Travel Health Guide: Senegal (2026): Yellow Fever, Year-Round Malaria, and the Alerts to Watch
Senegal is one of the few destinations where a vaccine can be a legal entry requirement, not just a recommendation. Yellow fever vaccination is recommended for essentially every traveler nine months and older, and proof of it is required if you are arriving from (or spent more than 12 hours in transit in) another country with yellow fever risk. On top of that, malaria transmission occurs throughout the entire country year-round, so nearly every traveler needs prescription antimalarial medication plus daily mosquito-bite prevention. In my practice, the travelers who run into trouble with Senegal are usually the ones who treated it like a beach trip to Dakar and skipped the malaria pills because "the city is low risk." That is a mistake. Get your yellow fever shot at least 10 days before departure, start an antimalarial, confirm your routine vaccines including MMR and a polio booster, and buy travel insurance that covers medical evacuation to Europe. The rest is detail, and I will walk you through it.
Quick Facts
- Region: West Africa, on the Atlantic coast; capital is Dakar
- CDC malaria risk: Present throughout the entire country, all year
- Yellow fever: Recommended for all travelers 9 months and older; certificate required if arriving from a country with yellow fever transmission risk (including 12+ hour layovers)
- Recommended vaccines: Yellow fever, hepatitis A, hepatitis B, typhoid, and meningococcal for most travelers; routine vaccines and a polio booster for everyone
- Meningitis belt: Yes, Senegal sits in the seasonal meningitis belt; highest risk in the dry season (roughly December to June)
- 2026 alerts to watch: A Rift Valley fever outbreak in northern Senegal (declared September 2025) and an ongoing dengue situation since 2024
- Tap water: Not reliably safe for visitors; stick to bottled or treated water
- Travel insurance: Strongly recommended, with medical evacuation coverage of at least $100,000 (complex cases are typically evacuated to Paris)
Overview: A Rewarding Destination That Rewards Preparation
Senegal is a genuinely welcoming, culturally rich destination, from the music and markets of Dakar to the pink waters of Lac Rose and the history of Gorée Island. It is also a full-precaution travel health destination, which means the prep list is longer than for a Caribbean beach week. That is not a reason to skip Senegal. It is a reason to plan four to six weeks out instead of the night before.
Here is the honest clinical picture. The infectious risks that matter most are malaria (everywhere, all year), yellow fever (a real transmission risk and often a legal entry requirement), and the food-and-water illnesses that affect a large share of travelers to West Africa. Layered on top are seasonal and situational risks: meningococcal disease during the dry, dusty months, and two active outbreak stories in 2026 that deserve a paragraph each.
As a PA who has treated returning travelers, my approach to Senegal is to nail the non-negotiables first (yellow fever, malaria, routine vaccines) and then tailor the rest to your itinerary and season. A business traveler spending three days in a Dakar hotel and a volunteer spending three weeks in rural Casamance during the rainy season need the same core protection but very different risk counseling. Below, I break it down by category so you can see where you land.
Malaria in Senegal: Everywhere, All Year
Malaria transmission occurs throughout all of Senegal, in every region, throughout the year, which is why the CDC recommends antimalarial medication for essentially all travelers. This is the single most important health decision for your trip. The parasite is predominantly chloroquine-resistant Plasmodium falciparum, the most dangerous species, so older drugs like chloroquine are not effective here. The CDC lists four medications that work for Senegal: atovaquone-proguanil (Malarone), doxycycline, mefloquine, and tafenoquine (Arakoda).
Risk is not evenly distributed. The southern Casamance region, the southeastern Kedougou area, and the Senegal River valley in the north carry the heaviest malaria burden, while Dakar and the northern Sahel see lower but still real transmission. Seasonally, transmission peaks during and just after the rainy season, roughly July through November, with the highest intensity in October and November. Even so, cases occur in the dry season too, and "low risk" does not mean "no risk," which is why the recommendation is to protect yourself regardless of when or where in Senegal you go.
