Senegal travel health
Sources checked
Overview
Prepare for mosquito‑borne infections (malaria, dengue), routine vaccine‑preventable illnesses and periodic local outbreaks (most recently diphtheria). Yellow fever certification may be required for some arrivals. Rural and remote areas have more limited medical services and higher risk for animal exposures and vectorborne disease; plan wound care, evacuation insurance and medicines before travel.
Key preparation and exposure considerations
Talk with a travel‑health clinician 4–6 weeks before departure to review routine immunizations, antimalarial options and any specialist protection you may need for occupational or adventurous activities. Consider travel medical and evacuation insurance and arrangements for rapid care if you will be in remote regions. U.S. CDC: Senegal travel health.
Vaccinations and entry requirements
This section separates legal/administrative entry rules from routine and recommended vaccine protection for travellers. Follow the destination’s documentary rules even if they duplicate clinical recommendations.
Yellow fever — entry rules and recommendations
Senegal requires a valid International Certificate of Vaccination against yellow fever for travellers aged 9 months or older who are arriving from, or who have transited through, countries with risk of yellow fever transmission; the vaccine takes effect 10 days after vaccination. The certificate’s validity follows the International Health Regulations. Clinically, yellow fever vaccination is also recommended for many travellers to Senegal; discuss contraindications (pregnancy, certain immune conditions) with your clinician. Institut Pasteur: Senegal travel advice (Fr.) WHO: IHR / yellow fever certificate rules.
Routine and widely recommended vaccines
Ensure routine immunizations are up to date (diptheria‑tetanus‑pertussis, polio, measles/MMR, varicella, influenza as appropriate). Hepatitis A and typhoid vaccines are routinely recommended for most travellers because food‑ and waterborne infections are common. Hepatitis B vaccination is recommended for extended stays, sexual contact, or medical/surgical procedures. For authoritative lists and age/interval details see country guidance. U.S. CDC: vaccine recommendations for Senegal.
Meningococcal vaccine (seasonal / location‑specific)
Parts of Senegal lie in the sub‑Saharan “meningitis belt.” During the dry season (roughly December–June) a quadrivalent meningococcal conjugate vaccine (MenACWY) is recommended for travellers to areas inside the belt or for those who will have close, prolonged contact with local communities. Check timing and target regions with a travel clinician. U.S. CDC: meningococcal recommendation WHO Regional Office for Africa: meningitis belt.
Rabies
Rabies is present in domestic and wild mammals in Senegal. Pre‑exposure vaccination should be considered for travellers with likely animal contact (veterinary work, long rural stays, caving, wildlife handling) because post‑exposure treatment may be limited or delayed. Anyone with an animal bite must seek urgent medical evaluation for post‑exposure prophylaxis. CDC Yellow Book: rabies guidance U.S. CDC: rabies, Senegal.
Other health risks
Practical prevention depends on where and what you will be doing: city tourism, rural stays, market visits, farming, trekking, or extended community work each carry different exposures.
Malaria
Malaria (primarily Plasmodium falciparum) is endemic in Senegal; risk exists in most areas and transmission is seasonal in many districts with peaks after rains. CDC recommends that travellers to Senegal use prescription antimalarial chemoprophylaxis and strict mosquito‑bite avoidance measures (bed nets, repellents, clothing). Drug choices and duration depend on individual medical history and itinerary; discuss options (atovaquone‑proguanil, doxycycline, mefloquine, tafenoquine where appropriate) with your clinician. CDC: malaria by country (Senegal) U.S. CDC: Senegal travel health.
Dengue and other arboviruses
Dengue occurs in Senegal and regional surveillance in 2026 shows higher‑than‑average dengue activity; travellers should use aggressive daytime and evening mosquito protection because dengue is spread by Aedes mosquitoes and there is no routine vaccine for most travellers. Also be aware of other mosquito‑borne threats (e.g., chikungunya) depending on local circulation. Global Dengue Observatory: country dengue data WHO Weekly Epidemiological Record: dengue surveillance.
Rift Valley fever and other zoonoses
Rift Valley fever (RVF) caused animal and human cases in 2025 in northern regions (Saint‑Louis, Matam and others); that outbreak was managed and public‑health surveillance strengthened and was declared over in early 2026. Zoonotic viral haemorrhagic fevers and tick‑borne Crimean‑Congo haemorrhagic fever have been detected in the region; avoid contact with sick or dead animals and follow local advisories. WHO / Joint FAO‑WHO/WOAH: RVF rapid risk assessment Frontiers: RVF 2025 analysis (Senegal).
Food‑ and water‑borne infections, schistosomiasis
Traveller’s diarrhea, hepatitis A and typhoid fever are common considerations; vaccination, safe food/water practices and hand hygiene reduce risk. Freshwater exposure (lakes, rivers) can transmit schistosomiasis — avoid bathing or wading in freshwater where transmission is possible. U.S. CDC: food/water, schistosomiasis, Senegal.
Health system and travel logistics
Specialized care is concentrated in Dakar and larger regional hospitals; rural clinics have limited diagnostics and some essential medicines. Travellers are advised to carry an adequate supply of routine prescriptions, consider evacuation insurance, and know how to reach local emergency services. CDC in Senegal: public health and health systems.
Current health alerts
Only alerts with current, corroborated evidence are listed here. Check these sources again immediately before travel because outbreak status can change quickly.
Diphtheria — active outbreak (October 2026)
Health authorities and regional surveillance report an active diphtheria outbreak in multiple regions of Senegal in 2026; cases and some deaths have been notified across several health districts. Travellers should ensure up‑to‑date diphtheria‑containing vaccination (DTP/Tdap) and seek prompt care for throat illness, fever or difficulty breathing. Follow local public‑health instructions. WHO Regional Office for Africa: weekly bulletin (Senegal) ECDC: diphtheria in Africa (includes Senegal).
Rift Valley fever — previous 2025 outbreak, no ongoing national emergency
A Rift Valley fever event with both animal and human cases occurred in late 2025 (northern and central regions). That event was managed by health and animal‑health authorities and was reported closed in early 2026; however, RVF is a recurrent risk in affected areas, so avoid contact with livestock blood/fluids and follow local animal‑health advisories. WHO / FAO/WOAH RVF assessment (2025) Frontiers: 2025 RVF in Senegal.
Dengue activity — elevated regional activity in 2026
Surveillance dashboards and WHO reporting indicate above‑average dengue activity in parts of West Africa in 2026. Travellers should use strong mosquito protection (repellent, treated nets for sleeping in basic accommodation) and seek medical care for febrile illness. Global Dengue Observatory: country-level dengue trends WHO WER: dengue surveillance.
Before you travel
Do these practical steps before departure:
Checklist
1) See a travel‑health clinician 4–6 weeks before travel to review vaccines (yellow fever certificate if required), malaria prophylaxis and any pre‑exposure rabies vaccination; 2) pack an insect repellent (DEET or picaridin), a portable mosquito net (if staying in basic accommodation), a first‑aid kit and your routine medicines; 3) arrange travel health insurance and know how to contact local emergency services; 4) avoid freshwater exposure and animal contact, and follow food‑safety practices; 5) monitor official travel and health notices for updates.
