Rabies virus may infect a variety of hosts. The virus is most often transmitted to humans by infected dogs, but foxes, raccoons, skunks, and bats may all carry the virus. Rabies virus causes neurological symptoms including aggression, which may lead to biting and transmission via saliva. Once symptoms occur in a human, the infection is fatal. Rabies infection is thought to occur worldwide; however, the vast majority of deaths take place in Latin America, Asia, and Africa.

The white line represents 100 nanometers (nm). For comparison, the width of a human hair is about 75,000 nm, so it would be 750 times as long!
