Which group of animals can carry the rabies virus?

The correct response is rooted in understanding the primary vectors for the rabies virus. Wild animals such as raccoons, foxes, and bats are known carriers of rabies, making them significant in the transmission of this zoonotic disease. These species are natural reservoirs for the virus, capable of becoming infected and shedding rabies to other animals and humans via bites or scratches.

Raccoons and foxes are often found in urban and suburban areas, increasing the likelihood of encounters with humans and domestic animals, while bats are known for their wide distribution and ability to roost in various locations, which can lead to unexpected contact with people.

In contrast, domestic livestock and large game animals do not typically play a significant role in the transmission of rabies. Domestic pets can indeed contract rabies, but their infection usually arises from exposure to wild animals that carry the virus rather than them being primary carriers themselves. Therefore, the correct answer highlights the wildlife that poses the most significant rabies risk in Pennsylvania.
