Influenza, also known as the flu, is a contagious respiratory disease caused by different strains of viruses. In the United States, there is a flu season that begins every fall and ends every spring. The type of flu people get during this season is called seasonal flu. Flu viruses spread from person to person when people who are infected cough or sneeze. Adults may be able to infect others 1 day before getting symptoms and as long as 5 days after getting sick.
The strain that is affecting thousands this year is similar to the H1N1 virus strain and is causing thousands to be hospitalized across the country. The best way to prevent the flu is by getting a flu vaccination each year and practice good hygiene skills.
Common Flu Symptoms

- Severe body aches
- Extreme tiredness
- Sore throat

- Vomiting and/or diarrhea (more common in children than in adults)
NOTE: Having all of these symptoms doesn’t always mean that you have the flu. Many different illnesses have similar symptoms.
