Measles is a highly contagious viral disease that mainly affects children. It is transmitted via droplets from the nose, mouth or throat of infected persons. Initialsymptoms usually appear 10-12 daysafter infection, and include high fever, runny nose, bloodshot eyes, and tiny white spots on the inside of the mouth. Several days later, a rash develops, starting on the face and upper neck and gradually spreading downwards.
Measles can be prevented by immunization. There is no specific treatment, and most people recover within 2-3 weeks. However, measles can cause serious complications, including blindness, encephalitis, severe diarrhea, ear infections and pneumonia, particularly in malnourished children and people with reduced immunity.
