Winter and spring are high seasons for measles and you need to be alert. Whether it’s prevalent or not, it’s always good to know and be on guard. What kind of disease is measles? Measles is an acute respiratory infection caused by the measles virus that occurs mainly in children. Measles is common in winter and spring, but there are also cases in other seasons. Patients spread the disease by coughing and sneezing. The measles patient is the only source of infection, and measles virus is present in conjunctival secretions, nasal, oropharyngeal, and tracheal secretions from 2 days before onset to 5 days after rash onset, while those with whistling complications are still infectious 10 days after rash onset. The virus is transmitted to others in the form of droplets when the patient coughs or sneezes, making measles very contagious. Measles is characterized by fever and rash. Children are more likely to develop pneumonia, myocarditis, and encephalitis. Can adults get measles? Measles in children has many comorbidities, and in pediatrics measles is still a relatively aggressive disease. However, due to widespread vaccination against measles, pediatric measles patients are becoming less common, and many pediatricians rarely see measles patients. Adult measles is becoming more common due to the increase in the mobile population and the decrease in vaccination rates. Adult measles mainly presents with high fever, malaise, and rash. Complications such as pneumonia, bronchitis, and myocarditis are relatively rare in children, and the prognosis is good. Do not panic even if you get sick. Prevention: Vaccination. Measles is an infectious disease that can be prevented or eliminated through measles vaccination. China has controlled pandemics since 1965, when universal measles vaccination began. Measles vaccination provides protection for at least 20 years if immunization is successful. The measles vaccine has an immunization rate of 85% when a child receives the first dose at 8 months of age and 99% when the vaccine is repeated at 18 months. Infants and children need to be vaccinated according to the schedule and not to miss the vaccination. Children who need to be vaccinated according to the age of the month must complete the vaccination and try not to delay it. Pay attention to open windows and ventilation at home Reduce access to public places, especially for infants and children. Everyone pay attention and take precautions, and measles will stay away from us.
