This photograph depicted Pakistani Field Epidemiology Training Program (FETP) resident, Dr. Rehmat Ullah (seated), as he was conducting an outbreak investigation of viral hepatitis, in the Drosh region of Pakistan on August 20, 2013. After authorities reported a cluster of acute jaundice syndrome cases, in a small village near Drosh, FETP residents were called upon to investigate the outbreak, and implement control measures. Following the investigation, health officials conducted health education sessions on safe drinking water, and sanitation in the community, in order to prevent the spread of viral hepatitis. 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.
