Malaria and blackwater fever in the European races of Southern Rhodesia 1897-1948
Blair, D. M.
1. Past experience shows that the improvement in the malaria and blackwater fever situation has been due to the general progress of civilisation rather than to any organised attempts to combat these diseases.2. Case mortality rates in hospital patients have not shown much improvement throughout the years.3. The virtual disappearance of blackwater fever has coincided with the introduction of the synthetic anti- malarials into general use. Blackwater fever had however been waning steadily before that time.4. A high infant mortality rate from malaria is a blot on the otherwise steady improvement in this vital statistical index.5. It would be unwise to assume that development of the low veld will proceed smoothly if the present policy continues. The past history of the Fort Victoria district gives a clearer indication as to what may be expected.6. If the mosquito vector balance is not upset there is hope that Anopheles gambiae, an anthropophilic house- haunting mosquito will be a ready victim to attack by residual insecticides.7. The social organisation of the African population living in European areas has a very important bearing on the probability of infection and this factor has not received sufficient consideration in the past.
