Honest about the risks, and specific about what prevents each one.
Malaria
Present below 2,500 m across the country, including every major game park. Chloroquine-resistant P. falciparum โ the form that kills โ is the dominant type.
Prevention Tablets, chosen against your itinerary and your other medications. Plus bite prevention: repellent, long sleeves at dusk, a treated net. And remember it can appear up to a year after you get home.
Road safety
The Government of Canada is blunt: major road safety issues, fatal accidents common, particularly on the Mombasa Highway. Potholes, stray animals, speeding, ignored traffic law and poor lighting. CDC notes crashes are the number one killer of healthy travellers abroad.
Prevention No intercity roads after dark. Use a driver from your lodge or operator rather than self-driving. Seatbelts in the back too.
Schistosomiasis
A parasite in fresh water. The Government of Canada notes most travellers are at low risk, but there is no vaccine and no preventive medication โ the only protection is staying out.
Prevention No wading, swimming or bathing in lakes, rivers or dams, however inviting. Chlorinated pools are fine, and so is the sea.
Dengue and chikungunya
Both named by the Government of Canada, both mosquito-borne, and the mosquitoes that carry them bite in daylight โ particularly around sunrise and sunset, which is exactly when the game drives happen. Chikungunya joint pain can last months or years.
Prevention Repellent through the day, not just at dusk. Long sleeves for the early and late drives.
Rift Valley fever
The Government of Canada names it: spread by contact with infected animals, mosquito bites or unpasteurised dairy, severe flu-like illness, occasionally fatal, no vaccine. Risk described as generally low for most travellers.
Prevention No unpasteurised milk. Avoid livestock markets and slaughter areas.
Animals and rabies
Rabies is present in dogs and wildlife. On safari the animal risk is managed by your guide; in towns and villages it is the street dogs, and children are the ones who approach them.
Prevention No touching dogs, cats or monkeys. Any bite, scratch or lick on broken skin: wash for fifteen minutes and seek medical advice the same day.
Getting treated
The Government of Canada notes good medical facilities in Nairobi but standards elsewhere that vary and can be very limited, and that facilities may require proof of insurance or payment up front before treatment starts.
Prevention Travel insurance with medical evacuation, and the policy number saved offline. Ask your operator what their evacuation arrangement actually is.
