Leadership from the Shelby County Health Department is crediting the mask mandate for a reduction in the infection rate. Below is a clip from today’s Joint Covid Task Force news conference.
“There have been two time periods where we had… the reproductive rate pushed below one. The first was last July, after the initial face-masking orders went into place across the county and throughout the City of Memphis, and that – just simply wearing the mask – drove the reproductive rate of the virus down by interfering enough with the transmission of the virus that Rt (or reproductive rate) dropped below one.” – David Sweat
Unfortunately, there are a few problems with this interpretation.
