Measles is contagious and is an acute respiratory infection caused by the measles virus. Measles is spread mainly through respiratory secretions and droplets, mostly in children, and is a category B national infectious disease, usually prevalent in winter and spring. If a patient with measles or a suspected patient is found in the clinic, he or she needs to be reported to the infection card and given isolation treatment. Early clinical features of measles are mainly fever, runny nose and cough, accompanied by specific measles mucosal spots, extensive trunk skin maculopapular rash, and with complications such as otitis media, bronchitis and pneumonia. There are no specific anti-measles virus drugs, but with live attenuated measles vaccination, its incidence has decreased significantly. In case of measles, hospital dermatology should be consulted promptly for standardized treatment by a professional doctor. To avoid measles, susceptible patients should avoid public places, especially densely populated places with poor air circulation, such as shopping malls, supermarkets, theaters, game halls, etc. Pay attention to keeping rooms ventilated, exposing clothing to the sun, and eating a reasonable diet.
