Common Warts Overview
Common warts are just one of the many types of warts that can affect the human body. They are caused by a virus called the Human Papilloma Virus (HPV). There are over 100 different strains of HPV and some cause warts to develop on the skin. HPV is highly contagious and can be spread through direct skin to skin contact or through indirect contact such as on towels and pool sides. Warts affect the top layer of the epidermis (skin) and can affect any part of the body but are more commonly found on the hands, on the knuckles and on the fingers around the nails. You may have just one wart or a cluster of warts; usually, however, you won’t have more than 20 warts at any given time.
It is possible that someone who is already infected with the HPV virus and has warts can re-infect themselves on different areas of their body. Warts tend to affect children, young adults and those who suffer with immunodeficiency such as those with HIV/AIDS and people receiving treatment that compromises their immune system. Warts are not usually problematic to the sufferer and can be left to improve on their own. Occasionally the sufferer can experience a problematic wart that does not improve and needs treatment.
