Peru Travel Health Guide: Vaccines, Risks & Safety Tips

Your Health Guide to Traveling in Peru

Peru is one of those destinations that stays with you long after you land back home. The ancient stones of Machu Picchu, the depth of the Amazon canopy, the salt flats shimmering at altitude — it is the kind of trip people talk about for years. If you are thinking seriously about travel to Peru, health preparation is one of the most important things you can do before you board that flight, and this guide walks you through everything you need to know.

Peru spans three dramatically different environments: the Pacific coast, the high Andes, and the Amazon basin. Each one carries its own health considerations, from altitude exposure in Cusco to mosquito-borne risks in the jungle lowlands. This page covers health risks, recommended vaccinations, food and water safety, common traveler illnesses, and visa requirements for US citizens — all in one place, organized so you can plan with confidence.

WayPax is here to be your travel health companion from the moment you start planning. Think of this guide as the foundation, and WayPax as the team that helps you build the rest of your plan around your specific itinerary and health history.

Frequently Asked Questions

Do I need a health form to travel to Peru?

No health form or health affidavit is currently required for US citizens entering Peru as tourists. According to the US Department of State, no vaccinations are listed as mandatory for entry. You will need a valid passport and proof of onward or return travel, but no health paperwork is required at the border.

What is the Peru travel health affidavit?

There is no standing Peru travel health affidavit requirement for US citizens under current entry rules. The US Department of State confirms that vaccinations are not a condition of entry. Requirements can change, so check official sources close to your departure date.

Do I need vaccines before traveling to Peru?

No vaccines are legally required for entry, but several are strongly recommended depending on where in Peru you are going. According to the CDC, you should be up to date on all routine vaccines before travel, and additional vaccines such as yellow fever may be recommended if your itinerary includes jungle or lowland areas. Your specific vaccine needs depend on your route and health history, so a travel health provider is the right person to finalize your plan.

Is tap water safe to drink in Peru?

Tap water in Peru is not safe to drink. Stick to bottled, boiled, or filtered water throughout your trip, including in cities like Lima and Cusco. Be cautious with ice in drinks and with raw foods that may have been washed in tap water, as these carry the same risk.

What common travel illnesses should I prepare for in Peru?

The most common illness you are likely to encounter is travelers' diarrhea (an upset stomach and loose stools caused by bacteria or parasites in contaminated food or water). According to the CDC, Peru is a moderate- to high-risk country for this. If you are heading to high-altitude destinations like Cusco or Machu Picchu, altitude sickness is another serious consideration that deserves advance planning.

Do I need travel health insurance for Peru?

Travel health insurance is not a legal requirement for entering Peru, but it is a practical one. Medical care in remote areas of Peru can be limited, and evacuation from high-altitude or jungle destinations is expensive. A policy that covers emergency medical treatment and medical evacuation gives you real protection for the kinds of environments Peru involves.

How do I find Peru travel health advice before my trip?

The CDC and the UK government travel health advisory are two of the most reliable starting points for Peru travel health advice. For personalized guidance that accounts for your specific itinerary and health history, a licensed travel health provider or travel medicine clinic is the most thorough option. WayPax connects you with the tools and guidance to build that plan before you leave.

Get Your Personalized Travel Health Plan for Peru

Peru's health profile shifts dramatically depending on whether your itinerary takes you into the Andes, the Amazon, or both. If your route includes jungle or lowland areas, a licensed travel health provider will need to assess whether malaria prevention medicine or yellow fever vaccination is right for you based on your specific plans and health history. The right preparation makes the difference between a trip you remember for the right reasons and one you spend recovering from.

Health Risks in Peru

Peru's health risks are real but manageable. What makes Peru different from many destinations is that the risks you face depend almost entirely on where in the country you are going, not just the fact that you are going to Peru.

Mosquito-Borne Diseases

Malaria (a blood infection spread by the bite of infected Anopheles mosquitoes) is a risk in certain regions of Peru, particularly in the Amazon basin and tropical lowland areas. According to the CDC, prescription malaria prevention medicine is recommended for travelers going to those areas. Whether that applies to your trip is a decision a licensed travel health provider makes based on your specific itinerary and health history — it is not a blanket recommendation for all of Peru.

Yellow fever (a serious viral illness spread by mosquito bites in tropical areas) is also a risk in specific lowland regions. A 2025 alert from the US Embassy in Lima noted a CDC Level 2 Travel Health Notice for yellow fever in specific areas of South America including Peru. Importantly, yellow fever vaccination is not generally recommended for travelers going only to Lima, Cusco, Machu Picchu, or the Inca Trail.

Zika virus (a mosquito-borne infection that can cause birth defects if contracted during pregnancy) and Oropouche virus disease (a viral illness spread by midges and mosquitoes in tropical areas) are both reported health risks in Peru, according to the UK government travel health advisory. Using insect repellent with DEET, wearing long sleeves and trousers in the evenings, and sleeping under a mosquito net in jungle areas all reduce your exposure meaningfully.

