The CDC recommends malaria medicine for Iquitos and Puerto Maldonado and yellow fever vaccine for the Amazon regions. Loreto has almost all of Peru's malaria, and Madre de Dios, home of the Tambopata lodges, has the country's highest dengue rate this year.

Yes, and this is the part of a Peru trip where they matter. The CDC recommends malaria medicine for Iquitos, Puerto Maldonado and everywhere below 8,200 ft (2,500 m) east of the Andes, and yellow fever vaccine for the Amazon regions. Lodge rooms are usually screened and netted, so most bites happen on trails, boats and night walks.

Malaria and yellow fever

What CDC says: malaria transmission occurs in "All areas of the country <2,500 m (<8,200 ft) elevation east of the Andes, including the cities of Iquitos and Puerto Maldonado," and for those areas it lists "Atovaquone-proguanil, doxycycline, mefloquine, tafenoquine." Yellow fever vaccine "is recommended for all travelers ≥9 months old going to areas <2,300 m (7,550 ft) elevation in the regions of" Loreto, Madre de Dios, Cusco and seven others. Under entry requirements: "Vaccine is not required." What we suggest you do with this: book a travel-medicine appointment 4–6 weeks before departure with the full itinerary. Our malaria-zone checklist covers the rest.

Malaria in Peru means Loreto, the Iquitos region. Through late September 2026, Peru's national epidemiology center counted 17,646 cases nationwide, down from 26,708 in the same weeks of 2025, and 17,383 of them were in Loreto. Most were in remote northern river districts, but Alto Nanay, near Iquitos, had 450, and San Juan Bautista, one of the city's four districts, 367.

Yellow fever is present too. PAHO counted 3 confirmed cases in Loreto in 2025, one of them fatal, and a death in Madre de Dios, then 2 confirmed cases in Madre de Dios in the first seven weeks of 2026.

Dengue moved to Madre de Dios

Through epidemiological week 38, which ended September 26, Peru's national epidemiology center counted more than ten times as many cases in Madre de Dios as in the same weeks of 2025, and the region had the country's highest rate, above 1,200 per 100,000 people. Tambopata district, home to Puerto Maldonado, had about 1,750. Loreto went the other way, with about 3,000 cases against 5,584 a year earlier, and the four Iquitos districts had 663, down from 2,458.

The dengue mosquito bites in daylight, so in Puerto Maldonado and Iquitos repellent goes on in the morning as well as at dusk.

Dusk to dawn at the lodge

Malaria mosquitoes bite from dusk to dawn, and so do the sand flies that spread leishmaniasis on forest trails. Madre de Dios reported Peru's most leishmaniasis cases in 2026, 511 through late September, 153 of them in Tambopata district. Oropouche, a virus spread mainly by a tiny biting midge, was most common in Loreto in 2025, with 164 of Peru's 330 confirmed cases through mid-July, according to PAHO. Pregnant travelers should discuss Zika and Oropouche with a healthcare provider.

Sleep under the lodge's bed net, check it for holes, tuck it in and keep the screens shut. Night walks have a reputation for heavy mosquitoes, since headlamps draw them in, so wear a thick permethrin-treated shirt and cover your ankles.

When to go

The CDC's advice doesn't change by month. In Madre de Dios the drier months, roughly May to October, are the main lodge season. Around Iquitos, high water runs about December to May and low water June to November. Dengue normally peaks in the first half of the year, though in 2026 it kept climbing into September, a rise PAHO ties to El Niño.

The Amazon lodge kit

Treated clothes do most of the work.
  • Permethrin 0.5% for jungle clothes: treat a long-sleeved shirt, trousers and socks at home 48 hours before you fly. It goes on clothing, never on skin.
  • Picaridin 20% travel sprays for daytime dengue protection and fresh coats at dusk.
  • A full-size backup in the checked bag for reapplying at dawn, at dusk and after downpours.

What travelers report

Paraphrased from TripAdvisor reviews and threads and linked so you can read them in full. None gives a year, and what you meet depends on the lodge, the season and the luck of the week.

  • Chuncho Lodge, Tambopata

    A guest had almost no mosquitoes during the stay, but noted that the guide put this down to luck and nature rather than the norm. TripAdvisor ↗

  • Tambopata Ecolodge

    A guest who liked the lodge said the rainforest was very hot and humid, with a lot of mosquitoes and other biting flies. TripAdvisor ↗

  • Tambopata (Madre de Dios)

    In an older thread, a poster disputed a lodge's claim that the area had been malaria-free for 20 years, citing a Ministry of Health bulletin that listed malaria cases in Tambopata. TripAdvisor ↗

One rule outlasts the trip. The CDC says to seek medical care right away for a fever during the trip or for up to a year after a stay in a malaria area. Tell the doctor you were in the Peruvian Amazon.

Traveler questions

Do I need malaria pills for Iquitos or Puerto Maldonado?

The CDC recommends malaria prevention medicine for all areas below 8,200 ft (2,500 m) east of the Andes, including the cities of Iquitos and Puerto Maldonado, and lists atovaquone-proguanil, doxycycline, mefloquine and tafenoquine. Which medicine suits you is a decision for a travel clinic 4–6 weeks before departure. Bring the whole route, since Cusco and Machu Picchu are outside the malaria area.

Do I need a yellow fever vaccine for the Peruvian Amazon?

The CDC recommends it for all travelers 9 months and older going to areas below 7,550 ft (2,300 m) in Loreto, Madre de Dios, Cusco and seven other regions, which covers Iquitos, Tambopata and Manu. Peru does not require it for entry. PAHO confirmed 2 cases in Madre de Dios in the first weeks of 2026, after 3 in Loreto and a fatal case in Madre de Dios in 2025. Raise it at your travel-clinic visit.

Is Tambopata or Iquitos riskier?

The risks differ. Loreto, the Iquitos region, has almost all of Peru's malaria, though most of it is in remote river districts far from the city, and its dengue fell by almost half in 2026. Madre de Dios, the Tambopata region, has the country's highest dengue rate this year and its most leishmaniasis. The CDC's malaria and yellow fever advice covers both.

Do Amazon lodges have mosquito nets?

Lodges around Iquitos tend to offer screened rooms and a net over the bed, and the CDC's Peru page advises sleeping in a screened room, under a bed net or in a screened tent. Check the net for holes, tuck it in and keep screens closed. Night walks are another matter, so wear a thick long-sleeved shirt and fresh repellent.
