Emergency department management of measles, mumps, rubella, and varicella in pediatric patients.

Public health programs have helped decrease the prevalence and sequelae of measles, mumps, rubella, and varicella; however, misinformation regarding vaccinations and recent disruptions to vaccination programs have caused outbreaks to occur. Emergency clinicians must be able to readily identify the characteristic presentations of measles, mumps, rubella, and varicella, with the goals of optimizing supportive care, limiting the spread of disease, and giving appropriate precautionary advice for complications to patients and their families. This issue provides a review of the clinical features, differential diagnoses, potential complications, and treatment options for measles, mumps, rubella, and varicella.
