Symptoms of a cold and fever can lead to an increase in body temperature, sometimes reaching 38 degrees, or even 39 degrees. In children, there might be acute high fever, even exceeding high fever levels, causing facial redness, red ears, increased heart rate, deepened and quickened breathing, leading to physical weakness, nausea, vomiting, and lack of energy. It is necessary to measure body temperature promptly and adopt corresponding fever reduction treatments based on the degree of fever and specific symptoms. For temperatures below 38 degrees, physical methods like wiping the palms and soles with warm water can be used to reduce fever. For temperatures above 38 degrees, antipyretic analgesics can be taken for symptomatic treatment.
