Answer

Molluscum contagiosum is a common infection throughout the United States and accounts for approximately 1% of all skin disorders diagnosed. Data reported from 1969-1983 by the National Disease and Therapeutic Index Survey show an increasing number of patient visits. The prevalence rate in patients with HIV is reported to be 5-18%, and, if the CD4 cell counts are less than 100 cells/μL, the prevalence of molluscum contagiosum is reported to be as high as 33%.
