Molluscum contagiosum viruses refer to a group of DNA viruses that cause a benign skin infection known as molluscum contagiosum. These viruses belong to the poxvirus family and primarily infect humans, though rare cases of animal infection have also been reported. Molluscum contagiosum viruses are highly contagious and can be easily transmitted through direct contact with an infected individual or by touching contaminated objects.
The infection caused by these viruses manifests as small, flesh-colored or pinkish bumps on the skin, usually with a characteristic central indentation. These bumps, medically referred to as mollusca, are usually painless but may become itchy or irritated. Molluscum contagiosum viruses typically affect areas of the body with thin skin, such as the face, neck, armpits, and genital region. The incubation period for the virus ranges from two weeks to six months.
The immune response of the infected individual usually results in the spontaneous resolution of the infection within six months to two years. However, in immunocompromised individuals or those with atopic dermatitis, the infection may be more persistent and widespread.
Treatment options for molluscum contagiosum viruses include physical methods such as cryotherapy or curettage, and topical antiviral medications. However, treatment may not always be necessary, especially in cases where the mollusca are not causing discomfort or spreading. Proper hygiene practices, including avoiding sharing personal items and frequent handwashing, can help prevent the transmission of molluscum contagiosum viruses.
