Cold, cough and runny nose in babies are symptoms of respiratory tract infection. If it is caused by a viral infection, antiviral and topical oral and nasal medication can be given, such as oral Four Seasons antiviral combination and ribavirin spray at the mouth and nose, most of them will be cured in 7-10 days. If the cough has phlegm, cough with wheezing, and the symptoms are heavy and breathing is increased, it may be bronchitis or bronchopneumonia, and antibiotics such as cefixime granules or azithromycin granules should be given, supplemented with cough and phlegm medicines, such as orange shell combined, etanercept, etc. The course of the disease is about 1 week. If the baby’s mental state is poor, go to the hospital in time to avoid delaying the disease.
