Common warts (verrucae) on the heel of the foot. Warts are caused by infection with the Human Papillomaviruses (HPV). Common warts are most common in children; the lower incidence in adults may be due to some acquired immunity factor. Genital warts are common among those who are sexually active,and are classed as a sexually- transmitted disease. HPV infections are transmitted by direct contact. Virus particles have been found on bathroom floors,swimming pools & towels. Inoculation during sexual intercourse,via passage through an infected vagina,or orally through chewing,is known to occur | |
