What is Fever?
Fever is when your body temperature rises above its normal range. Usually, a normal body temperature is around 98.6°F (37°C). However, it can vary a little from person to person. If your temperature goes above 100.4°F (38°C), doctors call it a fever. Often, fever is your body’s way of fighting off germs or infections. Because of this, it is a common sign that something is wrong inside your body.
