Numéro d’image : 11830750
| Walter Reed. Portrait of Walter Reed (1851-1902),an American physician who specialised in the study of epidemic diseases. Reed pioneered ways of preventing and controlling typhoid epidemics. In 1896 he proved that malaria was not caused by bad water. In 1899 he proved that Bacillus icteroides caused hog cholera,but not yellow fever. In 1900 Reed was appointed to investigate yellow fever in Cuba. Reed used human volunteers in disease- transmission experiments as yellow fever did not affect animals. He showed that yellow fever was not spread by touch or by contaminated bedding but by Aedes aegypti,a mosquito. Reed and J. Caroll identified the pathogen which caused the disease | |
