Frequently Asked Questions

Is Uruguay safe to visit?

Uruguay is generally considered one of the safer destinations in South America, with a relatively low traveler health risk profile. The US Department of State advises exercising increased caution in certain areas, particularly tourist zones and poorly lit locations at night. Staying aware of your surroundings and taking standard urban precautions will go a long way toward keeping your trip trouble-free.

Do I need any vaccinations to travel to Uruguay?

Yes, several vaccinations are recommended before you travel to Uruguay. According to the CDC, all international travelers should be fully up to date on routine vaccines, and the measles-mumps-rubella (MMR) vaccine is specifically emphasized for international travel. Hepatitis A and Typhoid vaccines are also recommended for most visitors, and yellow fever vaccination may be required depending on your travel history and entry circumstances.

Is the tap water safe to drink in Uruguay?

Tap water in Uruguay is generally safe to drink, and the country has near-universal access to reliable drinking water. During the 2023 water crisis in Montevideo, the government confirmed water remained potable but advised certain groups — including pregnant women and people with high blood pressure or kidney disease — to use bottled water due to elevated sodium levels. Outside of active advisories, tap water is a reasonable choice for most healthy travelers.

Are there mosquitoes in Uruguay?

Yes, mosquitoes are present in Uruguay and can transmit illnesses including dengue and Zika virus. The risk is real but manageable. Using an EPA-registered insect repellent, wearing long sleeves and pants during peak mosquito hours, and staying in accommodations with screens or air conditioning are effective ways to reduce your exposure.

What is the currency in Uruguay and do I need travel insurance?

The currency in Uruguay is the Uruguayan Peso (UYU). Travel insurance that includes medical coverage is strongly recommended for any international trip, including Uruguay. If you need medical care while abroad, having insurance ensures you can access treatment without facing unexpected out-of-pocket costs.

Health Risks in Uruguay

Uruguay carries a low overall health risk for travelers, but a handful of specific concerns are worth knowing before you go. Mosquito-borne diseases, a parasitic infection spread by insects, and occasional water quality disruptions are the primary risks to prepare for.

Mosquito-Borne Diseases

Dengue is the most significant mosquito-borne illness risk in Uruguay. Dengue (a viral illness that causes fever, severe headache, joint pain, and rash) is transmitted through the bite of an infected Aedes mosquito. The WHO notes dengue as a relevant risk for travelers to Uruguay. To reduce your exposure, apply an EPA-registered insect repellent containing DEET, picaridin, or IR3535 to exposed skin whenever you are outdoors. Wear long-sleeved shirts and long pants, especially during dawn and dusk when mosquitoes are most active. Stay in accommodations with window screens or air conditioning where possible.

Zika virus (a mosquito-borne infection that can cause mild fever, rash, and joint pain in most people but poses serious risks to developing fetuses) is also identified as a possible risk in Uruguay. If you are pregnant or planning to become pregnant, speak with your doctor before traveling. The WHO recommends pregnant travelers discuss Zika risk with a healthcare provider before visiting any destination where the virus is present.

Chagas Disease

Chagas disease (a parasitic infection caused by Trypanosoma cruzi, spread through the bite of infected triatomine bugs, also called "kissing bugs") is a recognized risk in Uruguay, according to the WHO. These insects typically live in cracks and crevices in rural or poorly constructed buildings. If you are staying in well-maintained urban hotels, your risk is low. If your itinerary includes rural areas or rustic accommodation, inspect your sleeping area, use bed nets, and avoid sleeping in mud or thatch-roofed structures without protection.

Animal Exposure and Rabies

Rabies (a fatal viral disease transmitted through the saliva of infected animals, usually via a bite or scratch) is a consideration for some travelers depending on planned activities. According to the CDC, travelers who may have contact with wild animals, stray dogs, or bats — or who will be in remote areas far from medical care — should discuss the rabies vaccine with a travel health provider before departure. If you are bitten or scratched by any animal in Uruguay, seek medical attention immediately regardless of vaccination status.

