💉 Vaccines: Required & Recommended
⚠️ Yellow Fever Certificate — Mandatory
Kenya requires proof of yellow fever vaccination for travellers arriving from yellow fever-endemic countries (most of sub-Saharan Africa, parts of South America). You must carry your International Certificate of Vaccination or Prophylaxis (ICVP). If you cannot produce it at the border, you may be vaccinated on the spot or refused entry. The WHO recommends all travellers to Kenya get vaccinated regardless of origin due to active transmission risk in western Kenya.
Recommended Vaccines for Kenya
| Vaccine | Risk / Reason | Notes |
|---|---|---|
| Yellow Fever | Required from endemic countries; recommended for all | Mandatory ICVP certificate — get 10+ days before travel |
| Hepatitis A | Contaminated food & water common outside Nairobi hotels | 2-dose series; single dose gives 1-year protection |
| Hepatitis B | Blood/body fluid exposure, medical procedures | 3-dose series over 6 months; combined A+B vaccine available |
| Typhoid | Contaminated food/water, especially upcountry | Oral (4 capsules) or injection; boosters every 2–5 years |
| Rabies (pre-exposure) | Dogs, monkeys, bats — common in rural areas | 3 doses before travel; simplifies post-exposure treatment |
| Meningococcal (MenACWY) | Required for Hajj/Umrah; recommended for long-stay | Single dose; booster every 5 years |
| Cholera (Dukoral) | Watery diarrhoea risk in outbreak areas, Mombasa coast | Oral vaccine; 2 doses 1–6 weeks apart |
| Polio booster | Kenya has had poliovirus detections in recent years | One adult booster if not vaccinated in last 10 years |
| Tetanus/Diphtheria/Pertussis | Wounds, dust, soil exposure on safari | Booster if >10 years since last dose |
| MMR (Measles-Mumps-Rubella) | Measles circulates in East Africa | 2 doses if born after 1957 and not previously vaccinated |
Tip: Visit a travel medicine clinic at least 6–8 weeks before departure. Many vaccines require multiple doses spread over weeks. The CDC and WHO both have online country-specific vaccine advisories you should check within 4 weeks of your trip date.
🦟 Malaria — Risk Zones & Prevention
Malaria is the single biggest infectious disease risk for travellers to Kenya. It is transmitted by Anopheles mosquitoes and is present year-round in most of the country. Plasmodium falciparum — the most dangerous and potentially fatal strain — is the dominant species.
Risk by Region
| Region / Area | Risk Level | Notes |
|---|---|---|
| Mombasa & Kenyan Coast | High | Year-round transmission; chloroquine resistance present |
| Lake Victoria basin / Kisumu | Very High | Highest transmission in Kenya; perennial risk |
| Western Kenya (Nyanza, W. Province) | High | Year-round; altitude provides little protection below 2,000m |
| Maasai Mara / Rift Valley (below 2,000m) | Moderate–High | Seasonal peaks April–June, Oct–Nov |
| Amboseli / Tsavo National Parks | Moderate | Risk lower but still present; take prophylaxis |
| Nairobi (above 1,800m) | Very Low | City itself is low-risk; no prophylaxis usually needed |
| Naivasha / Nakuru / Nanyuki (highland) | Low | High altitude reduces mosquito activity significantly |
| Mount Kenya / Aberdares (above 2,500m) | Negligible | Cold temperature prevents transmission |
Anti-Malarial Medications
Atovaquone-Proguanil (Malarone)
Pros: Fewest side effects, start 1–2 days before travel
Cons: Most expensive (~£3–5/day); not for long trips (>3 months)
Best for: Best for short trips (1–4 weeks)
Doxycycline
Pros: Cheapest option (~£0.20–0.50/day); also treats other infections
Cons: Sun sensitivity, stomach upset, can't take if pregnant
Best for: Good budget option for longer trips
Mefloquine (Lariam)
Pros: Weekly dosing convenient
Cons: Neuropsychiatric side effects; start 2.5 weeks early
Best for: Last resort — many doctors avoid it now
🛡️ Bite Prevention is Non-Negotiable
- Use DEET ≥30% repellent on exposed skin (reapply every 3–4 hours)
- Wear long sleeves and trousers after sunset
- Sleep under a permethrin-treated bed net (most budget lodges provide them)
- Stay in screened, air-conditioned rooms where possible
- If you develop fever within 3 months of returning home, get an immediate blood test
🔴 HIV & AIDS: What Travellers Need to Know
Kenya has one of the largest HIV-positive populations in the world — an estimated 1.4 million people living with HIV (2023), representing roughly 4.3% of the adult population. The government has made significant progress, with over 1.1 million people on antiretroviral therapy (ART). Transmission risk for tourists engaging in standard activities is extremely low, but travellers should be aware of risks during their stay.
How HIV is Transmitted
- Unprotected sexual intercourse
- Contaminated needles / syringes
- Blood transfusions (screened in Kenya but risk not zero)
- Mother to child during birth / breastfeeding
- NOT by casual contact, mosquitoes, or sharing food
Reducing Your Risk
- Use condoms for all sexual encounters
- Never share needles or syringes
- Carry a sterile needle kit for emergencies
- Use licensed dental/medical facilities
- Avoid tattoos or piercings with unsterile equipment
Post-Exposure Prophylaxis (PEP)
If you believe you have been exposed to HIV (unprotected sex, needlestick injury), you must start PEP within 72 hours — the sooner the better. PEP is a 28-day course of antiretroviral drugs that prevents HIV from establishing itself. Go immediately to the Aga Khan Hospital, Nairobi Hospital, or any major hospital emergency room and ask for PEP.
