The normal body temperature is about 36 -37 degrees. Different individuals, at different times of the day, in different states (such as exercise, after meals, menstrual period, pregnancy and high temperature environment), but the fluctuation range does not exceed 65438 0 degrees. So as far as the symptoms you provide are concerned, I think your child's problems should be considered normal.
Guiding opinions:
I suggest that if the child has no other symptoms, such as headache, fatigue, loss of appetite, etc. And there is nothing abnormal in the blood test, so you should consider it as bronchitis. Archie can be used, with broad antibacterial spectrum and symptomatic treatment. If you cough, stop coughing and treat it with phlegm.
Life care:
Give children plenty of water and eat foods rich in vitamins, such as fresh fruits and vegetables.
