A body temperature of 99.8 degrees Fahrenheit (37.7 degrees Celsius) is considered slightly elevated, but it is not typically considered a fever. A fever is generally defined as a body temperature of 100.4 degrees Fahrenheit (38 degrees Celsius) or higher. However, it’s important to note that a temperature reading alone cannot determine if someone has COVID-19. Other symptoms, such as coughing, shortness of breath, and loss of taste or smell, as well as exposure to someone with the virus, are also important factors to consider. If you’re concerned about your symptoms, it’s best to consult with a healthcare professional.
