Is molluscum contagiosum contagious?
With part of its name being contagiosum, you can be sure it is contagious. The virus is transmitted by skin-to-skin contact and by indirect contact (for example, towels touched by an infected person may allow the virus to pass from the towel to another person's skin.
What is the incubation period for molluscum contagiosum?
The average time from exposure to symptoms (incubation period) is about two to seven weeks and may be as long as six months in some individuals.
How long does the infection with molluscum contagiosum last? When does a person become noncontagious?
The skin lesions last about six to 12 months although some individuals have had lesions last up to four years. Once the lesions spontaneously resolve, the person is not contagious; the contagious period is quite variable and depends on when the lesions resolve.
What causes molluscum contagiosum?
The cause is a virus, molluscum contagiosum virus, a member of the poxvirus family. The virus only survives in the skin, and when the lesions are gone, the person no longer is contagious.
What are risk factors for molluscum contagiosum?
The highest risk factor is when an uninfected person touches a skin lesion on an infected person's skin or contacts an item such as a towel that was recently used by an infected person. People with weakened immune systems are at risk for getting the infection and having it rapidly spread with larger lesions. Other people at high risk are wrestlers, swimmers, gymnasts, and people who use steam baths and saunas. It's also possible to transmit the infection sexually. It is theoretically possible to become in contact and be infected with the virus from a toilet seat, but this has not been documented.
