The most potent risk factor for the development of rabies is a bite from an infected animal. People that live in an area, or travel to an area that has a large incidence for rabies, are at a high risk for acquiring rabies from a rabid animal. Handling certain wild animals such as bats or raccoons will put a person at a higher risk.
