Government data shows masks had no impact on COVID spread

Cases rose and fell while mask-wearing remained constant

A graph that overlays data from surveys on mask usage with the number of coronavirus cases confirms studies that indicate the face coverings have no significant impact on the spread of the coronavirus.

Another chart, from a Financial Times analysis of the Covid Tracking Project, shows very little difference in the number cases between North Dakota and South Dakota. That’s despite the fact that North Dakota has had a mask mandate, while South Dakota has not.
