A child with a dry cough and fever, often caused by pharyngitis, is likely to have pneumonia or bronchitis caused by a pathogenic infection. If there is congestion and edema in the throat, it is a dry cough and fever caused by inflammation of the throat, and you need to use medications that are effective in treating laryngitis, such as Pudilan Anti-inflammatory Oral Liquid or Blue Scutellaria Oral Liquid. If the effect is not good, it is likely to be combined with a bacterial infection, which needs to be treated with antibiotics, such as pediatric cefixime granules or pediatric cefadroxil. If bronchitis or pneumonia caused by mycoplasma occurs, chest imaging and positive antibodies to mycoplasma are diagnostic, and intravenous treatment with macrolide antibiotics is required. If the symptoms of cough are more serious, you can nebulize or take oral cough expectorant drugs for symptomatic treatment.