HIV Testing in Kenya
Kenya has made HIV testing widely accessible. If you want to test during your trip:
- VCT Centres (Voluntary Counselling & Testing) — available in all major towns, often free or very low cost
- Aga Khan Hospital, Nairobi — walk-in HIV testing, rapid result in 20 minutes
- Nairobi Hospital — comprehensive STI screening panels
- Pharmacy rapid tests — HIV self-test kits available at Nairobi pharmacies (OraQuick, Exacto) for ~KES 600–800 (~£3.50–5)
🌋 Rift Valley Fever & Tropical Diseases
Rift Valley Fever (RVF)
Rift Valley Fever is a viral zoonosis transmitted by mosquitoes and direct contact with infected animal blood or tissue. Kenya has had multiple outbreaks, particularly in the Rift Valley and northeastern regions during periods of heavy rainfall. The 2006–2007 outbreak killed over 150 people. Risk for tourists is low but not zero — avoid contact with slaughtered animals, raw meat, and unpasteurised animal products during outbreak periods. There is no licensed human vaccine (a research vaccine exists but is not commercially available). Monitor WHO outbreak alerts before travel.
Dengue Fever
Dengue is transmitted by Aedes aegypti mosquitoes (daytime biters) and is present in coastal Kenya (Mombasa) and increasingly in Nairobi. There is no specific treatment — rest, fluids, paracetamol (NOT ibuprofen/aspirin). Prevention: same DEET repellent and protective clothing as for malaria, but applied during the day as well as night. Kenya reported over 4,000 dengue cases in 2023.
Chikungunya
Also transmitted by Aedes mosquitoes, Chikungunya causes severe joint pain that can persist for months. Cases reported on the Kenyan coast. Prevention is the same as dengue — DEET during daytime hours. No vaccine or specific treatment.
Plague (Bubonic / Pneumonic)
Rare but present in Kenya's north-west. Transmitted by fleas from infected rodents. Risk for typical tourists is negligible. Avoid contact with dead rodents in rural areas. Seek immediate medical care if fever and swollen lymph nodes develop after rural exposure.
Schistosomiasis (Bilharzia)
Present in Lake Victoria and some other freshwater bodies in Kenya. Caused by parasitic worms in freshwater snails. Do NOT swim or wade in fresh water in rural Kenya unless it is a hotel pool with treated water. Infection often has no immediate symptoms. If you swam in suspect freshwater, see a doctor 6–8 weeks after return for a blood test.
Tuberculosis (TB)
Kenya has one of Africa's highest TB burdens (~130,000 new cases/year). Risk to short-term tourists is very low. Risk rises for those in prolonged close contact with local populations (healthcare workers, volunteers, long-stay travellers). If you will be in Kenya for 3+ months in a healthcare or community setting, discuss TB testing (IGRA blood test or tuberculin skin test) with your doctor before and after travel.
🦠 Typhoid, Traveller's Diarrhoea & Other Risks
Typhoid Fever
Contaminated food and water. High risk outside tourist hotels in Nairobi and upcountry areas. Vaccine recommended. Symptoms: sustained high fever, headache, abdominal pain. Treatment: antibiotics (note increasing drug resistance in East Africa).
Traveller's Diarrhoea
Most common health complaint for Kenya visitors. Caused by E. coli, Campylobacter, Salmonella. Usual duration: 3–5 days. Treat with oral rehydration salts. Carry Imodium for convenience (not if blood/fever present). Carry ciprofloxacin for severe cases — consult your doctor.
Rabies
Dogs, monkeys (common in Nairobi, Diani Beach), and bats. Always wash animal bites immediately with soap and water for 15 minutes. Seek medical care within 24 hours. If unvaccinated, you need rabies immunoglobulin (hard to source in Kenya — major Nairobi hospitals only) plus 5-dose vaccine series. Pre-exposure vaccination simplifies treatment greatly.
Altitude Sickness
Mount Kenya (5,199m) and trekking routes around it carry real altitude sickness risk. Ascend slowly, stay hydrated, consider acetazolamide (Diamox). Symptoms: headache, nausea, dizziness. Descend immediately if symptoms worsen or you develop shortness of breath at rest.
🚰 Water & Food Safety in Kenya
🚫 Do NOT drink tap water in Kenya
Tap water in Nairobi and other Kenyan cities is technically treated but often contaminated by aging pipes and infrastructure. Outside major cities, tap water is generally unsafe. Always drink bottled water, boiled water, or water purified with iodine tablets / SteriPen UV purifier.
✅ Safe to eat/drink
- Sealed bottled water (check seal is intact)
- Hot drinks made with boiled water (tea, coffee)
- Freshly cooked, piping hot food
- Fruits you peel yourself
- Vegetables cooked thoroughly
- Pasteurised dairy products (UHT milk)
❌ Avoid
- Ice in drinks (made from tap water)
- Raw salads / unpeeled fruits from street stalls
- Undercooked meat or seafood
- Unpasteurised dairy (fresh camel milk, goat milk)
- Food left sitting in the heat for hours
- Street food from hygienically questionable vendors
Despite the risks, Kenya has fantastic food culture — Kenyan restaurants in Nairobi and major tourist areas maintain high hygiene standards. Nyama choma (roasted meat), ugali, sukuma wiki, pilau rice, and samosas from reputable places are generally very safe.
