Observations on the Recession of Malaria in an Area of Southwestern Georgia

View More View Less


Observations were made to detect malaria occurrence from April 1939 through 1948, in an area where the disease occurred formerly at a high rate. Transmission of vivax was negligible during the period of the study. A single epidemic of falciparum was apparently responsible for a majority of infections encountered. Treatment of positive cases with quinacrine hydrochloride may have been responsible for the rapid termination and limited extent of the epidemic.

Factors which prevent the recurrence of malaria in the study area are obscure. It is believed that improvement of economic conditions has enabled the population to apply, intentionally and indirectly, individual control, prophylactic, and curative measures.
