This image depicted Pakistani Field Epidemiology Training Program (FETP) resident advisor, Dr. Rana Jawad Asghar, as he was talking with children in the capital of the Pakistani Province of Lahore, during a polio-related field study. In this study FETP residents evaluated more than 7,000 children, in just two-and-one-half days, in 2012. Note that Dr. Asghar was wearing his Centers for Disease Control and Prevention (CDC) cap, sporting the organization’s familiar logo. The FETP trains workers on the ground to help countries build sustainable capacity for detecting and responding to health threats. The program develops in-country expertise so that disease outbreaks can be detected locally and prevented from spreading.
