Which animals are classified as rabies vector species?

The classification of rabies vector species includes those animals that are most likely to transmit rabies virus to humans and domestic animals. Among the options presented, skunks, raccoons, foxes, groundhogs, bats, and coyotes are all known carriers of the rabies virus.

Raccoons, in particular, are significant reservoirs of rabies in many parts of the United States, including Pennsylvania. Bats are also a primary vector for the disease, and certain species are considerably associated with rabies outbreaks. Skunks and foxes, although less prevalent in some areas compared to raccoons, are also recognized carriers. Groundhogs and coyotes can harbor the virus as well, contributing to the overall threat posed by these species in terms of rabies transmission.

The other options include various animals that either do not have a significant role in rabies transmission or are not considered vector species at all. For instance, while domestic cats and dogs can contract rabies, they are typically considered domestic species rather than wildlife vector species. Pigs, horses, and deer do not commonly transmit rabies and are not included in the list of rabies vector species. Thus, the selection of skunks, raccoons, foxes
