Frequently Asked Questions

What health advice should I check before traveling to Peru?

Before traveling to Peru, review your vaccination status, understand the mosquito-borne and waterborne disease risks specific to the regions you plan to visit, and pack a travel health kit that includes insect repellent and water purification options. Peru's health profile varies significantly by altitude and geography — the Amazon lowlands carry different risks than the Andean highlands. Visiting a travel health clinic at least four to six weeks before departure gives you time to complete any recommended vaccine courses. According to the CDC, your itinerary within Peru is one of the most important factors in determining which precautions apply to you.

Do I need vaccines before traveling to Peru?

Yes, several vaccines are recommended before traveling to Peru. According to the CDC, all travelers should be up to date on routine vaccines and should ensure they are fully vaccinated against measles with the MMR (measles-mumps-rubella) vaccine. Hepatitis A and Hepatitis B vaccines are also recommended for most travelers. Yellow fever vaccination is advised depending on which regions of Peru you plan to visit, so your specific itinerary matters when making vaccine decisions.

Is tap water safe to drink in Peru?

No, tap water in Peru is not safe to drink. The WHO recommends avoiding tap water throughout the country, including in Lima and other major cities. Stick to sealed bottled water, water that has been boiled, or water treated with a certified filter or purification tablets. This applies to ice in drinks as well — if you are unsure of the water source, skip the ice.

What common illnesses do travelers get in Peru?

Travelers' diarrhea is the most frequently reported illness among visitors to Peru, and according to the CDC, Peru is classified as a moderate- to high-risk destination for enteric infections (illnesses caused by consuming contaminated food or water). Mosquito- and midge-borne illnesses such as malaria, chikungunya, and Oropouche are also reported in certain regions. Altitude sickness (a condition caused by reduced oxygen at high elevations) is a significant non-infectious risk for anyone visiting high-altitude destinations like Cusco or Lake Titicaca.

Do I need travel health insurance for Peru?

Travel health insurance for Peru is strongly advisable, even though it is not a formal entry requirement. Medical evacuation from remote areas — including high-altitude Andean locations or jungle regions — can be extremely costly without coverage. Look for a policy that includes emergency medical evacuation, hospitalization, and coverage for adventure activities if your itinerary includes trekking or outdoor pursuits. Confirm your policy covers pre-existing conditions and the specific regions of Peru you plan to visit.

Is there a health form required to travel to Peru?

As of current available guidance, there is no mandatory health form required for entry into Peru for US citizens traveling for tourism. Entry requirements focus on passport validity and proof of onward travel rather than health documentation. That said, requirements can change — especially in response to disease outbreaks — so check the US Embassy in Peru's website and the CDC's travel notices for Peru in the weeks before your departure to confirm the latest entry conditions.

What health risks should I know before visiting Peru?

Peru's health risks vary by region and include mosquito-borne diseases in the Amazon lowlands, altitude sickness in the Andes, and food- and waterborne illnesses across the country. According to the CDC, current elevated concerns include flooding-related leptospirosis (a bacterial infection spread through contact with contaminated floodwater) and Oropouche virus (a viral illness spread by infected midges and mosquitoes). Yellow fever and malaria risks are present in specific areas rather than throughout the entire country. With the right vaccinations, insect precautions, and safe food and water habits, most of these risks are very manageable.

Get Your Personalized Travel Health Plan for Peru

Peru's geography creates a uniquely layered health profile — mosquito-borne diseases in the Amazon, altitude sickness in the Andes, and active flooding in some districts that elevates the risk of leptospirosis (a bacterial infection spread through floodwater). A one-size-fits-all approach does not work here. Your Trip Kit is built around your exact itinerary, your health history, and the regions of Peru you are actually visiting — so you get the guidance that is relevant to your trip, not a generic checklist.

Health Risks in Peru

Peru presents a medium-level travel health profile with risks that are strongly tied to where in the country you are going. Understanding these risks by category gives you a clear picture of what to prepare for — and what to do about each one.

Mosquito- and Midge-Borne Diseases

Peru's Amazon basin and lowland jungle regions carry a meaningful risk of mosquito- and midge-borne illness. According to the CDC, malaria (a serious blood infection caused by a parasite transmitted through mosquito bites) is present in certain areas of Peru, and prescription prevention medication is recommended for travelers heading to those zones. The CDC also lists chikungunya (a viral illness causing fever and severe joint pain) and Zika virus (a viral infection that poses particular risks during pregnancy) as active concerns. Oropouche virus — a viral illness spread primarily through the bites of infected midges (tiny biting insects also called no-see-ums) and some mosquitoes — is a current CDC travel health notice for Peru. Use an EPA-registered insect repellent containing DEET or picaridin, wear long sleeves and trousers during dawn and dusk hours, and sleep under a permethrin-treated bed net where mosquitoes are prevalent.

