In addition, individuals should see a health care provider immediately.

Anyone whose pet touched this bat should call Fremont Animal Services at 510-790-6630 as well as their veterinarian.

Dogs and cats not vaccinated for rabies are also considered to be at medium to high risk for carrying the virus. If an ill or dead animal is found, do not touch it. In addition, if you witness an animal which is normally nocturnal during the daylight, acting in a strange manner (i.e. a skunk roaming or staggering in the daylight, a bat hanging on a window screen or sill or a fox acting aggressive in the daytime, etc.), it should also be reported to Animal Services or the Alameda County Public Health Department.
