The majority (65%) of HPV viruses die within half an hour after leaving the body, and surviving viruses can survive in a warm and humid environment for about 2 hours, during which time there is a possibility of infection if others come into contact with the virus. The above-mentioned people only have this possibility, the real infection also needs many conditions, first of all, the source of infection will be discharged enough virus, that is, the viral load is sufficient, secondly, the transmission route as much as possible for a short period of time exposure to a sufficient amount of surviving virus, the site should be warm and moist mucous membrane parts such as vulva, perianal, oral cavity, and these parts have a small wound, and again is the susceptible people must also have to fight the virus The immunity is poor, and the concept of hygiene and awareness of disease prevention are not enough. Due to the specificity of the virus and the above mentioned pathogenic factors, the possibility of acromegaly infection in this way is only theoretical and no clinical cases have been reported.
