Walter Reed (1851-1902) was appointed head of an army Yellow Fever Board to investigate the causes of an outbreak of the Disease among United States forces in Cuba. He was accompanied by James Carroll (1854-1907), Jesse W. Lazear (1866-1900), and Aristides Agramonte y Simoni (1868-1931). Aided by work done from as early as 1881 by Carlos Finlay (1833-1915), the Board concluded that yellow fever was spread by a mosquito of the genus Aedes. The discovery was reported in "The Etiology of Yellow Fever, A Preliminary Note," Philadelphia Medical Journal 6 (October 27, 1900): 790-796. In 1901, Reed established that the Disease was caused by a filterable virus, the first such human Disease shown to be caused by such an agent. Their studies of the course of the infection helped to lead to its control. Lazear died as a result of his involvement in the study. [0754] |
