The secret of HPV transmission

　　HPV (human papillomavirus) is a common virus and understanding how it is transmitted is crucial to preventing infection. The following is a detailed introduction to the transmission routes of HPV.

Sexual contact transmission

　　sexually transmitted: Sexual contact is the main route of transmission of HPV. You may be infected with HPV if you have sexual intercourse, including vaginal intercourse, anal intercourse, oral intercourse, etc., with an HPV-infected sexual partner. Unprotected sex, in particular, carries a higher risk of infection.

　　Risks of multiple sex partners: Having multiple sex partners increases your chances of getting HPV. The more sexual partners you have, the greater your chance of being exposed to HPV.

mother-to-child transmission

　　mother-to-child vertical transmission: During delivery, mothers infected with HPV fetus You can become infected with HPV while passing through the birth canal. In addition, HPV in the mother during pregnancy may also be transmitted to the fetus through the placenta, but this is relatively rare.

　　childbirth transmission: When a fetus passes through the birth canal of an HPV-infected mother, it may be exposed to secretions containing the virus, which can lead to infection.

indirect contact transmission

　　indirect article communication: HPV can survive on some surfaces for a period of time. If you come into contact with items contaminated by HPV, such as towels, towels, toilets, etc. in public baths, you may be infected. For example, using contaminated bath towels in public bathrooms, or using towels that have not been thoroughly disinfected in hotels.

　　spread by hand contact: If your hands come into contact with items contaminated by HPV and then touch your own genitals and other parts, it may also lead to infection. Therefore, it is very important to keep your hands clean.

Iatrogenic transmission

　　Medical device dissemination: In medical operations, if medical equipment contaminated with HPV and not strictly sterilized is used, the virus may be transmitted to other patients. For example, some Gynecology Check equipment, etc.

　　Transmission by medical staff: If medical staff do not take protective and disinfection measures after contacting patients infected with HPV, and then contact other patients, it may also cause iatrogenic transmission.

skin Transmission by mucous membrane contact

　　tiny breaks in skin: When the skin is slightly damaged and comes into contact with substances containing HPV, the virus may enter the body through the damage and cause infection. For example, in places such as public swimming pools, the risk of infection increases if there are wounds on the skin.

　　spread by close contact: Close physical contact with someone infected with HPV, such as long-term hugging, kissing, etc., may also spread HPV through skin and mucous membrane contact, but this mode of transmission is relatively rare.

　　HPV is a double-stranded circular DNA virus with multiple subtypes. Persistent infection with some high-risk HPV types may cause cervical cancer malignant tumors, low-risk HPV may cause genital warts and other benign sexually transmitted diseases Change.
