Risk is absent in most of the country; risk exists only in specified areas:
Risk is present in the rural and urban areas of Ngamiland District (sub-districts of Okavango, Ngamiland East and West), Chobe District (including Chobe National Park), Central District (sub-districts of Bobirwa, Boteti, Mahalapye, Serowe/Palapye, and Tuteme), North-East District, and Ghanzi District (northern half). Use malaria suppressive medication for these areas (see below). For the rest of the country, take meticulous anti-mosquito bite measures.
Note: Gabarone is risk free.
High risk months for Malaria are: November to June
Malaria transmission vector(s): A.gambiae
Incidence of Plasmodium falciparum Malaria: >90%
Of the five species of human malaria parasites, Plasmodium falciparum is the most dangerous. The remaining percentage represents malaria infections that may be caused by one or more of the following parasites: Plasmodium vivax, Plasmodium ovale, Plasmodium malariae, and Plasmodium knowlesi.
Areas with drug resistant Malaria: P. falciparum malaria is resistant to chloroquine. Resistance is present in all malarious areas of Botswana.
All malaria infections are serious illnesses and must be treated as a medical emergency. In offering guidance on the choice of antimalarial drugs, the main concern is to provide protection against Plasmodium falciparum malaria, the most dangerous and often fatal form of the illness.
Regardless of the medication which has been taken, it is of utmost importance for travellers and their physician to consider fever and flu-like symptoms appearing 7 days up to several months after leaving a malarious area as a malaria breakthrough. Early diagnosis is essential for successful treatment.
In addition to the suggested antimalarial medication, use a mosquito bed net and effective repellents to avoid the bite of the nocturnal Anopheles mosquito.
