Created in 1997, Training Programs in Epidemiology and Public Health Interventions Network (TEPHINET) is a professional network of 69 field epidemiology training programs (FETPs) working in more than 100 countries. TEPHINET aims to strengthen international public health capacity by training field epidemiologists through an applied apprenticeship program. Trainees of FETPs master a set of core competencies that are vital to the practice of public health, while providing a valuable public health service to their countries and regions.
