Are there any confirmed cases of genital hpv (warts) being transferred via fomites? eg non-sexually. i get a lot of anxiety about accidentally transmitting the virus to a friend or family member?

There always have been such fears, and some people with genital warts claim that's how they caught HPV. However, there has never been a proved case that it actually happens. Household contacts of infected people never get HIV, even after years of sharing toilets, towels, and even clothing. Warts can appear years after being infected, contributing to misunderstanding of how they were infected.
