  1. An acute exanthematous disease, caused by measles virus (genus Morbillivirus), a member of the family Paramyxoviridae, and marked by fever and other constitutional disturbances, a catarrhal inflammation of the respiratory mucous membranes, and a generalized dusky red maculopapular eruption; the eruption occurs early on the buccal mucous membrane in the form of Koplik spots, a manifestation useful in early diagnosis; average incubation period is from 10–12 days. Recovery is usually rapid, but respiratory complications and otitis media caused by secondary bacterial infections are common. Encephalitis occurs rarely. Subacute sclerosing parencephalitis may occur later and is associated with chronic infection.
