Major tropical disease mechanisms were identified within one decade

Evidence

In 1894 the plague bacillus was isolated; in 1897-1898 the transmission of malaria by the Anopheles mosquito was worked out; in 1901 the vector for yellow fever, the Aedes aegypti mosquito, was definitively identified; and in 1901-1903 the trypanosome responsible for sleeping sickness was isolated. Through these victories, the germ theory of disease was further vindicated and the new discipline of tropical medicine was born. — Alice L. Conklin, A Mission to Civilize_ The Republican…, 211
