We are thinking of travelling to Malawi in August. Our son went there last year to source some coffee for his business. He was so impressed he plans to return for a holiday with his wife and two young children in August. He would like us to join them for a few days in the Thylo region at Satemwa on the plantation and a few days by the lake using private hire cars. Having read the Bradt guide however, I am really worried about health issues, malaria,bilharzia, dengue, stomach ailments etc. and crime out there. We will be travelling with our son who has special needs, he is 28 but very slight, short build and can only eat pureed meals. We have been with him to Cuba, Australia, South Africa without any problems but as my other son says Malawi is "raw Africa". We would love to go and would appreciate any advice. We are keen travellers.
