What causes children to have recurring fever?

Because children have relatively weak resistance, it is very common for them to get sick. Sometimes children will have fever symptoms due to bacterial infection. With active treatment, some children's fever will subside quickly, but some children will often have repeated fevers, which is very troublesome. So, why do children have recurring fevers?

1. Fever of unknown cause: Fever of unknown cause refers to fever caused by various unclear reasons. The main characteristic of this unexplained fever is that the fever persists for more than 3 weeks and the body temperature is above 38.5 degrees. If the fever is caused by this reason, the doctor will usually ask the patient's medical history in detail and do various routine laboratory tests.

2. Non-infectious fever: Non-infectious fever refers to a fever that is not caused by various infectious diseases, some pathogenic substances or various inflammations. Usually this kind of fever is caused by dysfunction of the body's temperature center or other reasons, resulting in excessive heat production and poor heat dissipation.

3. Central fever: Central fever is one of the main causes of children's fever. It is generally believed that if you treat this kind of fever, in addition to paying attention to the fever caused by abnormalities of the higher central nervous system, you should also pay attention to whether the fever is caused by other sources of infection. It is best to do a good job of checking the causes of infection throughout the body in order to prescribe the right medicine.

4. Continuous fever: The main characteristic of this type of fever is that it recurs repeatedly, and the temperature of the fever can also be divided into different levels.

No matter what causes the fever, parents should pay great attention to it, because if the child has a high fever and the fever does not subside for a long time, it may damage the brain and leave lifelong disability. However, do not abuse antipyretics. If the child's temperature does not exceed 38.5 degrees, physical cooling can be sufficient.
