Frequently Asked Questions

No FAQ questions were provided in the keyword brief. The section below draws on the most common questions travelers ask about visiting Palau, based on the research summary and destination context.

Is Palau safe to visit?

Yes, Palau is generally considered a safe destination. Official advisories describe it as low-risk from a security standpoint, and the CDC has not issued a Palau-specific health alert. You will still want to prepare for manageable health considerations like mosquito protection and safe food and water choices — but none of these should stop you from going.

Do I need any vaccinations to visit Palau?

No vaccinations are legally required for entry into Palau, but several are strongly recommended by the CDC to protect your health while you are there. According to the CDC, hepatitis A, hepatitis B, and typhoid vaccines are among the most important to discuss with your doctor before departure. Making sure your routine vaccines are current is equally important.

Is the tap water safe to drink in Palau?

No, tap water is not safe to drink in Palau. The Republic of Palau Ministry of Health and Human Services specifically states that tap water in Koror and Airai is not potable. Stick to sealed bottled water throughout your trip, and use it for brushing your teeth as well.

Do US citizens need a visa to visit Palau?

No, US citizens do not need a visa arranged in advance to visit Palau. You can stay for up to 30 days, and border officials issue a tourist visa on arrival. You will need a valid passport and proof of onward or return travel, and you must complete the Palau Entry Form within 72 hours before your departure.

What mosquito-borne diseases are a risk in Palau?

Dengue fever (a flu-like illness spread by daytime-biting mosquitoes) is the primary mosquito-borne concern in Palau. The WHO highlights mosquito-bite prevention as an important part of staying healthy during travel in the region. Wearing long sleeves, using EPA-registered insect repellent, and staying in accommodations with screens or air conditioning are your best defenses.

Get Your Personalized Travel Health Plan for Palau

Palau sits in a tropical Pacific setting where mosquito-borne illness like dengue and food- and water-borne infections like hepatitis A and typhoid are real considerations for anyone visiting without the right preparation. Tap water is not safe to drink in key areas including Koror and Airai, and several vaccines are recommended by the CDC before you travel. Your health needs are specific to your itinerary, your health history, and how you plan to spend your time on the islands — a personalized plan makes all the difference.

Health Risks in Palau

Palau carries a medium overall health risk for travelers. The main concerns are mosquito-borne illness, food- and water-borne infections, and a few vaccine-preventable diseases — all of which you can significantly reduce with the right preparation before and during your trip.

Mosquito-Borne Illness

Dengue fever (a viral illness that causes high fever, severe headache, joint pain, and rash, spread by the bite of infected Aedes mosquitoes) is the primary mosquito-borne concern in Palau. Unlike malaria-carrying mosquitoes, the Aedes mosquito bites primarily during daylight hours, so protection during the day is just as important as at night. The WHO emphasizes mosquito-bite prevention as a key part of staying healthy in Palau. Use an EPA-registered insect repellent containing DEET, picaridin, or oil of lemon eucalyptus every time you go outside. Wear long-sleeved shirts and long pants when possible, and choose accommodations with window screens or air conditioning. Risk is present year-round in tropical island settings like Palau.

Hepatitis A and Typhoid

Hepatitis A (a liver infection caused by a virus spread through contaminated food or water) and typhoid (a bacterial infection also spread through contaminated food and water, causing prolonged fever and digestive symptoms) are both meaningful risks in Palau, particularly if you plan to eat at local establishments, visit rural areas, or stay with local families. According to the CDC, both infections are vaccine-preventable and vaccination is recommended for most travelers to Palau. Beyond vaccination, washing your hands thoroughly before eating, avoiding raw or undercooked food, and drinking only sealed bottled water are practical steps that reduce your risk every day.

Hepatitis B

Hepatitis B (a viral liver infection spread through blood, sexual contact, or contaminated medical equipment) is endemic in Palau, meaning it circulates at higher background rates in the local population than in the United States. According to the CDC, hepatitis B vaccination is recommended for unvaccinated travelers of all ages heading to Palau. If you are not already vaccinated, talk to your doctor about starting the series as early as possible before your departure date, since the full course takes time to complete.