The two pieces work together: the pills and the bites. Antimalarial medication is not 100 percent protective on its own, so you also need to prevent bites, especially from dusk to dawn when the malaria-carrying Anopheles mosquito feeds. That means an EPA-registered repellent (DEET, picaridin, or IR3535), covering up in the evening, and sleeping under a net or in air-conditioned, screened rooms in higher-risk areas.
Get your antimalarial sorted before you fly. Wandr's clinicians review your destination, dates, and history and, if appropriate, call an antimalarial prescription in to your local pharmacy for pickup, so you can start it on schedule. Timing matters: Malarone starts 1 to 2 days before entering the malaria area, doxycycline 1 to 2 days before, and mefloquine at least 2 weeks before. Start your free pre-trip health check to see which option fits your trip.
Yellow Fever: Recommended for Everyone, Sometimes Legally Required
Yellow fever is where Senegal differs from most destinations, because the vaccine can be both a medical recommendation and a legal entry condition. The CDC recommends yellow fever vaccination for all travelers aged 9 months and older going to Senegal, reflecting a genuine transmission risk in the country. Separately, Senegal requires proof of yellow fever vaccination for travelers arriving from a country with risk of yellow fever transmission, and that includes travelers who have passed more than 12 hours in transit through such a country.
In practice, that means you should plan on the vaccine and carry the certificate. The yellow fever vaccine must be given at an authorized vaccination center, and it takes effect 10 days after the dose, which is also when the International Certificate of Vaccination (the "yellow card") becomes valid. Since 2016, the certificate is valid for life, so if you have been vaccinated before, you do not need a booster for entry purposes. Bring the physical card; border officials can ask to see it.
One important caveat: yellow fever vaccine is a live vaccine and is not appropriate for everyone, including some people who are pregnant, immunocompromised, or have certain allergies. If that is you, a clinician can assess whether a medical waiver letter is appropriate. This is exactly the kind of judgment call worth making with a provider rather than guessing, so build in time for it.
Because yellow fever vaccination in the US is handled at designated centers rather than at every pharmacy, confirm the logistics early. Wandr can help you map out your full vaccine timeline so nothing falls through the cracks. See your recommended vaccines for Senegal and get the sequence right.
Other Recommended Vaccines: Hepatitis, Typhoid, and Meningococcal
Beyond yellow fever, the CDC recommends several vaccines for most travelers to Senegal: hepatitis A, hepatitis B, typhoid, and meningococcal disease, plus staying current on routine immunizations and getting a polio booster if you have not had one as an adult. Hepatitis A and typhoid both spread through contaminated food and water, which is a meaningful route of infection in West Africa, so these two are high-value for nearly every itinerary, including short city stays.
Meningococcal vaccine deserves special attention because of geography and season. Senegal sits in Africa's "meningitis belt," the band of countries that experience seasonal epidemics of meningococcal disease during the dry, dusty months, roughly December through June. The dry-season Harmattan winds and low humidity are thought to help the bacteria spread. If your trip falls in that window, or you will be in close-contact settings, meningococcal vaccination moves from "consider it" to "strongly recommended."
Rabies is worth a conversation for specific travelers: long stays, rural work, cyclists and runners, animal handlers, and young children, since dogs are the main source of rabies in the region and medical care can be far away. Most short-stay leisure travelers will not need pre-exposure rabies vaccine, but everyone should know the rule after any bite or scratch: wash the wound thoroughly and seek medical care immediately, because rabies is essentially always fatal once symptoms begin but is preventable with prompt treatment.
Here is the workflow distinction that trips people up. Travel vaccines like hepatitis A, typhoid, and meningococcal are administered by a pharmacist at a partner pharmacy under standing orders, no separate doctor's prescription needed. Wandr books that appointment for you at a partner pharmacy near you, and the pharmacist administers the vaccines on-site. Yellow fever is the exception, since it must be given at an authorized yellow fever center. Book your travel vaccine appointment through Wandr and skip the game of calling pharmacies to check what is in stock.
