Flu symptoms and possible complications

 

Flu Symptoms

Mild to severe illness can be caused by influenza (flu), and at times can lead to death. Flu is not similar to a cold which usually comes suddenly. People having flu often feel some or all of the below symptoms:

  • fever or feeling feverish/chills
  • cough
  • sore throat
  • runny or stuffy nose
  • muscle or body aches
  • headaches
  • fatigue (tiredness)
  • Some people may have vomiting and diarrhea, though this is more common in children than adults.

It’s important to take into account that not everyone with flu will have a fever.

 

 

 

Flu Complications

Recovery from flu in most people can be in a few days to less than two weeks, but some people will develop complications (such as pneumonia) as a result of flu, some of which can be life-threatening and result in death.

Examples of moderate complications from flu are sinus and ear infections while pneumonia is a serious flu complication that can result from either influenza virus infection alone or from co-infection of flu virus and bacteria. Inflammation of the heart (myocarditis), brain (encephalitis) or muscle (myositis, rhabdomyolysis) tissues, and multi-organ failure for example, respiratory and kidney failure are other possible serious complications which are triggered by flu. Extreme inflammatory response can be triggered in the body by flu virus infection of the respiratory tract can trigger and can lead to sepsis, the body’s life-threatening response to infection. Chronic medical problems can become worse by flu. For example, asthma attacks may be experienced by people having asthma while they have flu, and people with chronic heart disease may experience a worsening of this condition triggered by flu.

Anybody can get sick with flu healthy or unhealthy, and serious problems associated to flu can happen at any age, but some people have a risk of developing serious flu-related complications high if they get sick which includes people aged 65 years and older, people of any age having some chronic medical conditions such as asthma, diabetes, or heart disease, pregnant women and children aged younger than 5 years, but especially those aged younger than 2 years old.
