Risk is present in the country; areas of risk are specified:
High risk is present throughout the year in the northern part of the country bordering Angola, Zambia and Botswana in the following regions: Kunene (including Etosha National park), Kavango West, Kavango East, and areas along the Zambezi river (Camprivi Strip). Risk is present during the rainy season (November to June) in the regions of Ohangwena, Omusati, Oshana, and Oshikoto. Follow suppressive medication guidelines in these areas (see below).
Sporadic cases are reported in Omaheke and Otjozondjupa during the rainy season. Take meticulous anti-mosquito bite measures from dusk to dawn when travelling during the risk season in these areas.
Note: Travellers visiting Etosha National Park. Khaudum Game Reserve, and the Skeleton Coast must follow a suppressive medication regimen during the risk season (see below).
High risk months for Malaria are: November to June
Malaria transmission vector(s): A.funestus, 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: Multidrug resistant P. falciparum malaria is present in all malarious areas of Namibia. The antimalarial medications listed below are effective for this country.
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.
