Malaria: the honest picture

The Okavango Delta is a malaria area. The mosquitoes that carry the parasite (Anopheles) breed in water. The Delta is water. Malaria risk peaks November–May (rainy season, when mosquitoes breed fastest) and is lower June–October (dry season, fewer mosquitoes). But it is present all year. If you are visiting June–August (peak flood, best season), your risk is lower than if you visit November–March, but not zero.

A travel clinic can assess your personal risk and recommend prophylaxis. Options vary by country and individual health. This site does not give medical advice. Take it seriously. Untreated malaria can be fatal. Treated, it is manageable. See a clinic.

Prophylaxis options

Your travel clinic will discuss antimalarial options (e.g., atovaquone-proguanil, doxycycline, mefloquine). Each has side effects and contraindications. The choice depends on your health, allergies, and the clinic’s recommendation. Start prophylaxis before you arrive; take it as prescribed; continue after you leave. Do not skip doses or self-diagnose if you feel unwell during or after travel. Seek medical attention.

Yellow fever

Yellow fever vaccine is not required for entry to Botswana unless you are arriving from a yellow-fever country (parts of Africa or South America). If your itinerary includes other countries, ask your clinic. Botswana itself has no yellow fever risk.

Dengue and other mosquito-borne illnesses

Dengue is present in Botswana but rare in the Delta. Use DEET-based insect repellent and wear long sleeves at dawn and dusk. The repellent is most important at the foreshore and in thick vegetation.

Tap water and food safety

Tap water in Maun is safe to drink. Hotels provide bottled water as well. Food safety is high on organized tours; lunch is prepared on-site or by trusted operators. Street food is generally safe but use judgment. Wash your hands before eating.

Insider tip

Visit a travel clinic 4–6 weeks before travel. Take malaria prophylaxis seriously November–June. Yellow fever not required unless specified by your clinic. Ask about dengue repellent.

During and after your trip

If you develop fever, chills, or joint pain during or in the weeks after travel, seek medical attention immediately and tell the doctor you were in a malaria area. Do not self-treat. If you take prophylaxis and still get sick, that is rare but possible; medical care in Maun is available; serious cases are airlifted to Johannesburg.
