Why a scratch without blood can still lead to rabies

A minor scratch or a superficial nip from an animal may seem harmless, but the absence of blood does not rule out the risk of rabies. The virus can enter the body through microscopic cracks in the skin, making immediate action critical.

The first category involves simple touch or an animal licking intact skin. In these instances, no specific medical treatment is needed beyond standard hygiene.