Altitude-Related Illness

Peru's Andes create some of the most dramatic altitude exposure in South American travel. Cusco sits at roughly 3,400 meters above sea level, and the surrounding region includes Machu Picchu, the Colca Canyon, and Kuélap — all destinations where altitude sickness (a condition caused by reduced oxygen at high elevation, producing headache, nausea, dizziness, and fatigue) is a genuine risk, according to the UK government travel health advisory. Ascending gradually, staying well hydrated, avoiding alcohol in the first 24 to 48 hours, and speaking with a travel health provider about acclimatization strategies before you leave are the most practical steps you can take.

Waterborne and Flood-Related Illness

The CDC has flagged major flooding in multiple districts of Peru and warns of increased waterborne disease risk as a result, including leptospirosis (a bacterial infection spread through contact with water or soil contaminated by animal urine, which can cause fever, muscle pain, and in severe cases organ damage). Avoid contact with floodwater, and treat any standing water exposure as a potential health risk. Land travel in active flood zones carries additional dangers beyond illness.

Enteric Infections

According to the CDC's Yellow Book, Peru is a moderate- to high-risk country for enteric infections (illnesses affecting the digestive system, typically caused by bacteria, viruses, or parasites in food or water). This applies across the country, not only in rural areas. Careful food and water choices are your primary defense throughout your entire trip.

Recommended Vaccinations for Peru

No vaccines are required for entry to Peru for US citizens, but several are recommended depending on your itinerary. According to the CDC, being up to date on all routine vaccines before travel is the starting point for every traveler.

• Routine vaccines (MMR, Tdap, flu, and others): These protect against diseases including measles, mumps, rubella, tetanus, and influenza. The CDC advises all international travelers to be fully vaccinated with the MMR vaccine (measles-mumps-rubella) before travel. Confirm your routine vaccines are current at least four to six weeks before departure.
• Yellow fever vaccine: This protects against a serious mosquito-borne viral illness found in tropical lowland areas of Peru. It is recommended for travelers visiting those risk areas, but according to the US Embassy in Lima, it is not generally recommended for travelers going only to Lima, Cusco, Machu Picchu, or the Inca Trail. Get this vaccine at least ten days before entering a risk area, as it takes time to become effective.
• Hepatitis A (a liver infection spread through contaminated food or water): This vaccine is widely recommended for travel to Peru given the food and water safety profile. A travel health provider can confirm whether your existing immunity is sufficient or whether a booster is needed.
• Typhoid (a bacterial illness spread through contaminated food and water that causes high fever and serious illness): Recommended for most travelers to Peru, particularly those eating outside of tourist hotels or visiting smaller towns. Get this vaccine at least two weeks before departure.

Your exact vaccine needs depend on your itinerary, your health history, and how much time you have before departure. A licensed travel health provider or travel medicine clinic is the right resource to finalize your vaccination plan for Peru.

Tap Water and Food Safety in Peru

Tap water in Peru is not safe to drink. This applies across the country, including in Lima and Cusco.

Water Safety

Stick to bottled water, boiled water, or water that has been filtered and purified throughout your trip. This guidance comes from multiple Peru-based travel health sources, including Dos Manos Peru. Tap water in Cusco is considered fine for washing hands and showering, according to Cusi Travel, but drinking it is a different matter entirely. Carry a reusable water bottle with a built-in filter as a practical backup, especially in areas where bottled water is harder to find.

Ice is a common source of contamination that travelers overlook. Unless you know a restaurant or bar is using purified water for its ice, skip it. The same logic applies to fresh juices and blended drinks made with tap water.

Food Safety

Peruvian food is genuinely excellent, and you do not need to avoid street food entirely. What matters is choosing vendors with high turnover (meaning the food is cooked fresh and hot), avoiding raw or undercooked shellfish, and being cautious with salads and raw vegetables that may have been washed in tap water. As Explorandes notes, foods washed in untreated water carry the same risk as drinking it directly. Fruit you peel yourself is generally safe. Cooked food served hot is your safest choice throughout the trip.

Common Traveler Illnesses in Peru

The illnesses that most commonly affect travelers in Peru fall into two broad categories: digestive illness from food and water exposure, and physical stress from altitude. Both are very manageable with the right preparation.

Travelers' Diarrhea

Travelers' diarrhea is an intestinal illness caused by bacteria, viruses, or parasites in contaminated food or water. Symptoms include loose stools, stomach cramps, nausea, and sometimes fever. According to the CDC, Peru is a moderate- to high-risk country for this condition. Prevention centers on careful food and water choices throughout the trip. If you develop symptoms, staying hydrated is the immediate priority. Oral rehydration salts (packets that replace the fluids and electrolytes lost through diarrhea) are widely available in Peruvian pharmacies and worth packing. Seek medical care if symptoms are severe, include blood, or last more than 48 to 72 hours.

