Scientists believe that yellow fever evolved in Africa around 3,000 years ago. Until the mid-1800s, scientists believed that yellow fever was spread by direct contact with infected people or contaminated objects. It wasn't until the 1900s that Reed Yellow Fever discovered that yellow fever was transmitted by the Aedes aegypti mosquito.
