Final answer:
A significant rabies risk is associated with a bite from all of the following except humans. Wild animals such as foxes, bats, and skunks are common reservoirs of rabies, while human-to-human transmission is extremely rare.
Step-by-step explanation:
A significant rabies risk is associated with a bite from all of the following except A. humans. The most common reservoirs for rabies in the United States are wild animals such as foxes (4.1% of all animal cases during 2014), bats (29.1%), and skunks (26.3%). These animals, along with raccoons, account for 92.6% of animal rabies cases in the US. On the other hand, the incidence of rabies being transmitted to humans from other humans is extremely rare and not considered a significant risk.
Rabies is a deadly disease caused by the rabies virus, which is a member of the Rhabdoviridae family. This virus is usually transmitted through the bite of an infected mammal. After a bite, the virus travels to the central nervous system, leading to symptoms like hydrophobia, aggression, and in severe cases, death. Human cases in the US are rare, largely due to the success of vaccination programs for domestic animals and wildlife.
