With the flu season not that far away, a new Centers for Disease Control & Prevention (CDC) page discusses the similarities and the differences between influenza (flu) and COVID-19 that may be of interest to health center staff and patients. Because some of the symptoms of flu and COVID-19 are similar, it may be difficult to tell the difference between them based on symptoms alone, and testing may be needed to help confirm a diagnosis. Flu and COVID-19 share many characteristics, but there are some key differences between the two. While more is learned every day and there is still a lot that is unknown about COVID-19 and the virus that causes it, the page offers the best available information to date.
