Measles is an acute respiratory infectious disease caused by the measles virus. The main symptoms include fever, cough, runny nose, conjunctivitis, oral measles mucosal spots, and skin maculopapular rashes. Simple measles is easy to treat with a good prognosis. However, individuals in poor general condition or with low immunity may develop a severe form of measles with a higher mortality rate. There is no specific antiviral treatment for measles; treatment is mainly supportive and symptomatic. For high fever, small doses of antipyretics or physical cooling measures should be used, but the body's temperature should not be reduced to normal as this can delay the appearance of the rash and prolong the illness. Cough suppressants and expectorants can be used for coughing. For weak or severely ill children, early injection of immunoglobulin is recommended, followed by the prevention and treatment of complications such as laryngitis, pneumonia, myocarditis, and encephalitis.
