Fast Company reports that while it’s too soon to tell how severe the 2019-2020 flu season will be, there are tools available that can help keep track of the flu as it spreads across the country.

Health officials in the United States have already reported three deaths due to the flu.

Early tracking of flu cases is key to containing outbreaks, and Walgreens has a tool that helps you do just that. The pharmacy chain has just released its first monthly flu index along with an interactive map that shows which areas of the country are being hardest hit.

According to the data, October saw increased activity across parts of the South when compared to the same period last year.