Altitude Sickness

Altitude sickness (also called acute mountain sickness, a condition where your body struggles to adjust to lower oxygen levels at high elevation) is a serious and frequently underestimated risk in Peru's highland destinations. Symptoms include headache, nausea, dizziness, fatigue, and difficulty sleeping. The UK government travel health advisory specifically names Cusco, Machu Picchu, the Colca Canyon, and Kuélap as high-risk areas. Give yourself at least one full rest day in Cusco before attempting strenuous activity, avoid alcohol on your first night, and drink plenty of water. If symptoms worsen or you develop confusion or difficulty breathing, descend to a lower altitude and seek medical care immediately.

Leptospirosis During Flooding

Leptospirosis is a bacterial infection transmitted through contact with water or soil contaminated by animal urine, and its risk rises sharply during flooding. The CDC has flagged active flooding in multiple Peruvian districts and warns travelers to avoid floodwater entirely. Symptoms include sudden fever, headache, muscle pain, and in severe cases jaundice (yellowing of the skin and eyes) or kidney problems. If you have been in contact with floodwater and develop these symptoms, seek medical attention promptly and tell the doctor about your exposure.

Measles

Measles is a highly contagious viral illness spread through the air. The CDC advises all international travelers to confirm they are fully vaccinated with the MMR vaccine before departure. Symptoms include high fever, cough, runny nose, and a distinctive red rash. Full vaccination is the most effective prevention available.

Visa Requirements for US Citizens Visiting Peru

US citizens do not need a tourist visa to enter Peru for stays of fewer than 90 days. According to the US Department of State, entry is granted at the border without advance visa processing for tourism purposes.

You will need a passport valid for at least six months beyond your travel dates, according to the US Embassy in Lima. You must also carry proof of onward or return travel, such as a printed or digital copy of your return flight booking. Peru's immigration officers do check this at entry.

No vaccination proof is required for entry under current rules. The US Department of State country information page lists vaccinations as "None" under entry requirements. That said, entry policies can change, and you should verify current requirements with official government sources in the weeks before you travel.

Quick Answers

I am traveling to Peru soon, what health precautions should I take before departure?

Before traveling to Peru, confirm your routine vaccines are up to date and consult a travel health provider about whether yellow fever vaccination or malaria prevention medicine is appropriate for your specific itinerary, particularly if it includes jungle or lowland areas. According to the CDC, Peru is a moderate- to high-risk country for enteric infections (digestive illnesses from contaminated food or water), so planning your food and water approach before you leave is equally important. If your route includes high-altitude destinations like Cusco or Machu Picchu, ask your provider about altitude sickness prevention as well.

Can you explain whether I need a Peru travel health form or health affidavit before I travel?

No Peru travel health form or health affidavit is currently required for US citizens. According to the US Department of State, vaccinations are not a condition of entry and no health paperwork is listed as a requirement. You should carry a valid passport with at least six months of remaining validity and proof of onward travel, per the US Embassy in Lima. Always verify requirements with official sources close to your departure date, as policies can change.

What travel health insurance should I consider for Peru, and is it necessary for my trip?

Travel health insurance is not legally required for entry to Peru, but it is strongly worth having given the destination's terrain and health profile. Medical evacuation from high-altitude areas like Cusco or from remote Amazon regions is expensive, and standard US health insurance often does not cover international care. A policy that includes emergency medical treatment and medical evacuation covers the scenarios most likely to matter in Peru.

I want Peru travel health advice, including vaccines, common illnesses, and basic safety steps.

For comprehensive Peru travel health advice, start with the CDC destination page, which covers vaccines, disease risks, and current health notices including an active flooding advisory. Vaccine recommendations depend on your itinerary: yellow fever and malaria prevention are relevant for jungle and lowland travel but not for Lima or the main highland circuit. Common illnesses include travelers' diarrhea, altitude sickness in highland destinations, and mosquito-borne diseases in tropical areas. Basic safety steps include drinking only bottled or purified water, using insect repellent with DEET, and planning your altitude acclimatization before arrival.

Before I travel to Peru, can you walk me through water safety, food safety, and health risks I should know?

Tap water in Peru is not safe to drink anywhere in the country. Drink bottled, boiled, or filtered water, and avoid ice unless you know it was made with purified water, as noted by Dos Manos Peru. For food, choose freshly cooked hot dishes and peel your own fruit. On the health risk side, the CDC classifies Peru as moderate to high risk for enteric infections, the UK government travel health advisory flags altitude sickness as serious in Cusco, Machu Picchu, the Colca Canyon, and Kuélap, and the CDC warns of increased waterborne disease risk including leptospirosis due to active flooding in multiple districts.

Your Peru Trip Deserves a Complete Health Plan

Altitude sickness in Cusco, travelers' diarrhea from a single meal, a mosquito bite in the wrong lowland region — these are the things that cut trips short, and every one of them is addressable with the right preparation. A licensed travel health provider can review your full itinerary and health history to determine what food and water precautions, altitude strategies, and mosquito protection measures make sense for your specific journey through Peru.

WayPax gives you the tools to build that plan before you leave, so you arrive ready for everything Peru has to offer.
