present in or relevant to travel in Antigua and Barbuda. According to the CDC, hepatitis A (a liver infection spread through contaminated food or water), hepatitis B (a liver infection transmitted through blood, sexual contact, or medical procedures), and typhoid (a bacterial infection spread through contaminated food and water) all pose a risk to unvaccinated travelers. The CDC also notes a current global measles alert affecting international travelers, meaning anyone who is not fully vaccinated against measles faces a real risk when traveling internationally, including to this destination. The good news is that all of these diseases are preventable — vaccines exist for each of them, and getting vaccinated before you leave is the single most effective step you can take.

Mosquito-Borne Illness

Mosquito-borne illness is a genuine consideration in Antigua and Barbuda's tropical climate. The WHO recommends preventing mosquito bites at all times during your visit, not just at dawn and dusk. Zika virus (a viral infection spread by mosquito bites that can cause serious complications during pregnancy) is among the infections of concern, and the WHO advises that pregnant travelers and those planning to conceive take extra precautions, including discussing sexual transmission risk with their healthcare provider. To reduce your exposure, use an EPA-registered insect repellent containing DEET, picaridin, or IR3535, wear light-colored long-sleeved clothing when outdoors, and choose accommodation with air conditioning or window screens where possible.

Rabies Risk

Rabies (a fatal viral disease transmitted through the bite or scratch of an infected animal) is present in some parts of the Caribbean, but according to the CDC, dogs infected with rabies are not commonly found in Antigua and Barbuda. The risk is low for most travelers. However, the CDC notes that access to rabies treatment after exposure may be limited outside larger urban medical facilities on the island. If your trip involves significant contact with animals — for example, if you are a veterinarian, wildlife researcher, or plan to spend extended time in rural areas — a pre-exposure rabies vaccine may be worth discussing with a travel health provider.

Hurricane and Severe Weather Risk

Antigua and Barbuda sits in an active hurricane zone. The WHO notes that severe weather events regularly affect the islands and can disrupt transport, power, water supply, and access to medical services. Hurricane season runs from June through November. If you are traveling during this period, monitor weather forecasts closely, purchase comprehensive travel insurance that covers weather-related disruption, and know the emergency contact details for your accommodation and the nearest medical facility before you arrive.

Recommended Vaccinations for Antigua and Barbuda

According to the CDC, several vaccines are recommended for travel to Antigua and Barbuda — and making sure you are protected before you leave is one of the most important things you can do for your health on this trip.

• Hepatitis A vaccine: Protects against hepatitis A, a liver infection spread through contaminated food and water. According to the CDC, this vaccine is recommended for all unvaccinated travelers aged one year and older, and infants aged six to eleven months should also receive a dose before travel. Get the first dose at least two weeks before departure for maximum protection.
• Hepatitis B vaccine: Protects against hepatitis B, a liver infection transmitted through blood, sexual contact, or unsterilized medical equipment. According to the CDC, this vaccine is recommended for unvaccinated travelers of all ages going to Antigua and Barbuda. The standard series requires three doses over six months, so plan ahead — an accelerated schedule may be available if your trip is sooner.
• Typhoid vaccine: Protects against typhoid fever, a serious bacterial infection spread through contaminated food and water. The CDC recommends this vaccine for most travelers, especially those visiting smaller towns or rural areas or staying with friends or relatives. Aim to complete vaccination at least two weeks before travel.
• MMR vaccine (measles, mumps, and rubella): Protects against three viral infections, including measles, which is currently circulating at elevated levels globally. According to the CDC, all international travelers who are not already fully vaccinated should receive this vaccine. If you are unsure of your vaccination history, a blood test can confirm immunity.
• Routine vaccines: The CDC recommends that all travelers have up-to-date routine vaccinations before any international trip. These include chickenpox (varicella), diphtheria-tetanus-pertussis (protection against three bacterial infections), influenza, polio, and shingles as age-appropriate. Check your records before you travel.
• COVID-19 vaccine: According to the CDC, all eligible travelers should be up to date with their COVID-19 vaccination before international travel.
• Rabies pre-exposure vaccine: The CDC recommends this vaccine only for selected travelers with a higher likelihood of animal exposure or those who may have difficulty accessing prompt post-exposure treatment. Discuss this with your travel health provider based on your specific itinerary.
• Yellow fever vaccine: According to the CDC, the yellow fever vaccine is not recommended for routine travel to Antigua and Barbuda. However, if you are arriving from a country where yellow fever transmission is a risk, proof of yellow fever vaccination may be required for entry. This requirement does not apply to travelers arriving directly from the United States.

Your personal vaccine needs depend on your age, health history, previous vaccinations, and the specific activities you plan to do in Antigua and Barbuda. Visit a travel health clinic or your healthcare provider at least four to six weeks before departure to get a plan that is right for you.

Tap Water and Food Safety in Antigua and Barbuda

Tap water in Antigua and Barbuda is treated and government-distributed, and it is generally considered safe to drink — but there are a few practical things worth knowing before you arrive.

