We're visitng Botswana for the first time over he Christmas/New Year period - can't wait to go already. But would like advice re malaria precautions as one health site I've visited suggests you only need take precautions north of the Kalahari. We start out trip by arriving in Maun & then go straight that day to the Central Kalahari reserve - after that we go to the Delta. So does this mean that we needn't start the pills till we're heading back north to the Delta camp. Can anybody help on this one?
