Abstract
Modifications observed in general and infant mortality rates were correlated with the dynamic changes in transmission induced by malaria control measures [fenitrothion spraying directed against the vectors Anopheles gambiae and A. funestus]. The observations indicated relationships between the efficacy of control and a decrease in mortality. The daily parasitological inoculation rate was reduced from 0.00958 infective bites/individual before treatment to 0.00037 after treatment (a decrease of 96%). In 2 yr, general mortality decreased from 23.9 to 13.5 deaths/1000 population and infant mortality decreased from 157 to 93/1000 live births. This indirect benefit of malaria control deserves attention in a wider assessment of measures directed against vector-borne diseases.
