We are scheduled to visit Victoria Falls(Zimbabwe), Cape Town, Hazyview and Kruger( Ngala Lodge) end March early April. As we live in Sri Lanka most of the year , I am wondering if Malaria prevention is an absolute must. We have never used Malarone?? before and not too keen on taking it. I know it is our personal choice but wondered if we could just use repellants and suitable clothing to avoid getting stung.
