Health and Vaccines in Peru:
A Practical Guide for Safe Travel

Before traveling to Peru, it is advisable to learn about recommended vaccines, health precautions to take, and potential risks related to altitude or certain regions of the country. Whether you plan to visit Lima, Cusco, Machu Picchu, Lake Titicaca, or the Peruvian Amazon, a few simple measures will help you travel with peace of mind. This practical guide presents the main recommendations concerning health, vaccines, hygiene, mosquitoes, altitude sickness, and the medical kit to prepare before your departure.

1. Vaccines for traveling to Peru

Are vaccines mandatory for traveling to Peru?

For the majority of travelers, no vaccine is mandatory to enter Peruvian territory. However, it is recommended to be up to date with routine vaccinations before departure.

⚠️ Important: Yellow fever vaccine mandatory for certain areas

The yellow fever vaccine is mandatory if you plan to visit jungle areas located below 2,300 meters (7,550 feet) in altitude, particularly in the following regions:
  • Madre de Dios (Puerto Maldonado, Tambopata Reserve)
  • Loreto (Iquitos, Pacaya Samiria National Park)
  • Ucayali (Pucallpa)

📌 Important to know: The vaccine must be administered at least 10 days before arriving in a risk area. An International Certificate of Vaccination (Yellow Card) will be required upon entry to these regions.

If your trip is limited to Lima, Cusco, Arequipa, Machu Picchu, or Lake Titicaca, this vaccination is generally not required.

Generally recommended vaccines

As with many destinations, it is recommended to be up to date with common vaccines: tetanus, diphtheria, polio, whooping cough. Depending on your itinerary, other vaccines (hepatitis A, typhoid, rabies) may also be advised by a healthcare professional.

💡 Good to know

Vaccination needs vary depending on whether you plan an urban stay, a circuit in the Andes, a high-altitude trek, or a trip to the Amazon. Personalized medical advice remains the best solution before departure.

2. Altitude sickness, soroche and high altitude in Peru

What is altitude sickness?

Acute mountain sickness, locally called soroche, can occur when ascending rapidly to high altitude without sufficient acclimatization. In Peru, many very popular destinations such as Cusco, Lake Titicaca, the Puno region, the Cordillera Blanca, and other Andean sites far exceed 3,000 meters (9,800 feet) above sea level.

The most common symptoms are headaches, fatigue, nausea, dizziness, shortness of breath, and sometimes sleep disturbances. In most cases, these symptoms remain mild and disappear after a few hours or days of adaptation.

How to limit the effects of altitude?

Proper acclimatization is the best prevention. When possible, plan a gradual arrival in high-altitude regions and avoid strenuous physical activity during the first 24 to 48 hours.

It is also recommended to stay well hydrated, eat lightly, and avoid excessive alcohol consumption during the first few days. Everyone reacts differently to altitude: age and physical condition do not guarantee better adaptation.

💡 Good to know

Many travelers choose to spend one or two quiet days in Cusco before embarking on more demanding treks or excursions. This adaptation period often helps reduce altitude-related effects.

Is coca tea effective?

In the Peruvian Andes, coca tea (mate de coca) is traditionally consumed to help cope with altitude. Many hotels offer this drink to their visitors upon arrival.

Even though many travelers report a feeling of relief, coca tea does not replace proper acclimatization or the advice of a healthcare professional. It should be considered as a complementary aid, not a miracle cure.

When to see a doctor?

If symptoms become severe, worsen despite rest, or are accompanied by breathing difficulties, it is recommended to consult a healthcare professional promptly. In some cases, descending to a lower altitude may be necessary.

⚠️ Important

People with heart or respiratory conditions or certain chronic illnesses should seek medical advice before traveling to high-altitude areas in Peru.

3. Mosquitoes, dengue and health risks in the Peruvian Amazon

Do mosquitoes pose a risk in Peru?

The presence of mosquitoes varies greatly depending on the region of Peru. In large coastal cities like Lima, they are generally not a problem. However, in the tropical and humid areas of the Peruvian Amazon, mosquitoes are much more numerous, especially during hot and humid periods.

Travelers planning to visit destinations such as Iquitos, Puerto Maldonado, or certain Amazon reserves should plan adequate protection against bites.

Understanding dengue: symptoms and transmission

Dengue is a viral disease transmitted by the bite of certain mosquitoes, primarily Aedes aegypti and Aedes albopictus (tiger mosquito). There is no direct human-to-human transmission. The risk mainly concerns low-altitude regions and the Amazon areas of Peru.

🦟 Dengue symptoms: what to look out for?

In most cases, dengue is asymptomatic or mild. However, it can also cause a sudden flu-like syndrome, typically appearing 4 to 10 days after the bite:
  • A high fever (up to 104°F / 40°C)
  • Severe headaches
  • Muscle and joint pain (known as "breakbone fever")
  • Nausea, vomiting or skin rashes

⚠️ Severe cases: In rare cases, dengue can progress to a severe form (hemorrhagic dengue) which can be life-threatening and requires immediate medical emergency. If you experience bleeding, intense abdominal pain, or repeated vomiting, seek medical attention immediately.

