Children with fever and hoarse throat are mainly caused by upper respiratory tract infection caused by bacterial or viral invasion, resulting in symptoms triggered by mucosal damage. If the fever is viral, antiviral drugs such as ribavirin can be given as symptomatic treatment. If it is caused by bacterial infection, antibiotics can be given as symptomatic treatment, such as penicillins, cephalosporins, macrolides. Oral Chinese medicine can also be taken, such as Pu Di Lan Anti-inflammatory Oral Liquid, Blue Scutellaria Oral Liquid, Shuang Huang Lian Oral Liquid, Lian Hua Qing Fei Qing Granules, etc. to clear heat and detoxify the toxin. It can be treated by combining Chinese and Western medicine, which can shorten the cycle and improve efficiency.
