A child’s cough at the onset of a cold suggests a poor immune system and insufficient resistance to bacterial or viral attack. Usually children with cold are prone to complicate cough, runny nose, sneezing and other symptoms, which should be dealt with in combination with clinical symptoms and addressed from two aspects: treating the cold and improving immunity. I. Treatment of cold: 1. If the symptoms are not accompanied by fever, just a simple cold and cough, you can give your child cold medicine, such as pediatric cold granules, pediatric pharyngeal flat granules, pediatric lung-clearing and phlegm-transforming granules, pediatric cough syrup, etc., to relieve the symptoms of your child’s cold and cough; 2. If the cold and cough is accompanied by fever symptoms, it is recommended to promptly go to the hospital to check the blood routine, to clarify whether the cold and cough is caused by viral or 2. If the cough is accompanied by fever, it is recommended to go to the hospital for blood tests to determine whether the cough is caused by viral or bacterial infection. If the cold and cough is caused by a viral infection, you can give your child antiviral medication, such as Blue Scutellaria Oral Liquid. If the increase in white blood cells indicates a bacterial infection, antibiotics, such as azithromycin, should be taken under the guidance of a doctor. 2. Improving immunity: 1. Oral medication: When a child coughs when he has a cold, it means that his immunity is relatively low, so he can take transfer factor oral solution to enhance his immunity as prescribed by the doctor. 2. Enhance the child’s resistance and prevent frequent colds and coughs.
