Carter was a quarantine officer and a field epidemiologist, best known for his discovery in 1898 of the extrinsic incubation period of yellow fever.
He never considered the possibility of an extrinsic incubation period that would require time for the agent of yellow fever to incubate within mosquitoes.
Such predictions often refer to vectorial capacity, a simple model that incorporates the population density, biting frequency, and daily survival probability of the vector, and the extrinsic incubation period of the pathogen (15,16).
