Bronchitis is a common infectious disease of the lower respiratory tract with clinical manifestations of cough and sputum, mostly caused by viral and bacterial infections. Bronchitis infusion does not exceed 5-7 days, unless accompanied by other infectious diseases of the lungs, including pneumonia, lung abscess, tuberculosis, etc., which can extend the treatment cycle. If the bronchiectasis infection is not severe, antibiotic therapy may not be given. If the infection is severe and the total white blood cell count, neutrophils, C-reactive protein, and calcitoninogen are significantly elevated, this indicates a significant bacterial infection and requires oral antibiotics or intramuscular or intravenous antibiotics for a course of no more than 5-7 days. Chronic bronchitis and acute vasculitis can effectively shorten the course of treatment and improve the clinical symptoms of patients if they are treated with herbal medicine. In conclusion, the infusion of bronchitis is 5-7 days, and if there are other symptoms need to give Chinese herbal medicine with the treatment in order to relieve the clinical manifestations of the patient as soon as possible.
