Large Nosocomial Outbreak Associated with a Norwegian Scabies Index Case Undergoing TNF-α Inhibitor Treatment: Management and Control

We describe a large outbreak associated with a crusted (Norwegian) scabies case in an immunocompromised patient following treatment with TNF-α inhibitor (adalimumab) for psoriasis arthritis. The increasing use of TNF-α inhibitors should induce clinicians to consider this serious parasitic infection when evaluating skin rashes in patients receiving biologic therapies. Infect. Control Hosp. Epidemiol. 2015;36(11):1358–1360
