Measles is a common and very infectious viral disease. children before 14 years old are the most possible infected people. Children caught this disease will have fever, coryza, conjunctivitis, and cough. Generalized lymphadenopathy may be found, and tiny white spots on a bright red background, Koplik’s spots, are present on the buccal mucosa of the cheeks.
After 3 or 4 days a florid rash appears, and spread downwards from the head and neck to cover the whole body. The earlier lesiond are more numerous and become confluent and blotchy. The rash begins to fade by the third day and the child’s general condition improves steadily.
There is a live attenuated vaccine which is used in many countries now. It was introduced in the UK in 1968. If sufficient children are immunized epidemics of measles should cease.
In the USA where measles immunization has been widely accepted for some time, measles was virtually eliminated, but there is concern that measles continues to be seen in young children before they are immunized and in young adults.
