Fever and chills with colds are likely to be high, most of them will be over 39℃, so pay attention to the change of body temperature. If the body temperature exceeds 39℃, you can first take oral ibuprofen, nimesulide, acetaminophen for cooling treatment, and also need to drink more warm water and appropriate light salt water to replenish the lost water. If you have a cold or fever, you should pay attention to adding or removing clothes at the right time, and you should not cover the quilt or clothes excessively, which is not conducive to heat dissipation and temperature drop. If the fever does not subside, it is recommended to go to the hospital for blood tests and C-reactive protein, and then treat the symptoms.
