Mosquitoes in Rwanda: Gorilla Trek Malaria Advice, Rift Valley Fever & Akagera (2026)

Trekkers report few mosquitoes in the cold, high country around Volcanoes National Park, and the CDC still recommends malaria prevention medicine for all of Rwanda, Kigali included. Yellow fever vaccine is generally not recommended for Rwanda itself, though a Uganda leg brings it into the plan, and the CDC's Rwanda page reports suspected Rift Valley fever.

Are there mosquitoes in Rwanda? Fewer than you might expect on a gorilla trip. Trekkers report few mosquitoes in the cold, high country around Volcanoes National Park, but the CDC recommends malaria prevention medicine for all of Rwanda, the Virungas and Kigali included. Akagera's savanna and the Lake Kivu shore tend to be warmer and buggier.

Disease risk ElevatedCDC recommends malaria medicine for all of Rwanda, with no exception for Kigali or the Virungas, and reports suspected Rift Valley fever.

Bite nuisance OccasionalLight around Volcanoes National Park by trekkers' accounts; Akagera has tsetse in parts of the park, and the lower, warmer areas tend to bite more.

Travel clinicCDC recommends malaria medicine for all areas of Rwanda. Yellow fever vaccine is "generally not recommended for travel to Rwanda" and not required on a direct trip from the US, but Rwanda requires it for travelers 1 year and older arriving from countries with yellow fever risk, which matters for a Uganda combination. See a travel clinic 4–6 weeks before you fly.

When to goThe long dry season, roughly June–September, and the shorter dry spell around December–February tend to be the lightest for mosquitoes and the easiest for trekking. March–May, the main rains, tends to be the worst. CDC's malaria advice applies in every month.

Malaria: no altitude exception

The CDC's wording is "CDC recommends that travelers going to Rwanda take prescription medicine to prevent malaria." Transmission occurs in all areas, mostly Plasmodium falciparum resistant to chloroquine. Forum posters often argue that altitude makes Kigali and Musanze low risk, and the CDC makes no exception for either. It lists atovaquone-proguanil, doxycycline, mefloquine and tafenoquine.

What we suggest you do with this: book a travel-medicine appointment 4–6 weeks before departure and bring the whole route: Kigali, the Virungas, Akagera, Lake Kivu and any Uganda leg. One visit can settle the malaria medicine and, for a combined trip, the yellow fever vaccine. Our malaria-zone checklist covers everything around the prescription.

Whatever the clinic decides, malaria mosquitoes bite from dusk to dawn. Repellent at sunset, long sleeves after dark and a net or a screened room overnight cover most of that exposure, even in the cool mountain lodges.

Yellow fever and the Uganda combination

For Rwanda alone, the CDC says "Vaccine is generally not recommended for travel to Rwanda," and the vaccine isn't required on a direct trip from the US. Rwanda does require proof from travelers 1 year and older arriving from countries with yellow fever risk. If your gorilla trip pairs the Virungas with Bwindi, the Uganda leg changes things. The CDC recommends the vaccine for all travelers to Uganda 9 months and older, and Uganda requires proof from arriving travelers 1 year and older. On a combined trip you'll need the certificate for Uganda anyway, so carry it across the border and give the clinic your routing. Our Uganda briefing covers that side, including CDC's Ebola notice for Uganda. Rwanda itself has no CDC Ebola notice.

Rift Valley fever and Akagera

The CDC's Rwanda page carries a banner: "Rwanda is reporting cases of suspected Rift Valley Fever (RVF)." The virus spreads mainly through contact with infected animals' blood, body fluids or organs, and through bites of infected mosquitoes. CDC's advice is to prevent mosquito bites, avoid contact with cattle and other livestock, and handle animal products safely. Rwanda's New Times reported in July 2026 that the outbreak was in Eastern Province, home to Akagera, with animal quarantines and bans on slaughter and meat sales in affected areas.

Akagera's daytime biter is the tsetse fly, found in certain parts of the park, according to African Parks, which manages it. The flies are drawn to dark colors, so light, khaki-type clothes on game drives help.

When to go

The long dry season, roughly June to September, and the shorter dry spell around December to February tend to be the lightest months for mosquitoes and the easiest for trekking. The main rains, roughly March to May, tend to be the worst, and the shorter rains around October and November tend to bring more too. The CDC's malaria advice doesn't change by month.

