Bellin Flu Facts
People don’t realize that every fall and winter flu is a problem that has to be managed. Somewhere between five and 20 percent of the country’s population gets the flu every year, which amounts to millions of cases. For most, the flu is a few days of feeling as if you’ve been hit by a truck. For some, flu leads to dangerous complications. What’s the difference, who’s at risk and how do you manage that risk?

Do You Know the Symptoms of Influenza?
Influenza (commonly called the "flu") is a contagious respiratory illness caused by influenza viruses. The information below describes common flu symptoms, how to protect yourself and those close to you from getting the flu, and what to do if you get sick with flu-like symptoms.
Be aware of common flu symptoms
Influenza usually starts suddenly and may include the following symptoms:
- Fever (usually high)
- Tiredness (can be extreme)
- Sore throat
- Runny or stuffy nose
- Body aches
- Diarrhea and vomiting (more common among children than adults)
Having these symptoms does not always mean that you have the flu. Many different illnesses, including the common cold, can have similar symptoms.
Diagnosing the flu
It is very difficult to distinguish the flu from other infections on the basis of symptoms alone. A doctor's exam may be needed to tell whether you have developed the flu or a complication of the flu. There are tests that can determine if you have the flu as long you are tested within the first two or three days of illness.
If you develop flu-like symptoms and are concerned about your illness, especially if you are at high risk for complications of the flu, you should consult your health care provider.
Those at high risk for complications include people 65 years or older, people with chronic medical conditions (such as asthma, diabetes, or heart disease), pregnant women, and young children.
Know the risks from the flu
In some people, the flu can cause serious complications, including bacterial pneumonia, dehydration, and worsening of chronic medical conditions, such as congestive heart failure, asthma or diabetes. Children and adults may develop sinus problems and ear infections.
People may have different reactions to the flu
The flu can cause mild to severe illness and at times can lead to death. Although most healthy people recover from the flu without complications, some people, such as older people, young children, and people with certain health conditions (such as asthma, diabetes, or heart disease), are at high risk for serious complications from the flu.
Know how the flu spreads
The flu usually spreads from person to person in respiratory droplets when people who are infected cough or sneeze. People occasionally may become infected by touching something with influenza virus on it and then touching their mouth, nose or eyes.
Healthy adults may be able to infect others one day before getting symptoms and up to five days after getting sick. Therefore, it is possible to give someone the flu before you know you are sick as well as while you are sick.
Best protection against the flu: Vaccination
The single best way to protect yourself and others against influenza is to get a flu vaccination each year. The "flu shot" — an inactivated vaccine (containing killed virus) that is given with a needle, usually in the arm. The flu shot is approved for use in people older than 6 months, including healthy people and people with chronic medical conditions (such as asthma, diabetes, or heart disease).
Yearly flu vaccination should begin in September or as soon as vaccine is available and continue throughout the influenza season, into December, January, and beyond. This is because the timing and duration of influenza seasons vary. While influenza outbreaks can happen as early as October, most of the time influenza activity peaks in January or later.
