Malaria in Dar es Salaam

Recently a number of cases of malaria have been diagnosed in travellers returning from Dar es Salaam in Tanzania. Some of those with it were air crew who had only stayed one or two nights in the city during May. The heavy rains in this area may have contributed to the increased risk of malaria transmission. It is really important to remember that in Africa many cities have a risk of malaria and that night time mosquito bite avoidance and prophylacitic medication is needed.  Many Asian cities have low risk of malaria but that is not true in Africa.