Water Safety

According to the WHO, tap water on the island is treated and described as potable (safe for drinking) by government standards. The water supply is chlorinated, which controls most harmful pathogens. That said, some travelers — particularly those arriving from different water systems — experience mild stomach upset in the first few days as their body adjusts to local water. If you have a history of a sensitive stomach or gastrointestinal issues, switching to bottled or sealed drinking water for your stay is a straightforward way to avoid this. When ordering drinks, check that ice is made from treated water, which is standard at most hotels and restaurants but worth confirming at smaller local establishments. If you are hiking or spending time in remote areas, carry a water purification option such as a filter bottle or purification tablets as a backup.

Food Safety

Antigua and Barbuda has a thriving food culture, and eating well is one of the great pleasures of any visit. Most food at established restaurants and resorts is prepared to a high standard. To keep your stomach happy, follow a few simple rules. Choose freshly cooked, hot food over dishes that have been sitting out. Eat fruit that you can peel yourself, such as bananas or mangoes, rather than pre-cut fruit from street stalls where hygiene is harder to assess. Avoid raw shellfish and undercooked seafood, which can carry bacteria regardless of the destination. Wash your hands before eating, or use an alcohol-based hand sanitizer when soap and water are not available. Street food is a wonderful way to experience local culture — just look for stalls that are busy, where food is cooked to order and served hot.

Common Traveler Illnesses in Antigua and Barbuda

Most visitors to Antigua and Barbuda have a healthy, trouble-free trip. The illnesses that do affect travelers here are largely preventable, and knowing what to watch for means you can act quickly if symptoms appear.

Traveler's Diarrhea

Traveler's diarrhea (loose stools and stomach cramps caused by consuming food or water contaminated with bacteria, viruses, or parasites) is one of the most common illnesses affecting visitors to any tropical destination, including Antigua and Barbuda. Symptoms typically include frequent loose stools, nausea, and stomach cramps, usually starting within the first few days of arrival. To prevent it, stick to the food and water safety habits described in the previous section. If symptoms do develop, stay well hydrated with bottled water or an oral rehydration solution (a drink containing salts and sugars that help your body absorb fluids). Most cases resolve on their own within a few days. Seek medical care if you develop a high fever, blood in your stools, or symptoms that do not improve after 48 hours.

Measles

Measles (a highly contagious viral infection that spreads through the air and causes fever, rash, and respiratory symptoms) is a concern for any unvaccinated traveler right now because global transmission rates are rising. According to the CDC, international travel is one of the primary ways measles spreads to new communities. Symptoms include high fever, cough, runny nose, red eyes, and a distinctive red rash that spreads from the face downward. The most effective prevention is full vaccination with the MMR vaccine before you travel. If you develop a fever and rash during or after your trip, contact a healthcare provider promptly and mention your recent travel history.

Mosquito-Borne Illness Including Zika

Beyond prevention, it is worth knowing what to watch for if you have been exposed to mosquitoes during your trip. Zika virus (a viral infection spread by mosquito bites that can cause mild symptoms in most adults but serious birth defects if contracted during pregnancy) may cause fever, rash, joint pain, and red eyes. Symptoms are often mild and may be mistaken for a minor illness. If you are pregnant or planning to become pregnant and you develop any of these symptoms after returning home, contact your healthcare provider immediately and mention your travel to Antigua and Barbuda. According to the WHO, sexual transmission of Zika is also possible, so follow guidance on precautions for the appropriate period after your return.

Mild Water Acclimatization Symptoms

Some travelers notice mild abdominal discomfort or loose stools in the first one to two days after arrival, even when they have not eaten anything obviously risky. This is often linked to the body adjusting to a new local water supply rather than a true infection. Staying hydrated, eating lightly on your first day, and allowing your digestive system to settle usually resolves this quickly. If symptoms persist beyond two days or worsen, treat it as you would traveler's diarrhea and seek medical advice if needed.

Visa Requirements for US Citizens Visiting Antigua and Barbuda

US citizens do not need a visa to enter Antigua and Barbuda. Entry for tourism and business is granted on arrival without any prior visa application.

You may stay for up to 90 days under this visa-free arrangement. To enter, you must hold a US passport that is valid for at least 180 days beyond your planned departure date from Antigua and Barbuda — check your passport expiry before you book your flights. You will also typically need to show proof of onward travel, such as a return ticket, and may be asked to demonstrate that you have sufficient funds for your stay.

There is no visa fee for US citizens entering under the standard tourist arrangement. If you plan to stay longer than 90 days or are traveling for purposes other than tourism or business, you should contact the Antigua and Barbuda High Commission or Embassy before your trip for guidance on the appropriate entry category.

Entry requirements can change. Always verify the latest requirements with official government sources — such as the Antigua and Barbuda government website and the US Department of State — before you travel, particularly if your plans change close to your departure date.
