Tanzania travel health
Sources checked
Overview
Tanzania (mainland and the Zanzibar islands) poses a mix of routine travel-health needs (vaccinations, food‑/water‑safety, insect‑bite avoidance) and location‑specific risks (malaria below about 1,800 m, freshwater schistosomiasis, and ongoing cholera and poliovirus detections in parts of the country). Entry and public‑health screening rules have changed recently: Zanzibar requires a mandatory inbound travel insurance policy, and mainland Tanzania now requires an online Traveller’s Health Surveillance Form (AfyaMsafiri) for arrivals. Travelers should plan vaccinations and malaria prevention well before departure and carry proof of any required documents. U.S. CDC – Tanzania travel page.
Key practical preparation
Book a travel‑health appointment 4–8 weeks before travel to review routine vaccines and required or recommended travel vaccines, discuss malaria prevention for your specific itinerary and obtain any necessary documentation for entry (see yellow fever and health‑form rules). Carry proof of travel/health insurance that covers emergency evacuation — Zanzibar enforces a mandatory inbound policy for visitors. Zanzibar advisory (Zanzibar Insurance Corporation) · U.S. Department of State – Tanzania travel advisory.
Vaccinations and entry requirements
Separate legal/administrative entry rules from medical recommendations. Below are the common vaccine topics travelers and clinicians ask about for Tanzania; follow the linked guidance for age, pregnancy and prior‑vaccination exceptions.
Routine vaccines (all travellers)
Make sure routine immunizations are up to date: measles‑mumps‑rubella (MMR), diphtheria‑tetanus‑pertussis (DTP/Tdap/Td), varicella, polio, and seasonal influenza as appropriate. Measles is circulating globally and travelers should meet the international travel timetable for MMR. U.S. CDC – routine vaccine recommendations.
Hepatitis A and typhoid
Hepatitis A vaccine is recommended for all unvaccinated travelers (age ≥1 year); an initial dose should be given before travel. Typhoid vaccine is recommended for most travelers to Tanzania, especially if you will eat outside major hotels/restaurants or visit smaller towns and rural areas. U.S. CDC – Hep A / Typhoid guidance.
Hepatitis B
Hepatitis B vaccination is recommended for travelers who might have sexual contact with new partners, require medical care, or have potential occupational exposure; otherwise routinely recommended where not previously completed. U.S. CDC – Hepatitis B guidance.
Rabies
Rabies is present in domestic dogs and some wildlife. Pre‑exposure vaccination is recommended for travelers at higher risk (long stays, remote travel, extensive outdoor activity, children, occupational exposure) because prompt post‑exposure prophylaxis (PEP) may be limited outside major urban centres. Even if pre‑exposure vaccine is given, wounds still need urgent cleansing and medical assessment. U.S. CDC – rabies · Tanzania Public Health Bulletin – animal bites/rabies data.
Yellow fever (vaccine & entry rules)
Yellow fever vaccine is generally not required for direct travel from the United States, but Tanzania requires a valid International Certificate of Vaccination or Prophylaxis (ICVP) from travellers arriving from or transiting (>12 hours or disembarking) through countries with yellow fever transmission. If you will travel from or through a risk country, get vaccinated at least 10 days before departure. Carry your ICVP when it applies. U.S. CDC – yellow fever (country notes) · Tanzania / ICAO – port health / yellow fever requirement.
Polio
Poliovirus detections (environmental samples of circulating vaccine‑derived type 2) have been reported in Tanzania in the past year. Travelers should ensure their polio vaccinations are up to date; adults who completed childhood series may be advised a single inactivated‑polio vaccine (IPV) booster before travel in some circumstances. Discuss polio status with your clinician if you will work in high‑risk settings or travel to areas with poor sanitation. U.S. CDC – polio guidance · UK TravelHealthPro / NaTHNaC – polio updates · WHO – polio committee statement.
Cholera vaccine (selective)
Authorities report active cholera transmission in Tanzania and regional cholera activity is elevated. Cholera vaccination may be considered for travelers (including children) who will be visiting areas with active transmission or who have increased risk of severe disease. Routine prevention focuses on safe food and water, hand hygiene and prompt medical care for severe diarrhoea. U.S. CDC – cholera in Tanzania · WHO – cholera upsurge and epidemiological updates · Tanzania Public Health Bulletin.
Other health risks and prevention
Non‑vaccine threats and practical prevention depend on where you go, the season, and activities you plan. The items below are those most relevant to travellers to Tanzania.