Yellow Fever

According to the CDC and the WHO, yellow fever (a potentially severe viral illness spread by mosquito bites) is a risk in specific regions of Peru, particularly in jungle and lowland areas. It is not a risk in Lima or at high altitudes. The CDC recommends yellow fever vaccination for travelers visiting at-risk areas. If you are arriving from a country where yellow fever is endemic (naturally occurring), some entry points may require proof of vaccination. Check whether your specific itinerary puts you in a yellow fever risk zone before you travel.

Waterborne Diseases and Flooding Risk

According to the CDC and the WHO, Peru is currently experiencing significant flooding in multiple districts, which raises the risk of waterborne disease exposure beyond the usual baseline. Leptospirosis (a bacterial infection that enters the body through skin contact with water or soil contaminated by animal urine) is a specific concern during flood conditions. Avoid wading through or touching floodwater, follow instructions from local authorities in affected areas, and be aware that land travel in flood zones may be unsafe. Even outside flooded areas, waterborne illness is a consistent risk throughout Peru.

Altitude Sickness

If your itinerary includes high-altitude destinations such as Cusco, Machu Picchu, or Lake Titicaca, altitude sickness (also called acute mountain sickness, or AMS — a condition caused by lower oxygen levels at high elevation) is a real concern. The WHO notes altitude sickness as a significant risk in high-altitude parts of Peru. Symptoms include headache, nausea, dizziness, and fatigue. Ascend gradually where possible, allow yourself one to two days to acclimatize before strenuous activity, stay well hydrated, and speak with a travel health provider before departure about whether preventive medication such as acetazolamide (a prescription drug that can reduce altitude sickness symptoms) is appropriate for you.

Enteric Infections and Food-Related Illness

According to the CDC, Peru is a moderate- to high-risk destination for enteric infections (illnesses caused by consuming food or water contaminated with bacteria, viruses, or parasites). This category includes a range of gastrointestinal illnesses beyond travelers' diarrhea. Practice strict food hygiene: eat only thoroughly cooked food, choose restaurants with high turnover and visible hygiene standards, and avoid raw salads washed in tap water, unpasteurized dairy products, and food from street stalls that does not appear freshly prepared and hot.

Recommended Vaccinations for Peru

Several vaccinations are recommended before traveling to Peru, and the right ones for you depend on your health history and the specific regions you plan to visit. According to the CDC, the following vaccines deserve your attention before departure.

• Hepatitis A — protects against hepatitis A (a liver infection spread through contaminated food or water). According to the CDC, this vaccine is recommended for all unvaccinated travelers age one year and older going to Peru; infants aged six to eleven months should also be vaccinated before travel. Get the first dose at least two weeks before departure, ideally earlier.
• Hepatitis B — protects against hepatitis B (a liver infection spread through blood, sexual contact, and some medical procedures). According to the CDC, this vaccine is recommended for unvaccinated travelers younger than sixty; those aged sixty and older may also choose to be vaccinated. A full course typically requires three doses over several weeks, so start early.
• MMR (Measles-Mumps-Rubella) — protects against measles, mumps, and rubella (three highly contagious viral infections). According to the CDC, all international travelers should be fully vaccinated against measles. Confirm you have had two doses of MMR before traveling.
• Yellow Fever — protects against yellow fever (a potentially life-threatening viral illness transmitted by mosquitoes). According to the CDC and the WHO, this vaccine is recommended based on your travel area within Peru. If you are visiting jungle or lowland regions, discuss this vaccine with your provider at least ten days before travel, as it requires a waiting period to become effective.
• Routine Vaccines — includes diphtheria-tetanus-pertussis (protection against three bacterial infections: diphtheria, tetanus, and whooping cough), polio, influenza, varicella (chickenpox), and shingles as appropriate. According to the CDC, being up to date on all routine vaccines is a baseline requirement for any international travel.
• COVID-19 — according to the CDC, all eligible travelers should be up to date with COVID-19 vaccination before international travel.
• Chikungunya — protects against chikungunya (a viral illness causing fever and debilitating joint pain). According to the CDC, this vaccine may be considered for travelers planning an extended stay of six months or more in Peru due to elevated risk.
• Rabies — protects against rabies (a fatal viral infection transmitted through the bite or scratch of an infected animal). The WHO notes this vaccine as relevant for selected higher-risk travelers, such as those working with animals, spending extended time in rural areas, or engaging in outdoor activities where animal contact is possible.

