The child’s recurrent fever depends on the specific manifestation of the fever course, which may be the normal course of the disease, such as pneumonia, Kawasaki disease, etc.; or it may be the manifestation of the disease’s prolongation or even gradual aggravation, such as upper respiratory tract infections and tuberculosis infections.
1. Normal course of the disease: more serious infections such as pneumonia, encephalitis, etc., even if timely treatment, will show repeated fever in the recovery process, but with the treatment, the fever peak will slowly decline, fever will gradually shorten; in addition, some immune diseases such as Kawasaki Disease, etc., may also appear similar to the above situation.
2. Delayed or aggravated diseases: In mild infectious diseases such as upper respiratory tract infections, repeated fever may occur when the disease is delayed or aggravated, and the peak of fever may increase and the duration of fever may be prolonged; in addition, in tuberculosis infections, recurrent low-grade fever may occur due to the progression of the disease or gradual aggravation of the disease.
It is recommended that parents who find that their children have recurrent fever should take their children to the hospital in time to avoid delays.
