A 12-year-old child with a fever of 38 degrees should not be overly nervous because a body temperature of 38.5 degrees or less can temporarily eliminate the need for a fever. If your child is uncomfortable, you can start by giving him/her a Chinese antipyretic medicine to relieve the discomfort caused by the fever, such as antelope horn granules will do. If the child has a stuffy nose, runny nose or sore throat, it is more likely that the child has a viral cold. At this time, the child should take Four Seasons Anti-Viral Combination or Aminophenol Pseudomal dispersible tablets, and drink more water and rest, and eat more vitamin-rich fruits and vegetables to help strengthen the child’s resistance and promote recovery from the cold. If there is abdominal pain or diarrhea, the possibility of bacterial enteritis is still relatively high, you need to go to the hospital to check the stool routine, if the diagnosis of bacterial enteritis can be confirmed, it is necessary to give the child antibiotics for treatment.
