The duration of the flu, or influenza, varies from person to person, but typically it lasts for about one to two weeks. It is important to remember that the virus can remain contagious for up to a week after the symptoms have subsided.
The influenza virus is highly contagious and can cause mild to severe illness. Symptoms of the flu include fever, chills, headache, sore throat, runny or stuffy nose, coughing, body aches, fatigue, and sometimes nausea and vomiting. Symptoms typically begin one to four days after exposure to the virus, and can last from a few days up to two weeks.
In some cases, the virus can cause more severe complications such as pneumonia or bronchitis. These complications can cause the illness to last even longer. People who are younger than five years old, older than 65, or have weakened immune systems are more likely to develop complications from the flu.
Most people will recover from the flu without any medical intervention. However, it is important to take steps to reduce the spread of the virus and to take care of yourself while you are sick. This includes getting plenty of rest, drinking plenty of fluids, using a tissue to cover your nose and mouth when you cough or sneeze, and washing your hands frequently.
If your symptoms become severe or last longer than two weeks, you should contact your healthcare provider. They may recommend antiviral medications to help reduce the severity and duration of the illness.