Two 2026 Alerts Worth Knowing About
Senegal has two active outbreak stories in 2026 that a good travel health plan should account for, even though neither should scare you off the trip.
Rift Valley fever (northern Senegal). In September 2025, Senegal's Ministry of Health declared a Rift Valley fever outbreak concentrated in the northern livestock regions, especially Saint-Louis, along with Matam and Louga near the Senegal River and the Mauritania border. Reports through late 2025 counted several hundred human cases and dozens of deaths, and the US Embassy in Dakar issued health alerts about it. Rift Valley fever spreads mainly through contact with the blood, fluids, or tissues of infected animals (and to a lesser degree through mosquito bites), so travelers to the northern river valley should avoid contact with livestock and slaughtering, avoid unpasteurized milk, and use mosquito protection. Most leisure itineraries centered on Dakar and the coast carry low risk, but if your trip includes the north, factor this in.
Dengue. Senegal has seen sustained dengue activity since a large outbreak began in early 2024, with cases reported across many regions including Dakar, Thies, Fatick, Kaolack, and the southeast. Dengue is spread by day-biting Aedes mosquitoes, the same daytime feeders responsible for chikungunya and Zika, so daytime repellent use matters here in a way it does not for malaria alone. There is no dengue medication and the vaccine is not recommended for most US travelers, which makes bite prevention your only real tool. The practical takeaway: in Senegal you need to protect against bites both during the day (dengue) and at night (malaria), which effectively means all day.
Food, Water, and the Illness Most Travelers Actually Get
Traveler's diarrhea is, statistically, the health problem you are most likely to encounter in Senegal, far more common than any exotic virus. It comes from food and water contaminated with bacteria, and West Africa is a higher-risk region for it. Tap water in Senegal is not reliably safe for visitors, so the standard guidance applies: drink bottled or properly treated water, skip ice of unknown origin, eat food that is thoroughly cooked and served hot, and be cautious with raw produce and street food you cannot verify was washed in safe water. "Boil it, cook it, peel it, or forget it" is a cliché because it works.
Even careful travelers get caught, so the smart move is to travel prepared. Oral rehydration salts are the backbone of treatment because dehydration, not the infection itself, is what turns a bad day into an emergency. For moderate to severe cases, a standby antibiotic prescribed before your trip can shorten the illness, and an anti-motility medication like loperamide can help you get through a travel day. A clinician can help you assemble the right kit for your itinerary; Wandr's team can review your trip and, where appropriate, call the relevant prescriptions in to your local pharmacy for pickup. Build your pre-trip health plan so you are not hunting for a pharmacy while you are sick.
Beyond stomach bugs, respect the heat and sun. Much of Senegal is hot and, inland, dry, and heat exhaustion sneaks up on travelers who are active in the middle of the day. Hydrate ahead of thirst, seek shade during peak sun, and use a broad-spectrum sunscreen.
Healthcare and Why Insurance Is Not Optional Here
Dakar has the best medical care in the region, with private clinics that can stabilize serious illness and injury, but Senegal has a stark capital-versus-country divide: roughly 70 percent of the nation's doctors are based in Dakar, and specialist care and advanced diagnostics thin out quickly outside the city. For anything requiring complex surgery, sustained intensive care, or a specialist who is not available locally, the practical answer is often medical evacuation, and the most common evacuation destination for serious cases is Paris.
That is why travel insurance with medical evacuation coverage is not a nice-to-have for Senegal. The US State Department specifically recommends supplemental insurance that covers medical evacuation, and a reasonable target is at least $100,000 in medical coverage plus evacuation, because an air ambulance out of West Africa can run $30,000 to $100,000 or more out of pocket. If you are traveling to rural areas, the case for robust coverage is even stronger, since you may need transport to Dakar before any onward evacuation.
