Final answer:
Squirrels are the least common transmitters of rabies in Canada and the United States, with the more common reservoirs being raccoons, bats, skunks, and foxes. Rabies is spread through the bite of an infected mammal, but control measures like vaccinations for pets and wildlife have greatly reduced transmission risks.
Step-by-step explanation:
The animals that are the least common transmitters of rabies in Canada and the United States are squirrels. According to data from wild animals in the United States, the most common reservoirs for rabies are raccoons, bats, skunks, and foxes. Squirrels and other small rodents are rarely infected with rabies and are not considered major factors in its transmission.Understanding Rabies Transmission Rabies is primarily transmitted through the bite of an infected mammal. Rabies vaccination programs for domestic animals such as dogs and cats, as well as wildlife oral vaccine programs, help control the spread of the disease in the United States. Although rabies is a serious and often fatal condition if left untreated, the likelihood of contracting rabies in the US is low due to these preventative measures.
