what is a low grade fever for adults

A low-grade fever is a slightly elevated body temperature above what is considered normal, but below the temperature range that is considered a fever. There is no standard temperature range for a low-grade fever, but most sources agree that it falls between 99°F (37.2°C) and 100.4°F (38°C) . Some sources define it as a temperature between 100.4°F (38°C) and 102.2°F (39°C) . A low-grade fever is usually caused by a viral or bacterial infection, and it is often the first sign of an illness. It is usually accompanied by mild symptoms such as body aches, headaches, fatigue, and stomach upset. A low-grade fever usually does not require treatment unless it is occurring in a very young infant or is accompanied by other worrisome symptoms such as confusion or the inability to eat or drink without vomiting. To bring down a fever without medication, it is recommended to wear minimal clothing or bathe in lukewarm or cool water and drink plenty of fluids to keep the body hydrated. If a fever lasts longer than three to five days or does not improve, it is recommended to see a doctor.
