You are advised to contact your doctor or clinic around 4-8 weeks before your trip to check whether you need any vaccinations and to get their professional medical advice regarding travel to South Africa.
To help avoid heatstroke, drink plenty of bottled water/fluids, and keep out of the midday sun.
Tap water is purified and safe to drink in major cities and towns, however, we do advise that you do not drink the water in more remote places such as the camps in the National Parks - the water may be safe to drink, but it simply is not worth the risk, as bottled water is widely available.
Whatever you do, do not drink water from any river lake without firstly purifying the water. Always take water with you when you go on a hike, and have a bottle in the car on a long journey to avoid dehydration.
There is a risk of malaria in and around the Kruger National Park/Mpumalanga Province, the Limpopo (Northern) Province, and the north-eastern part of KwaZulu-Natal - check with your doctor about suitable antimalarial tablets. Try to avoid mosquito bites wherever possible - wear loose long-sleeved clothing and trousers, and use a repellent on clothing and exposed skin.
There is no risk of yellow fever in South Africa, so a yellow fever vaccination is NOT required for travellers whose sole destination is South Africa. However, in accordance with International Health Reguations, South Africa requires all travellers over one year of age arriving from a yellow fever risk country, or having been in transit longer than 12 hours at the airport of such a country, to have a yellow fever certificate. These countries include Kenya and Uganda but it is up to the traveller to check the full list here https://nathnacyfzone.org.uk/factsheet/60/yellow-fever-maps
