Is HPV Contagious?


Yes, HPV is contagious and more than 40 HPV types can be transmitted through sexual contact with an infected person. These 40 HPV types are found in the mucosal membranes of the body and transmitted through vaginal, oral or anal sex.1 Most of these HPV infections are asymptomatic and result in no clinical disease.2 Per the CDC, “More than 90% of new HPV infections, including those caused by high-risk HPV types, clear or become undetectable within 2 years, and clearance usually occurs in the first 6 months after infection.”3 In very rare cases, genital HPV types can be spread from mother to infant.4

Most HPV types - 75 percent - are skin (cutaneous) infections and are spread by skin-to-skin contact and are not sexually transmitted.5 Cutaneous HPV types can be found on the arms, hands, feet and legs6 and are associated with common warts.7

The CDC acknowledges that there are gaps in scientific knowledge about how, why and when HPVs are transmissible as noted below:

“HPV is presumably communicable during the acute infection and during persistent infection. This issue is difficult to study because of the inability to culture the virus. Communicability can presumed to be high because of the large number of new infections estimated to occur each year.”8
