If the child has repeated cough and fever, consider the presence of infection. The infectious agent may be bacteria, virus or mycoplasma, and the infectious disease may be bronchitis or bronchopneumonia, but if the child has repeated cough and fever, bronchopneumonia is more likely. Parents are advised to take the child to the hospital for routine blood tests, mycoplasma antibodies, lung CT and other related tests, and to treat according to the test results. If the test results are not serious, you can take some oral medication, such as cephalosporin antibiotics, penicillin antibiotics, etc. If there is mycoplasma infection, you can take azithromycin and roxithromycin orally, as well as herbal medicines to clear heat and detoxify the toxin, such as Pu Di Lan anti-inflammatory oral liquid and pediatric black beetle and clear fever granules. If the cough is obvious, cough medicine can be chosen from the oral liquid for coughing and wheezing of children with lung fever, oral liquid for coughing and coughing of children, and etanercept, etc. Nebulized inhalation can also be done to stop coughing and resolve phlegm. In addition, if the above treatment does not work well, parents are advised to take the child to the hospital and give intravenous infusion treatment.
