True, fevers are extremely common, and COVID-19 certainly brought its fair share of high-temperature days to those infected. Fever, like COVID, is your immune system's response to an infection or other invader. It is defined as a temperature of 100.4 °F or higher. Your elevated temperature is a clear indication that something is wrong.
Most fevers will go away if you take an over-the-counter fever reducer like acetaminophen (Tylenol) or ibuprofen (Advil). If yours does not, speak with your doctor.
A fever that is too high is determined by a number of other factors. If you're over the age of 65 or immunocompromised, especially if you've been exposed to COVID-19, call your doctor if your fever rises above 101°. Anyone with a fever of 103°F or higher should take the same precautions. If your temperature rises above 105°F, go to the nearest emergency room.