Your specific vaccine needs depend on your health history, age, previous vaccinations, and the regions of Peru you plan to visit. A travel health provider or clinic can review your full profile and give you a personalized recommendation — aim to have that conversation at least four to six weeks before your departure date.

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 all major tourist destinations.

Water Safety

The WHO recommends that travelers in Peru avoid drinking tap water entirely. Your safest options are sealed commercially bottled water, water that has been brought to a rolling boil for at least one minute, or water treated with a certified portable filter or purification tablets. When you brush your teeth, use bottled or treated water rather than water from the tap. Be cautious with ice in drinks — if you cannot confirm it was made from purified water, it is safer to skip it. Many hotels and restaurants in tourist areas use purified water for ice and cooking, but it is always reasonable to ask. Carry a reusable water bottle with a built-in filter as a practical backup throughout your trip.

Food Safety

Peruvian cuisine is exceptional, and you can enjoy it safely with a few clear rules. Eat food that is freshly cooked and served hot — heat kills most pathogens (disease-causing microorganisms). Ceviche and other raw or marinated seafood dishes are a Peruvian staple; choose them at reputable, busy restaurants rather than from unfamiliar vendors, and be aware that marinating in citrus juice does not fully eliminate all foodborne pathogens. Avoid raw salads and fresh vegetables that may have been washed in tap water unless you are confident in the establishment's food handling practices. Peel your own fruit where possible. Unpasteurized dairy products (milk, cheese, or yogurt that has not been heat-treated to kill bacteria) carry additional risk and are best avoided. Street food can be excellent and safe — look for stalls with high turnover, food that is cooked to order in front of you, and vendors who handle money and food separately.

Common Traveler Illnesses in Peru

The illnesses that most commonly affect travelers in Peru range from uncomfortable to serious, but nearly all of them are preventable or treatable when you know what to look for.

Travelers' Diarrhea

Travelers' diarrhea (loose or watery stools caused by consuming food or water contaminated with bacteria, viruses, or parasites) is the single most common illness reported by visitors to Peru. Symptoms typically include sudden onset of frequent, loose bowel movements, sometimes accompanied by stomach cramps, nausea, or a low-grade fever. Stay well hydrated using safe water and oral rehydration salts (electrolyte packets that replace fluids and minerals lost through diarrhea) if symptoms develop. Most cases resolve within a few days. If diarrhea is severe, bloody, or accompanied by a high fever, seek medical attention promptly rather than waiting it out.

Altitude Sickness (Acute Mountain Sickness)

Acute mountain sickness affects many first-time visitors to high-altitude areas of Peru, including Cusco, which sits at approximately 3,400 meters (11,150 feet) above sea level. It is caused by your body adjusting to thinner air with less available oxygen. Symptoms typically appear within hours of arriving at altitude and include headache, fatigue, loss of appetite, and difficulty sleeping. Rest on your first day at altitude, avoid alcohol, and drink plenty of safe water. If symptoms worsen or you develop confusion, severe shortness of breath at rest, or loss of coordination, descend to a lower altitude immediately and seek medical care — these can be signs of a more serious condition.

Leptospirosis

Leptospirosis (a bacterial infection spread when water or soil contaminated by the urine of infected animals — such as rodents or livestock — comes into contact with broken skin, eyes, or mucous membranes) is an elevated concern in Peru right now due to current flooding. Early symptoms mimic a flu-like illness: fever, headache, muscle aches, and chills. If you develop these symptoms after any contact with floodwater or natural water sources in Peru, tell a doctor immediately and mention your travel history. Early antibiotic treatment is effective, so prompt diagnosis matters.

Oropouche Virus Disease

Oropouche virus disease (a viral illness that causes fever, headache, muscle and joint pain, and sometimes a rash, spread through the bites of infected midges and some mosquitoes) is a current CDC travel health notice for Peru. There is no vaccine available for Oropouche, so prevention relies entirely on avoiding bites. Use insect repellent at all times outdoors, wear protective clothing, and use window screens or bed nets in areas where midges are active. If you develop a sudden fever and flu-like symptoms during or after your trip, mention your travel to Peru to a healthcare provider.

