Flu Symptoms & Complications

Influenza (flu), also known as the “flu,” can sometimes result in death and cause mild to severe disease. Symptoms of the flu typically appear suddenly.

  • fever
  • cough
  • sore throat
  • runny or stuffy nose
  • muscle or body aches
  • headaches
  • fatigue

Complications of flu:

The majority of individuals who contract the flu recover in a few days to less than two weeks, but some people may experience complications (including pneumonia) as a result of the flu, some of which can be fatal.

Flu virus infection of the respiratory tract can trigger an extreme inflammatory response in the body and can lead to sepsis, the body’s life-threatening response to infection. Flu also can make chronic medical problems worse. For example, people with asthma may experience asthma attacks while they have flu, and people with chronic heart disease may experience a worsening of this condition triggered by flu.

A respiratory flu virus infection can cause a severe inflammatory reaction in the body, which can progress to sepsis, the body’s life-threatening infection response. The flu can exacerbate existing medical conditions. For instance, those who have asthma may experience asthma episodes while they have the flu, and those who have chronic heart disease may see their condition get worse as a result of the flu.
