Mask mandate appears to be helping in Texas, but experts ask Gov. Greg Abbott not to rule out a shutdown

Three weeks after Gov. Greg Abbott required Texans to wear masks, epidemiologists and disease modelers say they are cautiously optimistic that the mandate is helping the state turn a corner in its efforts to contain an outbreak that has killed more than 4,500 Texans.

Throughout the summer, Texas’ coronavirus outbreak became grimmer by the day and by almost every metric: case counts, hospitalizations, deaths. But in the past week or so, Abbott and some of the state’s public health officials began to see hope in the daily case counts as they appeared to stabilize.

A growing body of evidence points to widespread mask-wearing as an effective strategy for containing the virus, and one North Texas researcher’s statistical analysis published this week argued that local mask orders in the region reduced viral transmission enough to avoid a lockdown. The governor, who has faced blistering criticism for his handling of the pandemic from members of his own political party, immediately seized upon those findings in defense of his statewide order.

“A community lock down is not needed as long as masks & other distancing strategies are used,” Abbott wrote Monday on Twitter, citing the analysis by Rajesh Nandy, a professor of biostatistics and epidemiology at the University of North Texas Health Science Center.
