Generally speaking, acute laryngitis in children is accompanied by fever, as it is caused by viral or bacterial infection. Inflammatory response: redness, swelling, heat, and pain. Local reaction: In children, local infections can easily lead to systemic symptoms, especially fever, which can vary in intensity but generally remains relatively easy to reduce. It is unlikely to be extremely high fever. If the body temperature exceeds 38 degrees Celsius, or if the child shows poor spirits during fever, oral antipyretics or rectal fever suppositories can be used to alleviate the symptoms of fever.
