Honest about the risks, and specific about what prevents each one.
Malaria — in some districts
CDC names the transmission districts for Botswana: Bobirwa, Boteti, Chobe including Chobe National Park, Ghanzi, Mahalapye, Ngamiland, North-East including Francistown, Okavango, Serowe/Palapye and Tutume. It lists rare or sporadic cases in Kgalagadi North, Kgatleng, Kweneng and Southern, and no transmission in Gaborone. Chloroquine resistance is present and P. falciparum is the main parasite, with P. malariae, P. ovale and P. vivax less common.
Prevention Where CDC lists transmission, prescription tablets — atovaquone-proguanil, doxycycline, mefloquine or tafenoquine. Where it lists only rare or sporadic cases, CDC recommends no preventive medicine and insect bite precautions instead. Either way: repellent, long sleeves at dusk and a treated net.
Being a long way from a hospital
The Government of Canada says quality of care varies greatly, that services are below Canadian standards outside Gaborone, that facilities may lack basic supplies and have inadequate or obsolete equipment for serious procedures especially in rural areas, and that you will likely need medical evacuation in the event of serious illness or injury. Private facilities may request proof of insurance or immediate payment in cash.
Prevention Travel insurance that names medical evacuation and hospital stays, bought before you go. Know whether it pays directly or reimburses. Policy number saved offline. Ask the camp what happens and how long it takes — and bring your own medicines, since some may not be available there.
Wildlife, unfenced
The Government of Canada notes that national parks may not automatically provide a guide when you enter on your own, and that wildlife areas are not always fenced with few warning signs. It also names wildlife and stray livestock on the road among the causes of frequent fatal accidents. CDC adds that rabid dogs are commonly found in Botswana and that rabies is present in some terrestrial wildlife.
Prevention Hire a guide rather than assume one. Treat the ground between your tent and the vehicle as part of the park. Do not touch or feed animals you do not know — and any bite, scratch or lick on broken skin means washing for fifteen minutes with soap and running water, then medical advice the same day.
Roads
The Government of Canada says fatal accidents are frequent in Botswana, naming driving under the influence, pedestrians, wildlife and stray livestock on the road, and mobile phone use while driving. The distances between towns are long and the animals do not read the signs.
Prevention Avoid driving after dark — that is when animals on the road are hardest to see. Take the long transfers with a driver or a charter rather than a tired self-drive. Seatbelts, including in the back.
Fresh water
Both sources warn about schistosomiasis in Botswana. The Government of Canada asks travellers to avoid contact with untreated fresh water such as lakes, rivers and ponds — swimming, bathing, wading or swallowing it. CDC describes transmission through wading, swimming, bathing or washing in contaminated fresh water including untreated pools, and names leptospirosis as another reason to avoid contaminated water and floodwater. There is no vaccine and no preventive medication for schistosomiasis, and neither source clears the Okavango or any other particular water.
Prevention Treat untreated fresh water as one category, because that is how the guidance is written. Chlorinated pools are fine. If a water activity is part of your booked itinerary, raise it with us before you go rather than deciding at the bank.
Flooding
The Government of Canada notes severe flooding, especially in the Chobe District in north-eastern Botswana, caused by high water levels in the inland Okavango Delta, which floods dry Kalahari land every year. That is a seasonal fact about the landscape rather than a disease, but it changes roads, access and how quickly anyone can reach you.
Prevention Check conditions for your dates before you commit to a driving route. CDC advises avoiding floodwater, which is also where leptospirosis appears.
Ticks and mosquitoes beyond malaria
CDC names dengue, African tick-bite fever, leptospirosis, hantavirus and tuberculosis among what travellers to Botswana may encounter. The Government of Canada names chikungunya as a risk that varies by season, year, region and elevation, and asks for mosquito bite protection at all times.
Prevention Repellent through the day, reapplied. Long trousers and closed shoes in grass and bush, with a tick check after a walking day. Permethrin-treated clothing for camping and walking safaris.
