Title:

Letter from Wilbur A. Sawyer to Margaret Sawyer

Creator:

Sawyer, Wilbur A.

Recipient:

Sawyer, Margaret

Date:

23 June 1934

Description:

From late May to early August 1934, Dr. Sawyer again visited yellow fever control operations in Brazil. This included a ten-day trip to the Mato Grosso region to check on several puzzling outbreaks of yellow fever in rural areas, and led to the recognition (by Dr. Fred Soper and others) of a new infection pattern: jungle yellow fever. Although Sawyer and Soper were now able to travel by plane to some areas, this letter made it clear that roads and accommodations were still quite primitive in much of the region.
