People who have flu often feel some or all of these symptoms:. Most people who get flu will recover 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. Sinus and ear infections are examples of moderate complications from flu, while pneumonia is a serious flu complication that can result from either flu virus infection alone or from co-infection of flu virus and bacteria.
Other possible serious complications triggered by flu can include inflammation of the heart myocarditis , brain encephalitis or muscle tissues myositis, rhabdomyolysis , and multi-organ failure for example, respiratory and kidney failure. 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.
Anyone can get sick with flu, even healthy people, and serious problems related to flu can happen to anyone at any age, but some people are at higher risk of developing serious flu-related complications if they get sick. This includes people 65 years and older, people of any age with certain chronic medical conditions such as asthma, diabetes, or heart disease , pregnant people and children younger than 5 years, but especially those younger than 2 years old.