Malaria
Malaria transmission occurs in all areas of Tanzania below about 1,800 meters elevation (this includes most safari destinations and Zanzibar). Use insect‑avoidance measures (lice/mesh screens, DEET‑containing repellents, permethrin‑treated clothing and bed nets) and take an appropriate prescription antimalarial for your itinerary. Recommended prophylaxis options include atovaquone‑proguanil, doxycycline, mefloquine or tafenoquine; choice depends on medical history, pregnancy status, resistance patterns and side‑effect profiles. Start and stop prophylaxis according to the drug’s schedule and talk to your clinician about options. U.S. CDC – malaria (country notes) · CDC – malaria risk and prophylaxis considerations.
Waterborne and foodborne illness
Diarrhoeal illness (including cholera during outbreaks), hepatitis A and typhoid are risks from contaminated food or water. Practice safe food and water precautions: bottled or boiled water, avoid raw shellfish and undercooked street foods, and frequent hand hygiene. Seek care promptly for severe diarrhoea or signs of dehydration. U.S. CDC – food and water safety.
Freshwater exposure (schistosomiasis)
Schistosomiasis occurs in freshwater in many parts of Tanzania. Avoid swimming, wading or other contact with freshwater lakes, rivers and slow‑moving streams unless you have advice and plans for testing/treatment after exposure. U.S. CDC – schistosomiasis.
Insect‑borne viral infections (dengue, Rift Valley fever, others)
Dengue occurs in Tanzania and presents as fever with severe muscle/joint pain; no widely available vaccine for travelers is recommended for routine use. Protect against daytime and nighttime mosquito bites. Rift Valley fever and other vector‑borne illnesses have been recorded in the region during animal outbreaks—avoid contact with sick animals and animal tissues. U.S. CDC – dengue and vector precautions.
Roads, remote settings and medical care
Road traffic injuries are a common hazard in low‑ and middle‑income settings; ambulance and hospital services may be limited outside cities. Carry comprehensive travel health insurance that covers emergency evacuation and repatriation, and have local emergency contacts. Zanzibar enforces a mandatory inbound travel insurance policy for visitors. U.S. Department of State – medical care and insurance advice · Zanzibar advisory (mandatory inbound travel insurance).
Current health alerts
Only active, verifiable developments are listed below. Check official sources near departure for last‑minute changes.
Cholera: active transmission in parts of Tanzania
Public‑health reports show active cholera transmission in Tanzania and regional upsurges in 2025–2026; travelers to areas with active transmission should follow strict food‑ and water‑safety measures, and consider cholera vaccine when recommended for specific itineraries or for people at higher risk of severe disease. If you develop severe watery diarrhoea, seek urgent medical care. U.S. CDC – cholera in Tanzania · WHO – cholera upsurge and epidemiological updates · Tanzania Public Health Bulletin (recent cholera data).
Poliovirus detections (environmental samples)
Circulating vaccine‑derived poliovirus type 2 (cVDPV2) has been detected in environmental samples in Tanzania (Mwanza area in 2025); countries with recent detections are subject to enhanced polio control measures. Travelers should ensure polio vaccination is current; some travelers at higher risk may be advised a booster dose. TravelHealthPro / NaTHNaC – polio updates · WHO – polio IHR Emergency Committee · U.S. CDC – polio advice.
Border health procedures and forms (mainland and Zanzibar)
Mainland Tanzania has introduced an online Traveller’s Health Surveillance Form (AfyaMsafiri) that must be completed before departure or on arrival for mainland entry; Zanzibar maintains separate advisories and requires mandatory inbound travel insurance from the Zanzibar Insurance Corporation for non‑residents. Check the AfyaMsafiri portal and the Zanzibar insurance portal (or embassy advisories) before travel. Tanzania AfyaMsafiri portal (Traveller's Health Surveillance Form) · Zanzibar advisory – mandatory inbound travel insurance · U.S. Department of State – entry/insurance notes.
Before you travel
Plan early, get expert advice, and carry documentation.
Preparation checklist
At least 4–8 weeks before travel: 1) see a travel‑health clinician to review and update vaccines (MMR, hepatitis A, typhoid, hepatitis B, rabies as indicated, and polio if advised), 2) arrange malaria chemoprophylaxis for destinations below 1,800 m, 3) confirm how yellow fever rules apply to your route and obtain an ICVP if needed, 4) purchase adequate travel health insurance (Zanzibar requires a local inbound policy), and 5) complete any required public‑health forms (AfyaMsafiri for mainland Tanzania or the Zanzibar traveller form where applicable). Keep printed and digital copies of vaccine records and insurance. U.S. CDC – Tanzania travel advice · AfyaMsafiri health form (Tanzania Ministry of Health) · Zanzibar inbound insurance advisory.
