Wilbur A. Sawyer on horseback in Banco Vitoria near Ilheus, Brazil
In 1934, 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. Several weeks later they investigated similar reports in the eastern state of Bahia. In this photo Dr. Sawyer (foreground) and Dr. Machado set out to visit the parents of a victim.
