First definite proof that the organism causing yellow fever is transmitted to man by the mosquito Aëdes aegypti. During the period spent by these workers in the investigation of the disease in Cuba Lazear and Carroll subjected themselves to the bite of infectious mosquitoes to test the theory that mosquitos were carriers of yellow fever. Lazear died from the yellow fever infection in 1900, but Carroll recovered and completed the research. He later died of the yellow fever infection in 1907.
