Measles is an acute rash-causing respiratory infection caused by the measles virus. It spreads primarily through respiratory droplets and eye conjunctiva contact, making it one of the most contagious diseases. Typical symptoms include fever, runny nose, cough, tearing, photophobia, and maculopapular rashes. A small number of patients may develop complications such as pneumonia, laryngitis, otitis media, myocarditis, or encephalitis, with severe cases potentially leading to death.
