38.0℃ is a fever, and clinically it is called a fever if the body temperature is greater than 37.3℃. If the body temperature is only 38.0℃, there is usually no need to take medication, and the body temperature can be brought down to normal by physical cooling, for example, by drinking a lot of warm water, taking warm baths, alcohol rubbing baths, and covering the forehead with warm towels. If the body temperature is 38.0℃ and there is obvious discomfort, you can consider taking oral antiviral medication, such as Four Seasons Antiviral Combination or Pudilan Anti-inflammatory Oral Liquid for symptomatic treatment. If the temperature does not go down or recede, go to the hospital to find out the cause of the fever and then take appropriate treatment.
