Publication: Produced: 18 June 1934 Language(s): No linguistic content Format: Still image Subject(s): Yellow Fever Brazil Genre(s): Archival Materials Photographic prints Abstract: Dr. Sawyer made another trip to Brazil to inspect yellow fever control activities, including an investigation of a puzzling outbreak of the disease in a rural region near the Bolivian border. With Dr. Fred Soper, Sawyer traveled by car to Coronel Ponce, where the most recent yellow fever cases had occurred. Unlike more typical yellow fever outbreaks, these had occurred in rural rather than urban areas, and the victims had been infected by non-Aedes aegypti mosquitoes at some distance from their dwellings. In this photo, Sawyer was following Soper and Dr. Burke to the field where Eulalia de Lara (who died from yellow fever the day before) had worked.
