Evans' Contribution
This disease was more common than thought and happened around the globe. Brucellosis was common among people exposed to raw milk. Evans developed chronic brucellosis as a result of her research.
Because of Evans vaccination of cows and pasteurization of milk are now routine. She is also responsible for the dramatic decline in both bovine (cattle) and human diseases.
