1. What causes plantar warts
Just like any other type of warts, plantar warts are also caused by a virus –the human papillomavirus (HPV types 1, 2, 4, 57, 60, 63, 65, or 66. In case you don’t know, there are over 100 different types of HPV viruses). It enters the human system through small cuts or other kinds of foot lesions, even if they are very superficial. So yes, that means that plantar warts are contagious. However, the virus that causes this medical issue is not easily transmitted by direct contact from person to person. Instead, it can be often present in warm and moist environments such as locker rooms and public swimming pools. That is why you should always wear flip flops on communal showers.
There are several factors that make children and teenagers more vulnerable to develop plantar warts. For starters, they use communal showers much more frequently than the average adult because they play sports at school and engage in group activities more often. On the other hand, the majority of adults develop immunity to this virus throughout their lives.
People with a weak immune system such as HIV patients and those who are taking immunosuppressive medications are also at greater risk of being infected by the HPV virus.
