Flu is a contagious respiratory illness caused by influenza viruses. Flu can be contracted by inhaling respiratory droplets produced an infected person's coughing or sneezing, or by touching a surface contaminated by the virus and then touching your own mouth, nose, or eyes. If someone has the flu, he or she is contagious from the day before the onset of symptoms up to seven days after getting sick. If you’d like to learn more, the Centers for Disease Control and Prevention (CDC) is an excellent source of information about the flu.

You can come into any Patient First center from 8am to 10pm any day of the week - no appointment needed.
