Molluscum Contagiosum Management

Introduction to Molluscum Contagiosum

• Molluscum contagiosum is a viral skin infection that can spread through direct skin-to-skin contact, and maintaining good personal hygiene with regular handwashing is recommended by the American Academy of Pediatrics to prevent the spread of infection 1

Prevention and Control Measures

• Preventing the spread of molluscum contagiosum can be achieved by covering lesions, maintaining good hand hygiene, especially after touching lesions, and avoiding sharing personal items like towels and clothing 1, 2
• The American Academy of Pediatrics recommends specific guidelines for high-risk individuals, such as Food Service Workers, Athletes/Contact Sports Professionals, and Childcare Workers, including covering lesions, maintaining strict hand hygiene, and avoiding direct skin contact with others 1
• Wearing flip-flops or sandals in communal showers, showering thoroughly before and after swimming, and using personal towels only is suggested to prevent infection spread 1
• Cleaning and disinfecting shared surfaces that may come in contact with lesions, and implementing strict handwashing protocols for all individuals is recommended 1

Treatment Options for Molluscum Contagiosum

• Treatment options for lesions that require intervention include:

1, 3

• Cantharidin is a well-tolerated and effective treatment option for bothersome, extensive, or symptomatic lesions, with minimal side effects, and is applied by a healthcare provider, offering comparable efficacy to cryotherapy 2, 1

Management of Special Cases

• Lesions near the eyes require prompt treatment to prevent ocular complications like conjunctival scarring, epithelial keratitis, and pannus formation, as recommended by the Ophthalmology society 2, 4
• The American Academy of Pediatrics recommends observation for asymptomatic, limited lesions in immunocompetent patients, with consideration for special cases such as lesions near the eyes to prevent conjunctivitis and potential sequelae 2
• Local anesthesia can be considered before cryotherapy for painful lesions, and the British Association of Dermatologists recommends avoiding painful treatments in young children if possible, considering the child's ability to cooperate 3, 5

Monitoring and Follow-up

• Regular monitoring every 1-3 months to assess progression, and consider active treatment if lesions persist beyond 6-12 months or if complications develop 5
• Spontaneous resolution of uncomplicated molluscum contagiosum typically occurs in 6-12 months, although complete resolution can take up to 4 years 1
• The American Academy of Pediatrics recommends observation for spontaneous resolution for asymptomatic, limited lesions in immunocompetent patients, with monitoring for 3-6 months, as appropriate for most uncomplicated cases 1

Antibiotic Therapy for Secondary Cellulitis

• For molluscum contagiosum with secondary cellulitis, treatment should include both antibiotic therapy targeting Gram-positive bacteria (especially streptococci and Staphylococcus aureus) for the cellulitis component and appropriate management of the underlying molluscum lesions 6
• For mild cellulitis with no significant comorbidities, oral beta-lactams (in areas where CA-MRSA is not prevalent) are recommended 6
• For more severe infections, parenteral antibiotics are the first choice, and if MRSA is suspected, glycopeptides or newer antimicrobials are recommended 6
