[The epidemiology of scabies]

Area of Science:

• Dermatology
• Epidemiology
• Public Health

Context:

• Scabies is a contagious skin infestation with significant public health implications.
• Understanding scabies transmission patterns in different settings is crucial for effective control.
• Previous studies have not systematically analyzed the structure of scabies morbidity in families and organized collective bodies.

Purpose:

• To review existing literature on scabies morbidity structure.
• To introduce and define the concept of a 'disease focus' in scabies.
• To analyze the characteristics of scabies foci in families and organized collective bodies based on author data.

Summary:

• A review of Soviet and foreign literature on scabies morbidity was conducted.
• Analysis of 88 clinical and epidemiological charts introduced the concept of scabies 'disease foci'.
• Potential foci (single patient) were predominantly in organized collective bodies (85.7%), while irradiating foci (multiple patients) were mainly in families (80.7%).

Impact:

• The study differentiates between potential and irradiating scabies foci.
• Findings suggest that scabies transmission intensity, not focus size, is determined by contact duration and intensity.
• This research provides a new framework for understanding and managing scabies outbreaks in community and institutional settings.
