Malaria is only a concern in the Kruger Park area. Outside of that Limpopo is malaria free. Because of my age and other health issues, I did take a low grade antibiotic for three days prior to leaving and thirty days thereafter. It is one of the approved "protocols" for malaria but a heck of a lot cheaper than the stuff most often recommended. Besides that you will be hunting in the dead of their winter. Not many mosquitos around. If you have a smartphone get the app for Weather Underground. Set Ellisras South Africa as a location and you will get the up to date weather for the ranch. Do not over pack, Wear one set of hunting clothes on the plane and take two sets with you. It can be quite chilly in the A.M. so consider taking two sets of "base" layer long johns. Take a lightweight water proof jacket a zippered camo hoodie if you can find one and a pair of wool gloves. My wife is a Texan we have a lot of friends and relatives that live there, where are you from? I've hunted hogs in the San Antonio area several times. Had a blast.
