Kissing does not transmit HPV

US researchers ran DNA tests for 36 strains of HPV in saliva samples taken from 164 cancer patients and their partners. While more than half of the cancer patients had detectable HPV in their saliva, the virus only showed up in 1.2% of partners tested.

The authors said the finding suggests oral HPV is not being transmitted in the saliva when partners kiss, or they have effectively cleared the infections they’ve been exposed to.

However, they said it is not yet known if a person with oral HPV infection could transmit the virus to their partners
