It is recommended to go to the hospital and let the doctor check and listen to the situation of bronchitis or bronchopneumonia, and if necessary, take a chest X-ray and check the blood count to see the degree of infection. If the infection is mild, you can take oral anti-inflammatory and cough medicine to treat it; if the infection is severe, you need to apply antibiotics intravenously to anti-infection treatment, along with nebulized inhalation therapy, such as nebulized inhalation budesonide, terbutaline, etc. Pay attention to keep warm, avoid getting cold, choose light and easy-to-digest food, and avoid going to places where people gather to avoid cross-infection.
