Animal Bites and Bat Encounters
Spring and summer months tend to be busy in public health for calls regarding animal bites and bat encounters. In 2015, 13 animals from Washtenaw County have already been submitted to the State Lab for rabies testing. Fortunately, none of the tests have been positive to date.
When the possibility of rabies is being considered, animal bites and bat exposures must be reported to Washtenaw County Public Health within 24 hours of the bite/exposure incident. Public Health will determine whether testing or quarantine of the animal is recommended (if the animal is available). Rabies risk assessment requires balancing a number of criteria:
- the species of animal and the prevalence of rabies for that species in Michigan
- the observed health and behavior of the animal
- the vaccination history of domestic/farm animals
- and the circumstances of the bite (provoked vs. unprovoked)
