Mosquitoes in Burundi: Very High Malaria Risk, Yellow Fever & Lake Tanganyika (2026)

WHO counted nearly 4.9 million malaria cases in Burundi in 2023, and CDC recommends malaria prevention medicine for every part of the country. Burundi also requires proof of yellow fever vaccination from arriving travelers 9 months and older, and CDC lists Zika.

Yes, and malaria is the reason to plan carefully. The CDC recommends prevention medicine for every part of Burundi, Bujumbura and the Lake Tanganyika shore included, and WHO counted about 399 malaria cases for every 1,000 people in 2023. Burundi also requires proof of yellow fever vaccination from every arriving traveler 9 months and older.

Malaria: very high, in every month

WHO reported 4,857,556 malaria cases in Burundi in 2023, 46% of them in children under five, and malaria accounted for 20.9% of medical consultations that year. The CDC's wording is "CDC recommends that travelers going to Burundi take prescription medicine to prevent malaria." Transmission occurs in all areas, mostly chloroquine-resistant Plasmodium falciparum. CDC also notes that people visiting friends and relatives are the travelers most often caught out, because they often skip prevention medicine.

What we suggest you do with this: CDC recommends malaria medicine for all areas of Burundi, and its yellow fever advice is "Vaccine is recommended for all travelers ≥9 months old." Burundi's rule is "Vaccine is required for all arriving travelers ≥9 months old," so every traveler that age, children included, needs the yellow card at the border, on a direct trip from the US too. Book a travel-medicine appointment 4–6 weeks before departure and bring your full route, including any Rwanda or Tanzania leg. Our malaria-zone checklist covers everything around the prescription.

The CDC's Burundi page names Zika and African tick-bite fever as its bug-borne diseases and lists neither dengue nor chikungunya. If you're pregnant, CDC says to "Talk to a health care provider about potential risks. If you decide to travel, prevent mosquito bites and sexual exposure to Zika."

Bujumbura and the lake

Malaria mosquitoes bite from dusk to dawn. Reviewers of Bujumbura hotels find more of them by Lake Tanganyika than downtown, and reviews of lakeshore hotels describe bed nets that don't close or are too small for the bed, so check yours before the first night and pack tape or your own net. Repellent at sunset, long sleeves after dark and a screened or air-conditioned room cover the rest. CDC warns against swimming in fresh, unchlorinated water because of schistosomiasis, and that includes the Lake Tanganyika beaches.

Two notes beyond insects. Burundi had no Ebola cases in WHO's October 23 update, though WHO rates the risk as high for countries that border the DRC, and a crossing into the DRC brings CDC's rule that anyone who has been there within 21 days can't board a commercial flight to the US. The State Department rates Burundi Level 3, Reconsider Travel, with Level 4 for Cibitoke and Bubanza provinces, Kibira National Park and the former Central Market in Bujumbura, as reported; check the current advisory.

When to go

WHO describes malaria transmission in Burundi peaking from about April to June. July to September, the dry season, tends to be the lightest for mosquitoes, and April to June the worst. CDC's advice applies in every month.

Where you're going

Bujumbura

Disease risk ElevatedBite nuisance Noticeable

CDC makes no city exception for malaria, so the evening routine starts the night you land. Downtown hotels tend to have fewer mosquitoes than the lakeshore, by reviewers' accounts.

The buggiest stretch by reviewers' accounts, with complaints about bed nets that don't close or don't fit. Enjoy the lake from the sand, since CDC warns against freshwater swimming.

The State Department advises against travel to Kibira, as reported. The cool montane forest tends to have fewer mosquitoes, and CDC's malaria advice covers it like everywhere else.

What travelers report

Paraphrased from a TripAdvisor hotel review and linked so you can read it in full. It isn't dated, and bites in Bujumbura vary with the hotel and how close it sits to the lake.

One more rule outlasts the trip. Any fever during or after your trip means a doctor visit, and you tell them you were in Burundi. Malaria can show up weeks later, and the rule holds for a year after you get home.

Traveler questions

Do I need malaria pills for Bujumbura?

The CDC recommends malaria prevention medicine for all of Burundi and makes no exception for Bujumbura or any season. WHO reported about 399 malaria cases for every 1,000 people in 2023. CDC notes that people visiting friends and relatives are at higher risk because they often skip prevention medicine, so a family stay needs the same plan as a hotel. 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 certificate for Burundi?

Yes. The CDC's recommendation is "Vaccine is recommended for all travelers ≥9 months old," and Burundi's entry requirement is "Vaccine is required for all arriving travelers ≥9 months old." That applies on a direct trip from the US, so carry the certificate with your passport for everyone in the family who is 9 months or older.

Can I swim in Lake Tanganyika?

CDC says schistosomiasis is found in Burundi and advises avoiding swimming in fresh, unchlorinated water, such as lakes, ponds or rivers, and that covers the Lake Tanganyika beaches. Enjoy the lake from the sand, and bring repellent for the evenings, when lakeshore mosquitoes are at their worst.

Is Zika a concern in Burundi if I'm pregnant?

The CDC lists Zika for Burundi and places Burundi among areas with current or past transmission but no Zika outbreak. For pregnant travelers, CDC's advice is: "Talk to a health care provider about potential risks. If you decide to travel, prevent mosquito bites and sexual exposure to Zika." Zika spreads through Aedes mosquitoes, which bite by day, so the repellent routine starts in the morning.
