Welcome to the Forum. You are correct, viruses and, for that matter, bacteria can pass through clothing that has been wet with genital secretions. Despite that however, the are no instances in which STDs, including HPV have been shown to be transmitted in this way. There are a number of reasons which contribute to this. These include that microorganisms have a tendency to stick to material fibers when they come in contact, that the exposure to the environment damages the organisms and that the biology of transmission of HPV and other STDs seems to depend upon DIRECT contact between infected and un-infected epithelial surfaces for transmission to occur. Neither of us working on this Forum have ever seen HPV or HSV transmitted through clothing. Perhaps it is theoretically possible but it is certainly not something to worry about. EWH
Thank you for your good answer.Can I think another reason that the number of virus required for infection,In this case,most of them can't pass through clothing?
You are correct, the more viruses that are present, the more likely infection is to occur. EWH
Thank you, I appreciate you.
