Yellow fever is circulating inland in Côte d'Ivoire. Malaria advice covers Abidjan and the beaches.
- Travel clinic CDC recommends medicine or vaccines for some areas · which ones
- No CDC travel notice for mosquito-borne disease
WHO's Africa office counted 14 confirmed yellow fever cases in forested districts in 2026, through early September, and every arriving traveler 9 months and older needs proof of the vaccine. The CDC also recommends malaria prevention medicine everywhere, from the Plateau and Cocody to Grand-Bassam and Assinie.
Are there mosquitoes in Côte d'Ivoire? Yes, in every month, and the CDC recommends malaria prevention medicine for the whole country, Abidjan, Grand-Bassam, Assinie and Yamoussoukro included. Côte d'Ivoire also requires proof of yellow fever vaccination from every arriving traveler 9 months and older, and in 2026 the virus has been circulating in forested districts inland.
Yellow fever: the card at the airport and the 2026 cases
WHO's Africa office counted 14 confirmed cases and 2 deaths from the start of 2026 through epidemiological week 34, after 5 confirmed cases in 2025. The 2026 cases came from eight forested health districts, and a rise in August detections pointed to "ongoing rather than localized transmission," WHO said. Thirteen of the 14 patients were unvaccinated, which is the plain case for having the vaccine. None of the districts WHO names is in Abidjan, Grand-Bassam, Assinie or Yamoussoukro.
What we suggest you do with this: the CDC recommends malaria medicine for all areas of Côte d'Ivoire, and its yellow fever recommendation is "Vaccine is recommended for all travelers ≥9 months old." The entry requirement is "Vaccine is required for all arriving travelers ≥9 months old," including on a direct flight from the US, so pack the yellow certificate. Book a travel-medicine appointment 4–6 weeks before departure; WHO says the vaccine protects most people from 10 days after the dose. Ask about meningococcal vaccine too, which CDC recommends for meningitis-belt areas of Côte d'Ivoire in the dry season, roughly December to June. CDC's Global Polio Level 2 notice also lists Côte d'Ivoire, and adults who had the childhood series may get a single lifetime booster.
Malaria after dark, on the lagoons and at home
The CDC's wording is "CDC recommends that travelers going to Côte d'Ivoire take prescription medicine to prevent malaria." Transmission occurs in all areas, mostly chloroquine-resistant Plasmodium falciparum, with no exception for cities, beach resorts or the dry season, so a family home in Yopougon falls under the same advice as a business hotel on the Plateau. Travelers going home to see family are the ones malaria most often catches out. CDC notes that travelers visiting friends and relatives are at higher risk of malaria because they often skip prevention medicine.
Malaria mosquitoes bite from dusk to dawn, so put repellent on at sunset, wear long sleeves in the evening and sleep in an air-conditioned or screened room, or under a treated bed net. Abidjan, Grand-Bassam and Assinie sit between the ocean and the Ébrié and Aby lagoons, and lagoon-side guesthouses tend to see more mosquitoes after dark.
The CDC also lists dengue and Zika, spread by Aedes mosquitoes that bite in daylight, and WHO's Africa office counted more than 4,000 dengue cases from January 2023 to May 2024. Repellent over sunscreen in the morning covers that shift, as our dengue & Zika routine explains.
When to go
The main dry season, roughly December to March, tends to bring the fewest mosquitoes, and it is when many families visit for the holidays. The long rains, roughly May to July, tend to be the worst, with shorter rains around October and November. In 2026, heavy rain from mid-May flooded Greater Abidjan. Malaria medicine and the certificate apply in every month.
Where you're going
Abidjan: Plateau, Cocody, Marcory & Zone 4
Inside the CDC's malaria advice with no city exception, whether you're in a Plateau business hotel or with family in Cocody. Abidjan was the center of the 2023–24 dengue outbreak, so wear repellent by day as well as at dusk.
Grand-Bassam
The old colonial town and its beaches, between the ocean and the lagoon east of Abidjan. Malaria advice applies, so ask whether your room has a bed net or screens before you book.
Assinie
Weekend beach and lagoon resorts toward the Ghana border, under the same malaria advice. Lagoon-side rooms tend to see more mosquitoes after dark, so put repellent on before sunset drinks.
Yamoussoukro
The capital, home of the Basilica of Our Lady of Peace. None of the yellow fever districts WHO has named in 2025–26 is here, and the malaria advice and the entry certificate apply as everywhere else.
The State Department advises against travel to the northern border region, as reported; check the current advisory. Crossing into Ghana? Our Ghana briefing covers its Upper West yellow fever notice.
The Côte d'Ivoire kit
- Picaridin 20% travel sprays: odorless in the lagoon humidity and quick to reapply at sunset.
- Permethrin 0.5% for evening clothes, applied at home 48 hours before you fly. It goes on clothing, never skin.
- A treated travel bed net for a guesthouse or family room without screens or air conditioning.
What travelers report
Paraphrased from a TripAdvisor review of a Grand-Bassam guesthouse and linked so you can read it in full. It isn't dated, and conditions vary by room and season.

A guest said the rooms were clean and air-conditioned and that it was the only place they had stayed in the region with mosquito nets above the beds. 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 Côte d'Ivoire. That holds for a year after you get home.
Traveler questions
Do I need a yellow fever vaccine for Côte d'Ivoire?
Côte d'Ivoire requires proof of it. The CDC's recommendation is "Vaccine is recommended for all travelers ≥9 months old," and the 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 certificate with your passport. WHO says the vaccine protects most people from 10 days after the dose, so book a travel clinic 4–6 weeks before you fly.
Is the 2026 yellow fever outbreak near Abidjan?
WHO's Africa office reported the 2026 cases from forested areas in eight health districts, naming Doropo, Téhini, Danané and Toulepleu, and none of the districts it names is in Abidjan, Grand-Bassam, Assinie or Yamoussoukro. It counted 14 confirmed cases and 2 deaths through epidemiological week 34 and described the transmission as ongoing. The CDC has no yellow fever travel notice for Côte d'Ivoire, and the entry requirement applies wherever you go in the country.
Do I need malaria pills if I'm staying with family in Abidjan?
The CDC recommends malaria prevention medicine for all of Côte d'Ivoire and makes no exception for cities, beach resorts or the dry season, so a family home in Abidjan falls under the same advice as a hotel. CDC notes that travelers visiting friends and relatives are at higher risk of malaria because they often skip prevention medicine. 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.
Is there dengue or Zika in Côte d'Ivoire?
The CDC lists both. WHO's Africa office counted more than 4,000 dengue cases from January 2023 to May 2024, and Côte d'Ivoire isn't on the CDC's Global Dengue list. CDC's Zika page puts the country among areas with current or past transmission but no outbreak, and tells pregnant travelers to "Talk to a health care provider about potential risks. If you decide to travel, prevent mosquito bites and sexual exposure to Zika." Both viruses spread through mosquitoes that bite by day, so repellent goes on in the morning too.