Measles

Measles (a highly contagious viral illness causing fever, cough, runny nose, and a distinctive rash) is a global travel concern right now. According to the CDC, rising measles activity worldwide has prompted a Level 1 travel notice covering international destinations including Palau. If you were born after 1957 and have not had two doses of the MMR vaccine (a combined measles, mumps, and rubella shot), confirm your status with your doctor before you fly. This is especially important if you are traveling with young children.

Rabies Exposure Risk

Rabies (a fatal viral disease of the nervous system transmitted through the bite or scratch of an infected animal) is a lower-level concern in Palau compared to many destinations, because dogs infected with rabies are not commonly found there. However, animal bites can still occur, and according to the CDC, access to rabies post-exposure treatment (the injections given after a potential exposure) may be limited outside larger urban or suburban medical facilities in Palau. If you plan to spend time in remote areas, work with animals, or travel with children who may approach animals, discuss rabies pre-exposure vaccination with your doctor before departure.

Recommended Vaccinations for Palau

According to the CDC, several vaccines are recommended before traveling to Palau. The exact vaccines you need depend on your personal health history, your age, and what you plan to do on your trip — but the list below covers what most travelers should discuss with their doctor or a travel health clinic.

• 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 unvaccinated travelers aged one year and older going to Palau, with a dose also recommended for infants aged six to eleven months before travel. Get your first dose at least two weeks before departure; a second dose six to twelve months later provides long-term protection.
• Hepatitis B vaccine: Protects against hepatitis B, a viral liver infection that is endemic in Palau. According to the CDC, this vaccine is recommended for unvaccinated travelers of all ages. The standard series requires multiple doses over several weeks or months, so start the conversation with your doctor early.
• Typhoid vaccine: Protects against typhoid fever, a serious bacterial illness spread through contaminated food and water. According to the CDC, this vaccine is recommended for most travelers to Palau, especially those visiting rural areas or staying with local families. Get vaccinated at least two weeks before your trip for the injectable form, or complete the full oral course before departure.
• MMR vaccine (measles, mumps, rubella): Protects against three viral illnesses, with measles being the most relevant given current global travel conditions. According to the CDC, all international travelers who are not fully vaccinated against measles should receive this vaccine, including an early dose for infants aged six to eleven months. Confirm your vaccination history before booking your flights.
• Routine vaccines: These include varicella (chickenpox), DTaP or Tdap or Td (diphtheria, tetanus, and pertussis), influenza (seasonal flu), polio, and shingles, as appropriate for your age. According to the CDC, all routine vaccines should be up to date before any international travel.
• COVID-19 vaccine: According to the CDC, all eligible travelers should be up to date with COVID-19 vaccination before international travel. Check your booster status before your departure date.
• Rabies pre-exposure vaccine: Protects against rabies by making post-exposure treatment simpler and more effective if you are bitten. According to the CDC, this vaccine is not routinely recommended for all travelers to Palau but should be considered if you have a higher risk of animal exposure or limited access to prompt medical care during your trip. The pre-exposure series requires three doses over several weeks.

This list is a starting point, not a prescription. Your personal health history, any medications you take, and your specific itinerary in Palau all affect which vaccines are right for you. See a travel health provider or clinic ideally four to six weeks before your departure to get a plan tailored to your trip.

Tap Water and Food Safety in Palau

Tap water is not safe to drink in Palau. This is not a precautionary statement — it is a direct warning from the Republic of Palau Ministry of Health and Human Services, which states that tap water in Koror and Airai is not potable. US travel guidance also confirms that tap water is not safe to drink in many areas across the islands. Plan accordingly from the moment you arrive.

Water Safety

Drink only sealed, commercially bottled water throughout your trip. Use bottled water for brushing your teeth as well — it is an easy habit to forget and an easy way to get sick. If bottled water is unavailable, boiling water is the safest alternative supported by Palau's own health ministry guidance. Boil water for at least one minute before drinking or using it to rinse your mouth. Avoid ice in drinks unless you are confident it was made from purified or bottled water, which is difficult to verify at smaller establishments. Water purification tablets or a portable filter certified to remove bacteria and protozoa (tiny parasites) can serve as a useful backup if you are traveling to more remote areas of the archipelago.