Water Quality During Supply Disruptions

Uruguay's water infrastructure is among the most reliable in South America. However, during periods of drought or water system stress — such as Montevideo's 2023 water crisis — quality can be affected. The Uruguayan government confirmed water remained potable during that event, but elevated sodium levels prompted caution for specific groups. Monitor local news and government advisories during your stay, and switch to bottled water if any public health notice is issued.

Urban Safety and Personal Wellbeing

Your physical safety directly affects your health and travel experience. The US Department of State advises exercising increased caution in Uruguay, particularly in tourist areas and poorly lit locations. Petty theft is the most common concern. Keep valuables secured, avoid displaying expensive items, and use reputable transportation options, especially at night.

Recommended Vaccinations for Uruguay

Most travelers to Uruguay need to update their routine vaccines and add a few destination-specific ones. According to the CDC, being fully vaccinated before international travel is one of the most effective ways to protect your health abroad.

• Routine Vaccines — These include vaccines you may have received in childhood, such as tetanus-diphtheria-pertussis, varicella (chickenpox), and annual influenza. According to the CDC, all routine vaccines should be up to date before any international trip. Check with your doctor at least four to six weeks before departure to confirm your status.
• MMR (Measles-Mumps-Rubella) — This vaccine protects against measles (a highly contagious viral illness that can cause serious complications), mumps, and rubella. According to the CDC, all international travelers should be fully vaccinated with the MMR vaccine before travel. If you are unsure of your vaccination history, a booster dose is a straightforward precaution.
• Hepatitis A — Hepatitis A (a liver infection spread through contaminated food or water) is recommended for most travelers to Uruguay by the CDC. Get this vaccine at least two weeks before departure; a single dose provides strong short-term protection, and a second dose given six to twelve months later provides long-term immunity.
• Typhoid — Typhoid (a bacterial infection spread through contaminated food and water that causes prolonged fever and gastrointestinal illness) is listed by the CDC and WHO as a recommended vaccine for travel to Uruguay. The injectable form should be given at least two weeks before travel; an oral option is also available.
• Hepatitis B — Hepatitis B (a viral liver infection spread through blood, sexual contact, or contaminated medical equipment) is recommended for some travelers depending on planned activities, length of stay, and potential medical exposure. According to the CDC, travelers who may receive medical or dental care abroad, or who may have new sexual partners, should consider this vaccine. The standard series requires three doses over six months, so plan ahead.
• COVID-19 — The CDC recommends that travelers be up to date on their COVID-19 vaccination before international travel. Staying current with any recommended boosters is the most straightforward step you can take.
• Rabies — The rabies vaccine (a pre-exposure series that does not eliminate the need for post-exposure treatment but significantly simplifies it) may be appropriate if your itinerary involves significant animal contact, outdoor adventure activities, or time in remote areas. According to the CDC, discuss this with a travel health provider based on your specific plans.
• Yellow Fever — Yellow fever (a viral hemorrhagic illness transmitted by mosquitoes, endemic to parts of Africa and South America) vaccination may be required for entry into Uruguay if you are arriving from a yellow fever risk country. According to the CDC, verify the exact entry conditions based on your travel history before departure, as requirements can change.
• Polio — Polio (a viral disease that can cause paralysis) vaccination is listed by the CDC and WHO for travel to Uruguay. Most adults vaccinated in childhood are protected, but a one-time adult booster may be recommended depending on your history.

Your vaccine needs depend on your personal health history, age, pregnancy status, and the specific activities you have planned. Consult a travel health clinic or your healthcare provider at least four to six weeks before your departure date to get personalized guidance.

Tap Water and Food Safety in Uruguay

Tap water in Uruguay is generally safe to drink — this is one of the few South American countries where you can turn on the tap with confidence under normal conditions.

Water Safety

Uruguay has near-universal access to treated drinking water, and the WHO recognizes the country's water quality as highly reliable under standard conditions. In most cities and towns, tap water is safe for drinking, brushing teeth, and making ice. The main exception to keep in mind is during drought conditions or supply disruptions. During Montevideo's 2023 water crisis, the government confirmed water was still potable but flagged elevated sodium levels as a concern for people with high blood pressure, kidney disease, heart failure, or cirrhosis, and for pregnant women. If you fall into any of these categories, or if a local advisory is issued during your visit, switch to commercially bottled water. Outside of any active advisory, bottled water remains a perfectly reasonable choice if you simply prefer it. Avoid drinking from rivers, streams, or any untreated natural water source.

