There is some risk of malaria in Botswana, though it’s not common for visitors to become infected. The northern half of the country has the highest risk. This includes the Okavango Delta, especially between November and June. You should follow your doctor’s advice on whether you’ll need to take antimalarials. We also recommend using high-DEET-concentration repellents, covering up with loose clothing, and sleeping under a mosquito net, which many camps provide.
