2-3 wks, but rare. Rabies has an incubation period (time from exposure to symptoms) of 2-3 weeks, but is very rare in north america. Most rabies on this continent is found in wild rodents & animals such as squirrels, prairie dogs, bats and even raccoons. If a person gets bit by a dog which doesn't have proof of rabies vaccination, the local animal control department can often quarantine the dog for observation.