Food Safety

Uruguay's food scene is a genuine highlight of any visit, and the overall food safety standards in urban areas are solid. Eat at busy, well-patronized restaurants and food stalls — high turnover means fresher ingredients. Cooked foods served hot are your safest bet. Be more cautious with raw shellfish, as it can carry bacteria or viruses regardless of the country. Fresh fruits and vegetables are generally fine when washed with clean tap water or peeled yourself. Avoid pre-cut fruit sold at street stalls if you are unsure how it was prepared. Dairy products are widely pasteurized in Uruguay, so standard dairy items from established vendors are safe. Stay hydrated — Uruguay's summer months can be warm, and dehydration is one of the most common and preventable traveler complaints.

Common Traveler Illnesses in Uruguay

The illnesses most likely to affect your trip to Uruguay are manageable with the right preparation. Knowing the symptoms and when to act is your best defense.

Dengue Fever

Dengue fever (a mosquito-borne viral illness) is the most notable infectious disease risk for visitors to Uruguay, as noted by the WHO. Symptoms typically appear four to ten days after a mosquito bite and include sudden high fever, severe headache, pain behind the eyes, muscle and joint pain, nausea, and a skin rash. There is no specific antiviral treatment for dengue — rest, fluids, and acetaminophen (paracetamol) for fever management are the standard approach. Do not take ibuprofen or aspirin if you suspect dengue, as these can increase bleeding risk. Seek medical care promptly if your fever is very high, you develop severe abdominal pain, or you notice any bleeding from the nose or gums.

Zika Virus

Zika virus (a mosquito-borne infection in the same family as dengue) causes mild symptoms in most adults — low-grade fever, rash, joint pain, and red eyes — that resolve within a week. The serious concern is for pregnant travelers, as Zika infection during pregnancy is linked to birth defects including microcephaly (abnormally small head size in newborns). If you are pregnant, discuss your travel plans with your OB or midwife before booking. If you develop a rash or fever after returning home, let your doctor know you traveled to Uruguay so they can test appropriately.

Traveler's Diarrhea

Traveler's diarrhea (loose, frequent stools caused by consuming food or water contaminated with bacteria, viruses, or parasites) can occur even in destinations with good overall food safety standards. Symptoms include sudden onset of loose stools, stomach cramps, nausea, and occasionally vomiting. Stay well hydrated using oral rehydration salts (electrolyte packets you dissolve in water) if symptoms develop. Mild cases typically resolve within one to two days. If diarrhea is severe, bloody, or accompanied by a high fever, seek medical care rather than waiting it out.

Sodium-Related Health Effects from Water

During periods of water system stress — as experienced in Montevideo in 2023 — elevated sodium in tap water can cause health effects for people with certain conditions. High sodium intake can worsen high blood pressure (hypertension), aggravate heart failure or kidney disease, and is not recommended for pregnant women. If you have any of these conditions and are visiting during a water advisory, use bottled water for drinking and cooking throughout your stay.

Visa Requirements for US Citizens Visiting Uruguay

US citizens do not need a visa to visit Uruguay for stays of up to 90 days. This applies to travelers holding a standard civilian passport.

Upon arrival, you will be granted entry for up to 90 days. No advance visa application, embassy appointment, or entry fee is required for a tourist visit under this threshold. If you are traveling on a diplomatic or official US passport, a visa is required — check with the Uruguayan embassy before departure in that case.

One US government source notes a declaration requirement for travelers carrying more than $10,000 USD (or its equivalent in other currencies) into Uruguay. Declare any amounts at or above this threshold upon arrival to avoid complications at customs.

Make sure your passport is valid for the duration of your stay. While Uruguay does not publish a specific "six months beyond entry" passport validity rule for US citizens, carrying a passport with ample remaining validity is always the safest approach. Entry requirements and policies can change — verify current requirements through the official US Embassy in Uruguay or the US Department of State website before you travel.
