When adults or children suffer from flu, they have fever along with a feeling of sickness all over their body. This ailment causes discomfort and unpleasantness but it is not dangerous.
However, the flu can be a dangerous illness as was seen during the outbreak of flu in the early 20th century causing almost 20 million deaths. On date, approximately 20 thousand people in the US die from this illness annually. The number of people who get this illness is much larger in number. Most people affected by this condition are aged or suffer from advanced stage of some major illness. Almost 1% of children who get flu get serious enough to be hospitalized.
It is true that most people suffer from flu at least once a year. This is more common in school going children and is reported more often in winter season.
The symptoms indicating onset of flu include fever of around 102 to 106 degrees Fahrenheit, flushed appearance of the face, severe loss in energy levels, and body pain. Some people also have other symptoms like vomiting or dizziness. Generally fever caused by flu lasts for almost one or two days. Sometimes it may even last up to 5 days.
When the patient has suffered the illness for 2 to 4 days, the body symptoms reduce and symptoms of respiratory problems occur. Some of them are sore throat, cold, bronchitis, croup, pneumonia or infection in the ears. The most common symptoms of respiratory problems are dry and hacking cough, headache, discharge from the nose, sneezing and sore throat.
