What is influenza (also called flu)?

The flu is a contagious respiratory illness caused by influenza viruses that infect the nose, throat, and lungs. It can cause mild to severe illness, and at times can lead to death. The best way to prevent the flu is by getting a flu vaccine each year.

Signs and symptoms of flu

People who have the flu often feel some or all of these signs and symptoms:
•    Fever* or feeling feverish/chills
•    Cough
•    Sore throat
•    Runny or stuffy nose
•    Muscle or body aches
•    Headaches
•    Fatigue (very tired)
•    Some people may have vomiting and diarrhea, though this is more common in children than adults.
*It’s important to note that not everyone with flu will have a fever.

How flu spreads:   Most experts believe that flu viruses spread mainly by droplets made when people with flu cough, sneeze or talk. These droplets can land in the mouths or noses of people who are nearby. Less often, a person might also get flu by touching a surface or object that has flu virus on it and then touching their own mouth, eyes or possibly their nose.
 
Period of contagiousness: You may be able to pass on the flu to someone else before you know you are sick, as well as while you are sick. Most healthy adults may be able to infect others beginning 1 day before symptoms develop and up to 5 to 7 days after becoming sick. Some people, especially young children and people with weakened immune systems, might be able to infect others for an even longer time.
Certain people are at greater risk for serious complications if they get the flu. This includes older people, young children, pregnant women and people with certain health conditions (such as asthma, diabetes, or heart disease).

Flu seasons are unpredictable and can be severe. Over a period of 30 years, between 1976 and 2006, estimates of flu-associated deaths in the United States range from a low of about 3,000 to a high of about 49,000 people.
 
Complications of flu: Complications of flu can include bacterial pneumonia, ear infections, sinus infections, dehydration, and worsening of chronic medical conditions, such as congestive heart failure, asthma, or diabetes.

Prevent seasonal flu: Get vaccinated
The single best way to prevent the flu is to get a flu vaccine each season.

 

Stop Smoking Now!

"Again, the evidence is clear that quitting smoking will reduce cancer. If you need help quitting, just ask us!" Dr Dunn

Study links one-third of cancer deaths in U.S. to cigarettes. American Cancer Society data showed about a third of U.S. cancer deaths are linked to cigarette smoking, and researches said reducing smoking rates should be a top public health priority.  The study, published in the annals of Epidemilogy, did not include deaths from secondhand smoke or from use of other tobacco products, such as cigars and smokeless tobacco.  HealthDay News (12/9)
