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. Here Dr. Soper and Dr. Alexander Burke pose with Mr. Lisboa, the village telegraph operator, who had alerted the public health authorities about the yellow fever cases.
