what is a high fever for an adult

According to multiple sources, a high fever in adults is generally considered to be 103°F (39.4°C) or higher. However, it is important to note that body temperature can vary slightly from person to person and at different times of the day, and there is no strict guideline for what temperature is considered a fever. If an adult has a fever over 104°F (40°C), they should call their doctor, and if they have a fever along with symptoms such as seizures, loss of consciousness, confusion, stiff neck, trouble breathing, severe pain anywhere in the body, swelling or inflammation of any part of the body, lack of desire to eat, rash, restlessness, weakness, or extreme sleepiness, they should seek medical help right away.
