HPV is a sturdy and persistent virus
Of the HPV causing wart infections, there are today a total of about 200 known types. The virus is adapted to the body parts it attacks. About 40 types of the viruses attack mucous membranes on the genitals and surrounding areas. Of these HPV 16 and HPV 18 are known to cause 70% of the cancer cases developing into cervical cancer. HPV 11 and HPV 6 cause the venereal disease condyloma. The virus exists in many variations and most of them cause warts on hands and feet.
HPV

A virus that survives outside the skin for a long period
Certain types of HPV that attack the sole of the foot, known as plantar warts, are believed to be able to survive for days and maybe even weeks on a shower floor with the right conditions. This is assumed to be an exception, but it is clear that the virus is very durable and can survive on toilet seats and towels long enough to infect further. Everyone who has attempted to get rid of a wart infection with a wart medication knows that the wart is not easily defeated even with strong chemicals applied directly on the structure of the wart. Fortunately, the body fights the HPV infection efficiently, and the infection is mostly defeated by the immune system within months up to several years in some cases.
