Nosocomial outbreak of scabies

Area of Science:

• Infectious Disease Epidemiology
• Dermatology
• Hospital Infection Control

Background:

• Scabies outbreaks have been sporadically reported in Michigan for a year prior to the event.
• A community teaching hospital with 558 beds experienced a significant nosocomial outbreak.

Observation:

• The outbreak occurred during the last quarter of 1976.
• The epidemic transmission involved a single patient index case.
• The spread extended to 38 hospital employees and their close contacts.

Findings:

• The transmission pathway was identified through a comprehensive review of historical records.
• Clinical data provided evidence of scabies transmission.
• Microscopic skin preparation analysis confirmed the presence of Sarcoptes scabiei.

Implications:

• Highlights the importance of robust infection control measures in healthcare settings.
• Underscores the potential for rapid community spread from a hospital source.
• Emphasizes the need for prompt identification and management of scabies to prevent nosocomial transmission.
