Abstract

Introduction: Scabies is a parasitic cutaneous infection, which is common in primary care, pediatrics and dermatology. Although it isn’t life threatening it causes considerable morbidity and has a substantial impact in the quality of life. In developing countries it is associated with high rates of cutaneous bacterial superinfection, namely impetigo.

Objectives: To review the general aspects of scabies, with a particular emphasis on the diagnosis and treatment. To analyze the national and international epidemiological situation and the available treatment options, particularly in Portugal.

Material and Methods: Narrative review of the scientific literature, including textbooks and scientific databases (PubMed/Medline, Cochrane, UpToDate, IndexRMP).

Discussion: Scabies is a dermatosis with typical clinical characteristics, namely pruritus, type of cutaneous lesions and their distribution, and presence of epidemiological context. Efficacy of treatment of scabies patients and close contacts depends on a timely diagnosis, and diagnostic delay, low-adherence to treatment and incorrect treatment application should fundamentally be avoided.

Conclusions: Given the efficacy and toxicity of the various treatment options, 5% permethrin and oral ivermectin are considered first-line. However, in Portugal, since neither are available, benzyl benzoate is most frequently used. A careful explanation of treatment steps and its correct application is essential for therapeutic success. In Portugal it would be useful and advisable that scabies becomes a notifiable disease.
