Scabies is a parasitic infection known all over the world and particularly in a low socioeconomic context and in institutions. The transmission is mainly direct from skin-to-skin. An increase of cases has been observed in Geneva since October 2011. To confirm the diagnosis, a precise clinical and microbiological examination is required and highly recommended before starting a treatment. Scabies management includes treatment of the patient and his close contacts with antiparasitic drugs as well as thorough cleaning of clothes and bed linen. When available, oral ivermectine is the treatment of choice, topical permethrine is prescribed when ivermectine cannot be used or in association with it in severe presentations. In Switzerland, ivermectine is not readily available, it is expensive and not reimbursed by insurances.
