Measles is caused by a morbillivirus, a member of the paramyxoviridae. The prodromal symptoms of measles such as fever, malaise, and conjunctivitis with photophobia, typically begin after an incubation period of ten days.
Bluish white spots with a bright red rim (Koplik's spots) appear on the palate and/or buccal mucosae early. The typical maculopapular eruption begins typically on the head and neck extending to the trunk and limbs.
Commonly, bullae may develop within the eruption.
The eruption fades within two weeks, often with a fine desquamation.
- There is no effective treatment.
- Immunization with live attenuated virus is highly effective in preventing measles.
