It is essential that providers maintain a high level of suspicion for measles in persons with febrile rash illness who have recently traveled or have had contact with travelers and are able to recognize its clinical features (8). Measles is characterized by a prodrome of fever (up to 40.6 °C), cough, coryza, and conjunctivitis. A characteristic red, blotchy, “morbilliform” rash appears 2 to 4 days after symptom onset (Figure 1); it typically begins on the face before spreading downward and becoming confluent (8). Pathognomonic Koplik spots appear 1 to 2 days before the rash and last 2 to 3 days; they are small, slightly raised, bluish-white spots on an erythematous base and have been reported in 60% to 70% of patients with measles, although they are probably present in all cases (Figure 2) (7, 9). Measles rash may be confused with other viral exanthems (erythema infectiosum [fifth disease] or roseola), Kawasaki disease, or scarlet fever. Immunocompromised patients may not develop a characteristic rash (7). Complications are common in young children and include diarrhea, otitis media, bronchopneumonia, and croup; acute encephalitis occurs in 1 per 1000 cases and can lead to permanent brain damage. Death occurs in 1 to 3 per 1000 reported cases and is most common in young children or immunocompromised patients (1).
