why do children get fevers

Summary

Fevers in children are usually caused by an infection, which stimulates the body's immune system to fight the infection and makes it harder for germs to grow. 1 Infants are more at risk of serious infection even with a low fever. 2 Fevers are caused by an imbalance of heat production and heat loss in the brain's hypothalamus. 2 To prevent fevers, it is important to get vaccinated, follow public health guidelines, and wash hands often. 2 Fever in children is caused by the hypothalamus setting the body temperature above its normal level in response to an infection with germs. 3
