KwaZulu-Natal is virtually malaria-free, but we cannot say that it's entirely malaria-free. There are still some spots where there is a low risk of contracting malaria (mainly during the wetter, rainy months). Cases are usually more north, closer to the Mozambique border, where there is a higher risk of malaria.
If you come prepared, you could easily avoid infection. We always recommend that you reach out to your doctor about malaria prevention before travelling to a malaria area, as we are not doctors. Therefore, this information should not replace that issued by your doctor.
The area you will be travelling to might be a low-risk malaria area, though we still recommend you take precautions. Malaria medications are not what they used to be, and there are many new advancements as far as prophylactics go. Malanil and Malarone are great options, but again discuss your options with your doctor. If you go to your local doctor or travel clinic and ask for one of these, they are freely available in most places.
They are a one-a-day tablet, and you start taking them a day before you enter the infected area, daily while you are there, and then for seven days afterwards. It is as easy as popping a daily vitamin pill. There are zero side effects for most people, and it will not prevent you from enjoying your trip. It is always best to consult your doctor, as you may have underlying conditions which would affect which medications you will need for this trip.
