Fever with sore throat in children is usually caused by upper respiratory tract infection. The cause of the infection may be related to a viral or bacterial infection caused by the child’s cold. This condition usually needs to be treated with oral medication. You can take Lianhua Qingfei capsule or cold and fever granules orally. Also take acetaminophen or ibuprofen for treatment. You can drink more water and keep warm to avoid further exposure to cold, so that the child will generally recover quickly.
