Nosocomial outbreak of scabies

Scabies is a common infestation caused by the human itch mite Sarcoptes scabiei. Small outbreaks in communities or hospitals are not uncommon, but are rarely documented. In this paper, we report on a nosocomial outbreak of scabies originating from a patient with Norwegian scabies at the Intensive Care Unit in Taiwan Provincial Tainan Hospital. Twenty-nine individuals including four inpatients and 25 hospital personnel were involved. The diagnosis was based on history, clinical findings or a positive skin scraping. Unfamiliarity with the clinical manifestations delayed the diagnosis and the highly contagious nature of Norwegian scabies precipitated this outbreak. Early initiation of effective control measures with extensive therapeutic and prophylactic treatment of all contacts resulted in successful eradication of the outbreak.
