Bronchitis in children can be cured without injections, because the principle of treatment is to take oral medication as much as possible, and then choose infusion therapy if oral medication does not relieve. The fact that children have poor body resistance and low immunity is particularly likely to lead to recurrent bronchitis infections. The actual bronchitis of a child can be caused by viruses, bacteria, mycoplasma, chlamydia and so on. For patients with bronchitis due to bacteria, mycoplasma, chlamydia, you can take oral cephalosporin, azithromycin, etc. to control the infection, for viral infection caused by the choice of antiviral drugs, if oral medication for three days symptoms do not improve then choose infusion treatment.
