Measles is preventable by immunization but high levels of coverage are required to prevent outbreaks of disease from occurring.
No specific treatment for measles is available except for supportive care.
Complications of measles are more common in immunocompromised and poorly nourished individuals and include pneumonia, laryngotracheitis, otitis media, and encephalitis.
Measles is a highly infectious disease caused by measles virus, characterized by a maculopapular rash, cough, coryza, conjunctivitis, and a pathognomonic enanthem (Koplik spots) with an incubation period of about 10 days.
