How is EEEV transmitted from horse to person?

Transmission to people requires another mosquito species to create a “bridge” between infected birds and uninfected mammals, such as people or horses. Most of the bridge species are within the Aedes, Coquillettidia, and Culex genera. Horses are susceptible to EEEV infection and many cases are fatal.
