What tempurture is a fever?

A fever is generally considered to be a body temperature of 100.4 degrees Fahrenheit (38 degrees Celsius) or higher. However, it is important to note that normal body temperature can vary from person to person, and a slight elevation may not necessarily indicate a fever. Additionally, some individuals may experience a low-grade fever (between 99.5 and 100.3 degrees Fahrenheit) due to various factors such as exercise, stress, or certain medications. In such cases, it is advisable to monitor the temperature and consult a healthcare professional if it persists or is accompanied by other symptoms.