Confirm your policy covers both medical treatment and emergency evacuation, and that it applies to the specific regions on your itinerary. Get travel insurance through Wandr before you go, so a bad day abroad does not become a financial catastrophe on top of a medical one.
Health and Safety Tips for Senegal
- Start your malaria medication on schedule and finish the full course after you return, including the doses recommended for after you leave the malaria area. Stopping early is a common reason people still get sick.
- Use repellent day and night. Malaria mosquitoes bite at night; dengue mosquitoes bite by day. In Senegal you need both.
- Carry your yellow fever card. If you have any layovers in yellow-fever-risk countries, you may be asked to show proof on arrival.
- Drink bottled or treated water, avoid ice of unknown origin, and be selective with raw food.
- Mind the dry-season dust and heat. The Harmattan season brings dust that can irritate airways and correlates with meningococcal risk.
- In the north, avoid livestock contact given the 2025 to 2026 Rift Valley fever activity, and skip unpasteurized dairy.
- Know the rabies rule: wash any animal bite or scratch thoroughly and seek care immediately.

Frequently Asked Questions
Do I need malaria pills for Senegal? Yes. Malaria is present throughout all of Senegal year-round, and the CDC recommends antimalarial medication for essentially all travelers. Chloroquine-resistant Plasmodium falciparum predominates, so effective options are atovaquone-proguanil (Malarone), doxycycline, mefloquine, or tafenoquine. Combine the pills with mosquito-bite prevention, since no antimalarial is 100 percent protective on its own.
Is the yellow fever vaccine required for Senegal? Yellow fever vaccination is recommended for all travelers 9 months and older. It is also legally required if you arrive from a country with yellow fever transmission risk, including layovers over 12 hours in such a country. Get vaccinated at an authorized center at least 10 days before departure and carry the certificate, which is now valid for life.
What vaccines do I need for Senegal? For most travelers, the CDC recommends yellow fever, hepatitis A, hepatitis B, typhoid, and meningococcal vaccines, plus current routine immunizations and a polio booster. Meningococcal is especially important during the dry season (roughly December to June) because Senegal is in Africa's meningitis belt. Rabies vaccine is worth discussing for longer or rural trips.
Is it safe to drink the tap water in Senegal? No, tap water in Senegal is not reliably safe for visitors. Drink bottled or properly treated water, avoid ice of uncertain origin, and eat food that is cooked and served hot. Traveler's diarrhea is the most common illness affecting visitors to the region, so packing oral rehydration salts and a standby treatment plan is smart.
When is malaria risk highest in Senegal? Transmission occurs all year but peaks during and just after the rainy season, roughly July through November, with the highest intensity in October and November. The southern Casamance, southeastern Kedougou, and the Senegal River valley carry the heaviest burden, but risk exists nationwide, including in and around Dakar, so protection is recommended regardless of season.
Should I worry about the Rift Valley fever and dengue outbreaks in 2026? Both are worth awareness rather than alarm. Rift Valley fever activity since September 2025 has centered on the northern livestock regions near the Senegal River; avoid animal contact and unpasteurized dairy if you travel north. Dengue has been active since 2024 across many regions including Dakar, so use daytime mosquito protection. Most Dakar-and-coast leisure trips are low risk for Rift Valley fever.
Do I need travel insurance for Senegal? Strongly recommended. Quality specialist care is concentrated in Dakar, and complex cases are often evacuated to Paris, with air-ambulance costs that can exceed $100,000 out of pocket. The US State Department advises carrying supplemental insurance that covers medical evacuation. Aim for at least $100,000 in medical coverage plus evacuation, and confirm it applies to every region on your itinerary.
How far in advance should I prepare for a trip to Senegal? Plan at least four to six weeks ahead. Yellow fever vaccine must be given at least 10 days before departure to be valid, some vaccine series take time, and mefloquine should start about two weeks before you enter a malaria area. Starting early also leaves room to handle a yellow fever waiver or an alternate antimalarial if you cannot take the first choice.