Visa Requirements for US Citizens Visiting Peru

US citizens do not need a visa to visit Peru for tourism — entry is granted on arrival.

When you arrive in Peru, you will receive an entry stamp in your passport. You may be asked to show proof of return or onward travel (such as a flight booking), so have that documentation accessible. Your passport must be valid for at least six months from the date of entry, and you will need at least one blank page available for the entry stamp. Make sure your passport meets both requirements before you leave home — airlines may not allow you to board if your passport is close to expiry.

Travel health insurance for Peru is not a formal entry requirement, but it is strongly recommended given the country's medical infrastructure in remote areas and the potential cost of emergency evacuation from high-altitude or jungle regions. Review your policy carefully before departure.

Entry requirements can change — sometimes quickly, particularly in response to health events or political developments. Verify the latest requirements directly with the US Embassy in Peru and the official Peruvian immigration authority before your travel date. What applies today may be different in three months.

Quick Answers

I'm traveling to Peru soon—what health precautions should I take before I go?

Before traveling to Peru, visit a travel health clinic at least four to six weeks before departure to review your vaccination status and get any recommended vaccines. According to the CDC, key precautions include ensuring you are up to date on routine vaccines and MMR, considering destination-specific vaccines such as Hepatitis A, Hepatitis B, and yellow fever based on your itinerary, and packing insect repellent and safe water supplies. If your trip includes high-altitude destinations, ask your provider about altitude sickness prevention. The CDC also advises awareness of current flooding conditions in parts of Peru, which increase the risk of waterborne illness including leptospirosis.

Can you explain what travel health advice I should follow for Peru, including vaccines and illness risks?

Peru travel health advice covers several categories: vaccinations, insect bite prevention, food and water safety, and altitude precautions. According to the CDC, recommended vaccines for most travelers include Hepatitis A, Hepatitis B, MMR, and routine vaccines; yellow fever vaccination is recommended depending on which regions you visit. The WHO highlights altitude sickness as a significant risk in high-altitude areas and advises against drinking tap water anywhere in Peru. Mosquito-borne diseases including malaria, chikungunya, and Oropouche virus are risks in lowland and jungle regions, while travelers' diarrhea is a widespread concern across the country.

Do I need travel health insurance for Peru, and what should I look for in a policy?

Travel health insurance for Peru is not a legal entry requirement, but it is strongly advisable for all travelers. Medical costs in Peru — particularly emergency evacuation from remote Andean or Amazon regions — can be extremely high without coverage. Look for a policy that includes emergency medical evacuation, inpatient and outpatient hospital coverage, and coverage for adventure or trekking activities if your itinerary includes them. Confirm that the policy covers the full duration of your trip and all regions of Peru you plan to visit, including any areas flagged for elevated health risks.

Is it safe to drink water in Peru, and how can I avoid getting sick from food or water?

No, tap water in Peru is not safe to drink. The WHO recommends drinking only sealed bottled water, boiled water, or water treated with a certified purification method throughout your time in Peru, including in Lima. To avoid food-related illness, eat food that is freshly cooked and served hot, choose busy restaurants with visible hygiene standards, avoid raw salads that may have been washed in tap water, and peel your own fruit. Avoid ice unless you can confirm it was made from purified water, and skip unpasteurized dairy products.

Are there any health forms or travel health entry requirements I need before going to Peru?

Based on current available information, US citizens traveling to Peru for tourism are not required to complete a health form or present vaccination certificates as a condition of entry. Entry requirements focus on passport validity (at least six months remaining) and proof of onward or return travel. However, entry requirements can change in response to disease outbreaks or other events, so confirm the latest requirements with the US Embassy in Peru and the CDC's Peru travel page before your departure date. Keeping a copy of your vaccination records with your travel documents is always a good practice.

I'm planning a trip to Peru—what are the main health risks and common traveler illnesses I should prepare for?

Peru's main health risks vary by region. According to the CDC, mosquito-borne diseases including malaria, chikungunya, Zika, and Oropouche virus are present in lowland and Amazon areas, while yellow fever risk exists in specific jungle regions. The WHO identifies altitude sickness as a serious risk for travelers visiting high-altitude destinations such as Cusco or Lake Titicaca. Travelers' diarrhea and other enteric infections (illnesses from contaminated food or water) are widespread concerns across the country, and the CDC notes that current flooding in parts of Peru raises the additional risk of leptospirosis. Most of these risks are manageable with the right vaccines, insect precautions, and safe food and water habits.
