If your baby’s fever does not go down, first of all, you should monitor the temperature. If the temperature is greater than 38.5℃, you should immediately give symptomatic treatment such as fever reduction. If it is a viral infection, the course of the disease is usually about 7-10 days, you can give anti-viral drugs, such as the four seasons anti-viral particles, pediatric anti-sensitive particles, etc.. If it is a bacterial infection, anti-inflammatory and antipyretic treatment should be given, and oral cephalosporins or macrolides can be given, after seeing a doctor and following medical advice.
