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 and /or
• Sore throat
May also feel:
• Runny or stuffy nose
• Muscle or body aches
• Fatigue (very tired)
• Some people may have vomiting and diarrhea, though this is more common in children than adults.
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.
Preventing seasonal flu: Get vaccinated AWC Health Service offers the flu shot for $12.00
The single best way to prevent the flu is to get a flu vaccine each season. “Flu shots” — inactivated vaccines (containing killed virus) that are given with a needle. The regular seasonal flu shot is “intramuscular” which means it is injected into muscle (usually in the upper arm). It has been used for decades and is approved for use in people 6 months of age and older, including healthy people, people with chronic medical conditions and pregnant women..
About two weeks after vaccination, antibodies develop that protect against influenza virus infection. Flu vaccines will not protect against flu-like illnesses caused by non-influenza viruses.
The seasonal flu vaccine protects against the three influenza viruses that research suggests will be most common.
