Rabies
Although the possibility is remote, the biting animal may be infected with the rabies virus. Domestic animals involved in bite incidents must be observed for 10 days to ensure that they do not have rabies. Wild animals (for example bats, raccoons or skunks) may also be infected with the rabies virus, so it is important to contact a medical provider and proper authorities immediately after being bitten by a wild animal.
If the domestic animal can't be observed for 10 days, or if the bite was from a wild animal not available for laboratory analysis, a vaccine for humans is available to safeguard the bitten person from developing rabies infection. If the shots are not given, and the biting animal was suffering from rabies, there is a high probability that the person bitten will contract rabies.
Rabies infections that develop in humans are almost always fatal. Therefore, it is urgent that bites be promptly reported so that medical guidance can be immediately given.
