The molluscum virus is usually transmitted by direct skin-to-skin contact (e.g., contact sports [karate] sexual activity, horse play and even mild contact). Someone may become infected by contaminated objects (fomites) such a towels, soft toys, shaving equipment, tattoo equipment, electrolysis tools, sponges, bathing scrubs, bed sheets and clothing. The virus can traverse from one part of the body to another (auto-inoculation or self-reinfection) simply by touching a lesion then touching another area of one´s own skin.
Exposed and broken lesions have a greater capacity to transmit the virus. The presence of lesions enhances the possibility of transmitting the infection to another person. When the lesions are gone, so is the possibility for spreading the infection.
