Molluscum contagiosum
Molluscum contagiosum Causes
MC is caused by the poxvirus Molluscum contagiosum. People may get this though direct contact with people who have the disease or sharing towels and clothing.
Molluscum contagiosum Definition
A viral infection of the skin or occasionally of the mucous membranes, Molluscum contagiosum or MC has no animal reservoir and just like smallpox, only infects humans. MC has four different types namely MCV, MCV-1 to -4. The most prevalent is MCV-1, while MCV-2 commonly occurs among adults and is often sexually transmitted. The genitals, lower abdomen, buttocks and inner thighs are often affected in sexually transmitted MCV-2. The lips, mouth and eyelids may also be affected in rare cases.
Molluscum contagiosum Diagnosis
A physical examination can diagnose the condition but unclear results may bring health professionals to take a sample of the bump and conduct a biopsy. Physicians may also check for other STDs such as herpes if the bumps are found on the genital area.
Molluscum contagiosum Symptoms and Signs
Molluscum contagiosum lesions usually appear flesh-colored, dome-shaped and pearly. They also have a dimpled center and are often 1-5 millimeters in diameter, generally not painful but may itch or become irritated. The bumps are not supposed to be picked or scratched since it can lead to further infection and scarring. Eczema develops around lesions in about 10% of MC cases.
Molluscum contagiosum Treatment
MC usually resolves itself in 6-8 weeks or 2-3 months, that is the virus won't spread via autoinoculation. With autoinoculation, the disease may last up to 8 months or 18 months, with a range of durations from 6 months to five years. Treatments may however shorten the duration of the infection. Using over-the-counter products such as Betadine, astringents, wart medicines, salicylic acid and tretinoin cream. Non-medical treatments like cutting across the head of the lesion with a sterilized needle and removing the papule with an alcohol swab may heal the bumps in 2 to 3 days. Surgical and laser treatments are options.
