The first thing that should be done is to clarify the pathogen causing the bronchitis, whether it is caused by bacterial infection or mycoplasma infection, and the pathogen can be clarified through blood tests, C-reactive protein, and mycoplasma antibody assay. Cephalosporin is a bactericidal agent that is effective for bacterial infections, but it should be noted that alcohol should be avoided during the application of cephalosporin to avoid damage to the body; azithromycin is effective for mycoplasma infections. Therefore, the choice of antibiotics needs to be clear about the pathogen, and patients also need to pay attention to rest and avoid exertion, which can promote the recovery of the disease.
