Background: Scabies is a highly contagious skin disease caused by scabies mite infestation, resulting in intense itching. In 2023, the Korean Dermatological Association is actively implementing the "Eradication of Scabies, National Health Project" as a key initiative. Under this project, educational programs for sanatoriums and other group residential facilities, as well as nationwide public awareness campaigns, are being conducted. An expert committee of dermatologists has developed standardized clinical guidelines for the diagnosis and treatment of scabies. Current Concepts: The clinical presentation of scabies varies depending on the age and health status of the patient, the number of scabies mites, and the mode of transmission. Characteristic skin symptoms include intense itching that worsens at night and the presence of burrows and red, inflamed papules on typical areas such as finger webs, inner wrists, scrotum, and around the umbilicus. In older adults or immunocompromised infants, scabies may involve the scalp, face, palms, and soles. Atypical skin findings such as excessive hyperkeratosis, nodules, and other unusual manifestations may also occur. Discussion and Conclusion: Using the scabies diagnostic and treatment algorithm, healthcare professionals in Korean clinical settings can make rapid medical decisions when examining patients with scabies. This algorithm provides a systematic and straightforward approach to diagnosing and treating scabies effectively and improves patient care and management in real time. [ABSTRACT FROM AUTHOR]
