The flu, also known as influenza, is a highly contagious respiratory illness caused by a virus. The symptoms of the flu can range from mild to severe and can include fever or feeling feverish/chills, cough, sore throat, runny or stuffy nose, muscle or body aches, headaches, fatigue (tiredness), and in some cases, vomiting and diarrhea. However, not everyone with the flu will experience all of these symptoms, and some people may have symptoms not listed. It is important to see a doctor if you suspect you have the flu, especially if you are at high risk for complications from the flu, such as people with weakened immune systems, young children, and older adults. This is because the flu can be a serious illness, and early treatment can help reduce the severity of symptoms and prevent complications. Some of the potential complications of the flu include pneumonia, ear infections, and sinus infections. To prevent the spread of the flu, it is important to take certain precautions, such as getting vaccinated against the flu, washing your hands frequently with soap and water, avoiding close contact with people who are sick, covering your mouth and nose when coughing or sneezing, and staying home from work or school if you are feeling sick.

In some cases, a fever may need to be treated with medication, and your doctor may also recommend other treatments to help manage your symptoms and reduce the risk of complications.