Treatment: what to do if you have dengue?

There is currently no specific antiviral medication to cure dengue. Management focuses on rest and symptom relief:

  • Rest and drink plenty of fluids
  • Paracetamol (acetaminophen) to reduce fever and relieve pain
🚫 Warning: medications to avoid!

Aspirin and non-steroidal anti-inflammatory drugs (NSAIDs) (ibuprofen, Advil, Nurofen, etc.) are strictly prohibited if dengue is suspected, as they increase the risk of bleeding and can worsen the disease.

How to protect yourself effectively?

The best protection against dengue is preventing mosquito bites. Here are the essential steps to take, especially in the Amazon:

  • Wear light-colored but covering clothing (long pants, long sleeves), especially at sunrise and sunset.
  • Use an appropriate insect repellent (containing DEET, icaridin, or PMD).
  • Sleep under an insecticide-treated mosquito net if your accommodation is not air-conditioned or equipped with window screens.
  • Eliminate standing water around your lodging (where mosquitoes breed).
💡 Good to know

Even if you are only planning a short excursion to the Amazon, pack mosquito repellent in your luggage. Light and compact, it can prove very useful during your trip. Mosquitoes are active all day, but exposure is higher in the morning and late afternoon.

Should you worry when traveling to Lima, Cusco, or Machu Picchu?

For most travelers who limit themselves to Lima, Cusco, the Sacred Valley, Machu Picchu, Arequipa, or Lake Titicaca, mosquitoes are generally not a major concern. These regions are at high altitude or in arid areas where mosquitoes are rare.

The main health precautions in these areas relate more to altitude, sun exposure, or temperature variations.

⚠️ Important

Health conditions and recommendations may change. Before your departure, consult the official information from your country as well as updated recommendations regarding the regions you plan to visit.

4. Drinking water, food and hygiene in Peru

Can you drink tap water in Peru?

As a precaution, it is generally recommended that travelers do not drink tap water in Peru. Most locals use filtered, boiled, or bottled water for their daily consumption.

To avoid digestive issues during your stay, choose sealed bottled water or suitable filtration solutions when traveling in more remote areas.

How to avoid digestive problems?

As with many destinations, changes in diet, water, or lifestyle can cause some digestive issues for certain travelers. Fortunately, these inconveniences are generally mild and temporary.

It is advisable to choose busy establishments, check the freshness of food, and wash your hands regularly before meals.

💡 Good to know

Peruvian cuisine is renowned worldwide. Don't hesitate to discover local specialties, while using common sense regarding food hygiene and storage.

Are markets and street food safe?

Local markets and street food are an integral part of the travel experience in Peru. Many travelers eat there daily without encountering any particular problems.

Simply follow a few basic precautions: choose busy stalls, food prepared in front of you, and properly stored products.

Watch out for sun exposure and dehydration

At high altitude, solar radiation can be particularly intense, even when temperatures feel pleasant. In Cusco, at Lake Titicaca, or during treks in the Andes, good sun protection is strongly recommended.

Also remember to drink regularly to limit the risk of dehydration, especially during physical activities or excursions at high altitude.

⚠️ Caution

Sunburn can occur quickly at high altitude, even on cloudy days. A hat, sunglasses, and appropriate sunscreen are useful items to have when traveling in Peru.

5. Medical kit and travel insurance for Peru

Why prepare a travel medical kit?

Even though pharmacies are numerous in Peru's major cities, it is always useful to travel with a small medical kit. It allows you to quickly deal with everyday minor issues without having to search for a pharmacy in an emergency.

This precaution is particularly useful during excursions in the Andes, stays in the Amazon, or in more remote regions where medical services may be less accessible.

What to put in your medical kit?

The contents of your kit depend on your health condition, the length of your stay, and the regions you plan to visit. A basic kit may include a few commonly used items by travelers.

💡 Items often carried by travelers

• Personal medications prescribed by your doctor
• Bandages and antiseptic
• Thermometer
• Insect repellent
• Sunscreen and lip balm
• Hand sanitizer
• Basic first aid supplies adapted to your needs

If you are on regular medication, pack enough for the entire trip as well as a prescription if necessary.

Are pharmacies easy to find?

In major cities like Lima, Cusco, Arequipa, or Trujillo, pharmacies are numerous and generally easy to find. Some are open late in the evening and offer a wide range of common health products.

In rural areas or remote regions, the availability may be more limited. It is therefore preferable to plan ahead for what you might need during your stay.

Is travel insurance necessary?

Travel insurance is generally not mandatory to enter Peru, but it is strongly recommended. It can cover medical expenses, assistance, repatriation, or certain travel-related unforeseen events.

Before your departure, take the time to check the coverage included with your credit card or insurance contract to know exactly your level of protection.

⚠️ Important

Make sure your insurance covers the activities planned during your stay, particularly high-altitude treks or certain adventure activities that may be subject to specific conditions.
