Infectious Disease Compendium

Molluscum contagiosum


A pox virus. Also called water warts, but spread in pools is unproven. There are 4 types of MCV, MCV-1, 3 and 4. MCV-1 is the most prevalent and MCV-2 is seen in adults and is often sexually transmitted.

Epidemiologic Risks

Found in humans all over the world and spread by contact. Very infectious.


Papules with umbilication (a little belly button), often seen on the skin of HIV patients.

In normal hosts, usually kids, it goes away in a year or so.


Liquid nitrogen or other mechanical removal; they often improve with improvement of the immune system.


It is closely related to a horse virus. Did we get it from riding horses/donkeys?
