A concerning fever for adults is any temperature above 100.4°F (38°C). This kind of fever can be a sign of an underlying illness or infection, and should be taken seriously. Some of the most common causes of fever in adults include the flu, pneumonia, urinary tract infections, and other viral or bacterial infections.
When a fever is accompanied by other symptoms, such as body aches, chills, sore throat, cough, fatigue, or difficulty breathing, it can be a sign of something more serious, such as sepsis or meningitis. If the fever persists for more than three days, or if it is accompanied by any of the mentioned symptoms, it is important to seek medical attention.
In general, it is best to take action as soon as possible when a concerning fever is present. The sooner you seek treatment, the easier it will be to diagnose and treat the underlying condition. Your doctor may order tests such as blood work or imaging scans to help determine the cause of the fever. They may also prescribe medications to help reduce the fever and alleviate any associated symptoms.
It is important to note that fevers can be caused by more serious conditions, such as cancer or autoimmune diseases. Therefore, if you have a fever that persists for more than three days, or if it is accompanied by other symptoms such as body aches, chills, or difficulty breathing, it is important to seek medical attention as soon as possible.
