Transmission electron micrograph of plantar wart virus, the cause of plantar warts or verrucae in humans and a member of the Human Papillomavirus (HPV) group. The virus particles's icosohedral protein capsids are clearly visible in this image. HPV infections are transmitted by direct contact. In the case of plantar warts, which occur on the soles of the feet, virus particles have been found on contaminated bathroom floors and towels, in communal showers and around swimming pools. Plantar warts (along with common and flat warts) are most common in children; the lower incidence in adults may be an acquired immunity. Magnification: x170,000 at 11x17cm size.
