QUESTION

could you please let me know, whether or not a malaria prophylaxe injection is necessary for a 3-weeks trip by car in Namibia, starting mid August.

ANSWER

It depends on where you are going in Namibia. According to the US Centers for Disease Control, malaria is transmitted in Namibia in the provinces of  Kunene, Ohangwena, Okavango, Omaheke, Omusati, Oshana, Oshikoto, and Otjozondjupa and in the Caprivi Strip. As such, if you are travelling to any of these areas, you should consider taking medication to prevent malaria. Three types of medication are considered equally effective in these regions: atovaquone-proguanil (Malarone), mefloquine (Lariam) and doxycycline. Which one you decide to take is mainly a matter of personal preference, based on details such as how often you will need to take a tablet (every day for Malarone and doxy, once a week for Lariam), how long you want to take the medication (Malarone is started the day before your trip, and should be taken for a week after, doxy is also started 1-2 days before travelling but must be taken for 4 weeks after returning and Lariam is started 2 weeks before travelling and for 4 weeks afterwards) and price (Malarone is the most expensive, and doxy usually the cheapest). In addition, each has different potential side effects (Malarone usually has the fewest; doxy can result in sun sensitivity, and Lariam may have psychiatric side effects, and is not recommended for anyone with a history of mental illness).
