Principles of Parasite Epidemiology and Control

This advanced topic integrates concepts from parasitology, epidemiology, and public health to examine the distribution, determinants, and control of parasitic diseases. Designed for final-year diploma and degree students in Zambian universities specializing in biomedical sciences, public health, or tropical medicine, the module covers key epidemiological measures (prevalence, incidence), transmission dynamics, and the focal nature of many parasitic infections. Students will analyze the social, economic, and environmental determinants of parasite transmission in the Zambian context, including poverty, water and sanitation access, and climate. The curriculum reviews integrated control strategies: vector control (insecticide-treated nets, indoor residual spraying, snail control), mass drug administration (MDA), health education, and environmental management. Case studies on malaria, schistosomiasis, and soil-transmitted helminths in sub-Saharan Africa are used to illustrate principles. Success in this topic demonstrates an ability to move from laboratory diagnosis to population-level intervention, a critical skill for careers in research, policy-making, and disease control programs within Zambia and international health agencies.
