Several epidemiological determinants influence relapsing malaria:
1. Geographical Distribution: Relapsing malaria is predominantly found in regions where P. vivax and P. ovale are prevalent, including parts of Asia, Latin America, and Africa. 2. Seasonality: Transmission rates can vary seasonally, especially in regions with distinct wet and dry seasons. 3. Vector Ecology: The presence and behavior of Anopheles mosquitoes, the primary vector, play a crucial role in disease transmission. 4. Human Factors: Population movement, immunity, and access to healthcare can significantly affect the epidemiology of relapsing malaria.
