Influenza (often called “flu”) is a contagious illness caused by the influenza virus.  Symptoms include fever, cough, muscle aches, headache, runny nose, sore throat and general weakness.  The onset of these symptoms may be sudden.  Symptoms can range from mild to severe. Young children, people who are 65 years old and older, and people with other medical problems are at higher risk to develop severe illness if they get the flu.

Who should get vaccinated? Why? And, is it really at no cost?
 
Everyone six months and older should get the flu vaccine. Some people have a higher risk for serious illness, including young children, pregnant women, people who are 65 years old or orlder and people with certain health conditions (such as asthma, diabetes, heart disease, or other conditions). Even people who are not at risk for severe illness can pass the infection to their families, friends and patients, some of whom may fall into the high risk category. Getting the flu vaccines provides individual as well as community protection against the flu and is a public health step we can all take!

In addition to getting your flu vaccine, there are many ways you can help prevent the spread of germs, including:
  • ​Cover your mouth and nose with a tissue when you cough or sneeze. If you don't have a tissue, cough or sneeze into your upper sleeve.
  • Wash your hands often with soap and water or use an alcohol-based hand gel.
  • Keep your hands away from your eyes, nose, and mouth.
  • Clean surfaces in your home regularly with a household cleaner.
  • Avoid close contact with people who are sick when possible.
  • If you become sick, stay home. A person with the flu should stay home for 24 hours after their fever has gone away without the use of fever reducing medicine. For most people, this will be a minimum of 4 days.
