Though not very common, technically, Hwange is in a malarial zone. We recommend having medication with you, but would urge you to look into the latest World Health Organisation recommendations, as some countries in which malaria is not common still advise out-of-date treatments. At the pharmacy in Victoria Falls or Bulawayo, you will find a ready supply of Coartem, to be taken upon displaying symptoms, which usually show up within two weeks of being bitten.
