Depending on how serious the flu season is, between 750,000 and 1,000,000 people are hospitalized with the flu each year. Thirty to eighty thousand of them will die, with between 50 and 70 percent of them being over the age of 65.
The flu begins with an inflammatory response in the body to fight off infection. That triggers the aches, pains and respiratory distress. The flu virus infects the cells lining the mucous membranes in the throat, nose and bronchial tubes. Bacteria can clog the air sacs in the lungs making it difficult to breathe. Bacteria can then escape into the bloodstream and cause sepsis. One possible outcome of sepsis is organ failure which is how the flu can lead to death.
If you experience any of the following symptoms it is important to seek immediate care:
- Severe weakness or unsteadiness
- Dizziness and confusion
- Extreme muscle pain
- Persistent pain or pressure in the chest or abdomen
- An inability to urinate
- A cough that improves but then returns or worsens
If you think you may be getting the flu, it is important to seek medical treatment immediately and inquire about starting an antiviral medication like Tamiflu. If started within the first 48 hours after the onset of symptoms the flu can be greatly reduced in length and severity.
Getting vaccinated against the flu may be the most important step to preventing or reducing the impact of the flu in the first place.