Food Safety

Food safety in Palau follows the same principles that apply across tropical destinations. Eat food that is freshly cooked and served hot. Avoid raw or undercooked meat, seafood, and eggs. Raw salads and cut fruit washed in tap water carry risk, so choose cooked vegetables or fruit you peel yourself. Street food can be delicious and generally safe when it is cooked to order in front of you at a busy stall with high turnover — a crowd is usually a good sign. Avoid food that has been sitting out at room temperature for an extended period, particularly in warm outdoor settings. Wash your hands with soap and water before every meal, or use an alcohol-based hand sanitizer containing at least 60 percent alcohol when handwashing is not possible.

Common Traveler Illnesses in Palau

The illnesses that most commonly affect travelers in Palau fall into two broad categories: gastrointestinal (digestive system) illnesses from unsafe food and water, and mosquito-borne infections. Knowing what to watch for helps you act quickly if something feels off.

Traveler's Diarrhea

Traveler's diarrhea is a digestive illness caused by bacteria, viruses, or parasites (tiny organisms) in contaminated food or water, producing loose stools, stomach cramps, nausea, and sometimes fever. It is the most common illness affecting travelers in destinations with food and water safety concerns like Palau. If you develop symptoms, stay well hydrated with bottled water or an oral rehydration solution (a drink that replaces fluids and salts lost through diarrhea). Mild cases typically resolve within a few days. Seek medical care if you have a high fever, blood in your stool, or symptoms that worsen or do not improve after 48 hours. Talk to your doctor before your trip about whether to pack a prescription antibiotic for self-treatment in case of moderate to severe symptoms.

Dengue Fever

Dengue fever causes sudden high fever, intense headache, pain behind the eyes, muscle and joint aches, and a rash that appears a few days after fever onset. There is no specific antiviral treatment for dengue — care focuses on rest, fluids, and fever management with acetaminophen (do not use ibuprofen or aspirin, as these can increase bleeding risk with dengue). If you develop a high fever within two weeks of returning from Palau, tell your doctor where you traveled so they can test for dengue. Seek emergency care immediately if you experience severe abdominal pain, persistent vomiting, or bleeding from the gums or nose, as these can signal a more serious form of the illness.

Measles

Measles starts with fever, cough, runny nose, and red eyes before a blotchy red rash spreads from the face downward across the body. It spreads through the air and is extremely contagious — you can catch it simply by being in the same room as someone who is infected. There is no specific treatment; care is supportive. If you develop these symptoms after international travel, call your doctor before going in person so they can prepare to receive you without exposing other patients in the waiting room.

Animal-Bite Injuries and Rabies Risk

An animal bite or deep scratch — most often from a dog or bat — requires prompt medical attention regardless of where it happens. If you are bitten or scratched in Palau, wash the wound thoroughly with soap and running water for at least 15 minutes immediately after the incident. Then seek medical care as quickly as possible. Post-exposure treatment (a series of injections that prevents rabies from developing) is highly effective when started promptly, but access to this treatment may be limited outside larger medical facilities in Palau. Do not wait to see if symptoms develop — by the time rabies symptoms appear, treatment is no longer effective.

Visa Requirements for US Citizens Visiting Palau

US citizens do not need a visa to visit Palau. Entry is straightforward, and you can stay for up to 30 days without arranging anything in advance.

When you arrive, border officials issue a 30-day tourist visa on arrival at no pre-arranged cost. You do not need to visit an embassy or apply online before your trip. However, there are a few requirements you must meet to enter smoothly. Your passport must be valid for at least six months from your date of entry — check the expiration date well before you travel and renew early if needed. You must also show proof of return or onward travel, meaning a booked flight out of Palau, so have that confirmation accessible when you arrive.

One additional step is required before you fly: you must complete the Palau Entry Form no more than 72 hours before your departure. This generates a QR code that you will need at check-in and upon arrival. Complete this step in the days just before your outbound flight so the QR code is ready when you need it.

Visa policies can change. Always verify current entry requirements directly with the Palau Bureau of Immigration or the US Department of State before your travel date, as official requirements take precedence over any third-party source including this page.
