Measles
What is Measles?
Measles (rubeola) is a highly contagious infection of the respiratory system, which is caused by a virus. The incubation period is usually asymptomatic and lasts from 10-14 days. This is followed by a prodromal period of two to three days, which is accompanied by redness of the eyes, nasal discharge, and cough. An eruption inside the mouth, called Koplik's spots, may occur, is only found in measles, and may precede the rash by a couple days. The characteristic rash starts on the face, then moves down the neck to the trunk and finally the extremities. The patient typically starts to improve within 48 hours of the appearance of the rash, although cough may persist for one to two weeks thereafter.
