Babies are particularly susceptible to bronchitis due to their low immunity and incomplete development of their own airways. When a baby with bronchitis develops a cough, the first step in treatment is anti-infective therapy. The main pathogens that cause bronchitis in babies include bacteria, viruses, mycoplasma and chlamydia, so choosing targeted medications is a critical step in the treatment of cough. Cephalosporins, penicillin, macrolide antibiotics and antiviral drugs are chosen accordingly to treat different pathogens, while active symptomatic treatment, such as oral cough medicines as acute syrup, pulmonary cough combination, and oral cough solution for children with lung fever and asthma, can be taken to relieve the cough symptoms of bronchitis.
