How is oral HPV infection transmitted?

Hello,

Welcome to icliniq.com.

Thanks for your query.

There is a possibility of transmitting Human papillomavirus (HPV) from oral to oral from one person to another, provided the suspected person has HPV and also if she or he has not been vaccinated against HPV.

Worldwide, the best-known route of HPV transmission is sexual transmission, which principally causes a high incidence of HPV. But this myth has been busted in recent times.

HPVs have also been diagnosed in children and adolescents who are not sexually exposed, so other means of transmission are considered.

The virus can be transmitted from the mother to the embryo, fetus, or child during pregnancy or delivery.

HPV-related warts have also been found in people who have never had sexual intercourse; therefore, several routes of horizontal HPV transmission, such as autoinoculation, hetero-inoculation, or via fomites, are very much possible.

The best way to prevent HPV infection is primary prevention. There are secondary and tertiary preventions in diseased patients, as well.

According to recommendations from the CDC (Centers for Disease Control and Prevention) and ACIP (Advisory Committee on Immunization Practices), two or three doses of 9vHPV are recommended for both males and females ages 9 to 45 years.

HPV vaccination showed high efficacy against oral HPV 16/18 infections, and a significant proportion of participants developed long-term anti- HPV (immunoglobulin- G) antibodies in their oral fluid after vaccination.

Hope it helps.

Thanks and regards.
