Which vector is primarily responsible for transmitting rabies in the U.S.?

The primary vector responsible for transmitting rabies in the U.S. is bats. Bats are significant in the epidemiology of rabies due to their ability to carry the virus without showing symptoms. They are prevalent across the country and live in diverse environments, which increases their interaction with humans and domestic animals.

The mode of transmission occurs primarily through bites or scratches from an infected bat, which can introduce the rabies virus into the host's bloodstream. As the virus affects the nervous system, it can be fatal if not treated promptly after exposure. While other animals like raccoons, coyotes, and skunks can also carry and transmit rabies, bats account for a substantial number of rabies cases reported each year, making them a key focus for public health efforts aimed at preventing rabies transmission.
