Yellow Fever Commission

In 1900, Surgeon-General George M. Sternberg formed a commission to fight against the cause and spread of the deadly yellow fever disease. Dr. Walter Reed was appointed officer-in-charge. Reed had previously investigated malaria and typhoid outbreaks. At the time, many scientists including Sternberg believed that yellow fever spread by direct contact with an infected person or with infected objects like clothing, However, the culprit was found by the commission's research to be a mosquito-borne agent, that it was sub-microscopic, and too small to isolate. Yellow fever is now known to be caused by a virus.
