molluscum & Zelsuvmi Overview

8 Molluscum Contagiosum A highly infectious viral condition primarily affecting children 1 year of age or older There are four known types of MC virus (MCV1, 2, 3, 4) with MCV1 being the most common1 Molluscum Contagiosum is caused by a pox virus and is characterized by small, round, firm, umbilicated, often painless bumps. Even after healing, re-infection is possible if in contact with an infected person or object4. ~17 million people infected in the U.S. MC can take up to five years to resolve without treatment2 Peak incidence between 1-10 years of age. Up to 73% of children go untreated3 Point prevalence of 3-6 million children (ages 0-16) in the U.S. Infection, Persistence, and Spread Visible and Psychological Impacts Pain & Skin Irritation Auto- inoculation2 Highly contagious to others ? risk of secondary bacterial infections2 Potential worsening of atopic dermatitis Itching, redness Inflammation Anxiety Social withdrawal Untreated Molluscum Contagiosum Has Severe Effects 1) Hebert AA, Bhatia N, Del Rosso JQ.
