I am a huge advocate. Phil (my partner, who has lived in the Zambian bush all his life) has had malaria somewhere between 40 and 50 times in the past. We are coming into our 5th year with no incidence whatseover, being very attentively on Demal 200 (careful not to miss a single dose in addition to taking normal preventative measures). For him this is an almost unbelievable record! It is proof enough for us, after a lifetime for him of haphazard prophylaxis; wretched chemical cures, and nasty side effects…chloroquine, Halfan, fansidar, quinine etc etc). We can only attribute this welcome outcome to Demal 200!
