Rabies Transmission: Kissing Does Not Spread the Virus

Rabies virus is transmitted through the saliva of an infected animal only when introduced through a break in the skin (bite, scratch, or open wound contact). Kissing does not transmit rabies because intact oral mucosa is an effective barrier, and the virus cannot penetrate unbroken skin. However, if the infected person has oral lesions and saliva contacts broken skin/mucous membranes, theoretical risk exists—but no documented cases. Standard exposure is animal bite.
