Ouidah's Vodun Days fall in the dry season. Malaria advice still covers all of Benin.
- Travel clinic CDC recommends medicine or vaccines for some areas · which ones
- No CDC travel notice for mosquito-borne disease
January's festival in Ouidah falls in the dry season, which tends to be Benin's least buggy stretch, but the CDC recommends malaria prevention medicine for every part of the country in every month. Benin also checks for proof of yellow fever vaccination from every arriving traveler 9 months and older.
Are there mosquitoes in Benin? Yes, all year, and the CDC recommends malaria prevention medicine for the whole country, Cotonou, Porto-Novo, Ouidah and Ganvié included. Benin also requires proof of yellow fever vaccination from every arriving traveler 9 months and older, even on a trip straight from the US. Whether you're visiting family, on an aid or mission posting, or flying in for Ouidah's Vodun Days in January, the same clinic visit covers it.
Malaria and yellow fever: the clinic visit
The CDC's wording is "CDC recommends that travelers going to Benin take prescription medicine to prevent malaria." Transmission occurs in all areas, mostly Plasmodium falciparum resistant to chloroquine, with no exception for cities, beaches or the dry season. The CDC notes that people visiting friends and relatives are at higher risk because they often skip prevention medicine, so a family home needs the same plan as a hotel. Malaria mosquitoes bite from dusk to dawn, so put repellent on at sunset, wear long sleeves after dark and sleep in a screened or air-conditioned room or under a net.
Benin's yellow fever rule covers a direct flight from the US, so carry the yellow International Certificate of Vaccination with your passport. No confirmed cases were reported to WHO for 2025, but WHO lists Benin among 14 countries at heightened risk of a resurgence, with routine infant coverage at 49% that year.
What we suggest you do with this: the CDC recommends malaria medicine for all areas of Benin, and for yellow fever, "Vaccine is recommended for all travelers ≥9 months old." Benin's entry rule is "Vaccine is required for all arriving travelers ≥9 months old." Book a travel-medicine appointment 4–6 weeks before departure, even for a regular family visit, and bring your full route. Ask about meningococcal vaccine, which CDC recommends for meningitis-belt areas of Benin in the dry season, roughly December to June. CDC's Global Polio Level 2 notice lists Benin, so ask too about the single lifetime polio booster for adults who had the childhood series. Our malaria-zone checklist covers the rest.
Dengue by day, lagoons at dusk
The CDC lists dengue for Benin. WHO counted it among 15 African countries with dengue outbreaks in 2023 and reported ongoing transmission into late April 2024. There are no 2025 or 2026 dengue figures. Dengue's Aedes mosquitoes bite in daylight, so repellent goes on in the morning too, and our dengue & Zika routine has the schedule. At dusk, the lagoon shores around Cotonou and Ouidah and the stilt village of Ganvié tend to bring the most mosquitoes, and Pendjari's bush camps tend to be buggiest in the rains.
When to go: the Vodun Days fall in the dry season
The dry season, roughly December to March, tends to be the lightest for mosquitoes. Ouidah's Vodun Days fall inside it, held January 8–10 in 2026 around the national Vodun holiday on January 10, and so does the usual Pendjari game-viewing season. The south's rains run roughly April to July, worst from May to July, and the north has one rainy season, roughly May or June to October. The malaria advice holds in every month.
Where you're going
The State Department advises against travel to Benin's areas bordering Burkina Faso and Niger, including the Pendjari border area, and those bordering Nigeria's Kebbi, Niger and Kwara states, as reported; check the current advisory.
Cotonou
Inside CDC's malaria advice with no city exception, in a hotel or a family home. Lagoon-side areas tend to bring the most mosquitoes at dusk, so close windows and screens before sunset.
Ouidah
About 26 miles (42 km) west of Cotonou and home of the January Vodun Days. The festival falls in the dry season, but CDC's malaria advice applies in January too, so keep the sunset routine.
Ganvié & Lake Nokoué
A stilt village on Lake Nokoué, usually reached by boat from Cotonou or Abomey-Calavi. Expect mosquitoes on the water toward dusk, and don't wade in, since CDC says schistosomiasis is found in Benin.
Pendjari National Park
A savanna park in the far north, usually visited in the dry season for game viewing. CDC's malaria advice covers it, and its meningococcal advice may apply from December to June, so check CDC's meningitis-belt map with the clinic.
Crossing to Lomé or Lagos? Our Togo and Nigeria briefings cover the next border.
The Benin kit
- Picaridin 20% travel sprays: odorless in the coastal heat and quick to reapply at sunset. One 3.4 oz bottle covers about a week of daily use for one person.
- Permethrin 0.5% for clothes: for village and park stays, treat a long-sleeved shirt and trousers at home 48 hours before you fly. Clothing only, never skin.
- A travel bed net for rooms where screens or air conditioning fall short.
One more rule outlasts the trip. Any fever during or after your trip means a doctor visit, and you tell them you were in Benin. Malaria can show up weeks later.
Traveler questions
Do I need a yellow fever vaccine for Benin?
Benin requires proof of it. The CDC's recommendation is "Vaccine is recommended for all travelers ≥9 months old," and Benin's entry requirement is "Vaccine is required for all arriving travelers ≥9 months old." That applies on a direct flight from the US, so carry the yellow International Certificate of Vaccination with your passport. Book a travel clinic 4–6 weeks before you fly so the certificate is settled well before departure.
Do I need malaria pills for the Vodun Days in Ouidah?
The CDC recommends malaria prevention medicine for all of Benin, Ouidah included, and makes no exception for the dry season, when the January festival falls. The advice is the same if you're staying with family, and CDC notes that people visiting friends and relatives are at higher risk because they often skip prevention medicine. Which medicine fits you is a call for a travel clinic, made 4–6 weeks before departure with your full route. Our malaria-zone checklist covers the rest.
Is there dengue in Benin right now?
The CDC lists dengue for Benin. WHO counted Benin among African countries with dengue outbreaks in 2023 and with ongoing transmission into April 2024, but there are no 2025 or 2026 figures, and Benin isn't on the CDC's Global Dengue list. The mosquito that spreads dengue bites in daylight, so repellent goes on in the morning as well as at sunset.
Is there Zika in Benin?
The CDC's Zika page puts Benin among areas with mosquitoes but no reported Zika cases, and Benin's destination page doesn't list it. For those areas, CDC's advice to pregnant travelers is "Prevent mosquito bites during and after travel."
