A fever is a temporary increase in your body temperature, often caused by an infection. A normal body temperature is around 98.6°F (37°C). A fever can cause an increase in body temperature to 100.4°F (38°C) or higher. A low-grade fever isn’t usually a cause for concern, but a high fever can indicate a serious infection.
A fever is often accompanied by other symptoms, such as chills, body aches, and a general feeling of being unwell. If you have a fever, it’s important to drink plenty of fluids and get rest. In most cases, a fever will go away on its own. If your fever is accompanied by a severe headache, rash, or other concerning symptoms, you should see a doctor. In some cases, a fever may be a sign of a more serious condition, such as meningitis or sepsis. If you have a fever and are concerned about your health, it’s always best to consult with a medical professional.
