The patient history is notable for exposure to the virus. The incubation period from exposure to onset of measles symptoms ranges from 7 to 14 days (average, 10-12 days). Individuals are contagious 1-2 days before the onset of symptoms. Persons with measles are contagious 3-5 days before the appearance of the rash through 4 days after the onset of rash. Immunocompromised individuals can be contagious throughout the duration of the illness.
Modified measles is a milder form of measles that occurs in individuals who have received serum immunoglobulin after their exposure to the measles virus. Similar but milder symptoms and signs may still occur, but the incubation period may be as long as 21 days.
