A temporary increase in the body’s temperature is referred to as a fever. Having a fever is mostly a sign of some other disease or infection. More specifically, an individual has a fever if the body temperature goes above 36–37°C (98–100°F).
As you know the normal body temperature is 37°C. Therefore, if the temperature rises, it becomes uncomfortable at times. However, in infants, a minor increase in temperature may indicate a severe infection. Fever generally goes away in a few days. Your doctor may recommend medications to control the condition.
