Navigating flu season

October 29, 2020

During the fall and winter months, as we begin to bundle up for the cold weather, we must also remember it’s time to protect ourselves during flu season. Influenza, commonly referred to as the flu, is typically characterized by the onset of fever or feeling feverish/chills, aching muscles, sore throat, and a cough.

By taking preventative measures, such as vaccination, members of the PI community can have a decreased chance of being exposed. Listen as we discuss navigating flu season with PJ Maglione, MD.
