A Study of the Concentration of Yellow Fever Virus which Will Infect Certain Species of Aedes Mosquitoes
Summary
- 1. A study was made of the concentration of virus which was necessary to infect certain species of Aedes mosquitoes with yellow fever.
- 2. The lowest titer at which transmission by bite occurred was 10-3.0.
- 3. Half or more than half of the mosquitoes, which fed on primates circulating yellow fever virus at titers of 10-5.0 or above, became infected after extrinsic incubation periods of at least 28 days at 28°C.