Where you're going

Volcanoes National Park, Musanze & Kinigi

Disease risk ElevatedBite nuisance Hardly any

Trekkers say the cold, high area has few mosquitoes, and lodges supply nets. CDC's malaria advice still applies here, with no exception for altitude.

city

Kigali

Disease risk ElevatedBite nuisance Occasional

Forum posters disagree about malaria risk in the capital, and the CDC makes no exception for it. Malaria mosquitoes bite from dusk, so the routine starts at dinner.

Akagera National Park

Disease risk ElevatedBite nuisance Noticeable

African Parks, which runs Akagera, says tsetse can be a problem in certain parts of the park, so wear light, khaki-type clothes on drives. It is in Eastern Province, where suspected Rift Valley fever was reported in July 2026.

lake

Lake Kivu: Rubavu & Karongi

Disease risk ElevatedBite nuisance Occasional

Lower and warmer than Musanze, so dusk tends to bring more mosquitoes. CDC warns about schistosomiasis in fresh water, and WHO reported cholera in the lakeside Rusizi and Rutsiro districts in August 2026.

The Rwanda kit

The spray covers the whole trip. Add treated clothes for Akagera.

Picaridin 20% travel sprays: odorless and quick to reapply at sundown, whether at a Kigali dinner or a lakeside lodge. One 3.4 oz bottle covers about a week of daily use for one person.
Permethrin 0.5% for safari clothes: treat light, khaki-type long sleeves and trousers at home 48 hours before you fly. It goes on fabric, never on skin.

What travelers report

Paraphrased from TripAdvisor posts about the Volcanoes National Park area and linked so you can read them in full. Neither carries a date, and conditions change with the season and the altitude.

Volcanoes National Park (Musanze/Kinigi)
Posters said the cold, high-altitude area has few mosquitoes, so they are not much of a concern. Another advised carrying repellent anyway, saying it is recommended at the trek briefing point and that lodges provide mosquito nets. TripAdvisor ↗
Mount Bisoke hike, Volcanoes National Park
A reviewer of the Bisoke hike said malaria tablets had been advised for the trip, although there did not seem to be any mosquitoes. TripAdvisor ↗

One more rule outlasts the trip. Any fever during or after your trip means a doctor visit, and you tell them you were in Rwanda and where else you traveled. Malaria can show up weeks later.

Traveler questions

Do I need malaria pills for gorilla trekking in Rwanda?

The CDC recommends malaria prevention medicine for all of Rwanda and makes no exception for Kigali or the high country around Volcanoes National Park. Trekkers report few mosquitoes there, and forum posters often argue that the altitude makes it low risk, but the CDC's recommendation covers the whole country. Which medicine fits you is a call for a travel clinic, made 4–6 weeks before departure. Our malaria-zone checklist covers the rest of the preparation.

Do I need a yellow fever vaccine for Rwanda?

The CDC says "Vaccine is generally not recommended for travel to Rwanda," and Rwanda doesn't require it on a direct trip from the US. It does require proof from travelers 1 year and older arriving from countries with yellow fever risk. A Uganda leg changes the picture. The CDC recommends the vaccine for all travelers to Uganda 9 months and older, and Uganda requires proof from arriving travelers 1 year and older, so carry the certificate into Rwanda and give the clinic your full routing.

What does the Rift Valley fever warning mean for visitors?

The CDC's Rwanda page says "Rwanda is reporting cases of suspected Rift Valley Fever (RVF)." The virus spreads mainly through contact with the blood, body fluids or organs of infected animals and through bites of infected mosquitoes, and it isn't known to spread from person to person. CDC's advice is to prevent mosquito bites, avoid contact with cattle and other livestock, and handle, eat and drink animal products safely. Rwanda's New Times reported in July 2026 that the outbreak was in Eastern Province, where Akagera is.

Are there tsetse flies in Akagera?

In places. African Parks, which manages the park, says tsetse can be a problem in certain parts of Akagera, calls the bite unpleasant but generally harmless and says no sleeping sickness cases are known there. The CDC's Rwanda page doesn't list sleeping sickness. The flies are drawn to dark colors, so wear light, khaki-type clothes on game drives.
