Mask mandates reduced COVID-19 in two-thirds of States
A new analysis from Texas Tech University’s Department of Environmental Toxicology suggests how much of a difference face coverings have made.
The U.S. Centers for Disease Control and
Prevention have recommended face masks to protect against COVID-19 practically
since the pandemic began, and still the debate about their efficacy endures.
But a new analysis from Texas Tech University’s Department of Environmental
Toxicology suggests how much of a difference those face coverings have made.
Published Thursday (April 1) in the
International Journal of Environmental Research and Public Health, the research
analysis by doctoral student James Ayodeji and his adviser Seshadri Ramkumar,
professor of chemical countermeasures and advanced materials, shows that
roughly two-thirds of states saw a reduction in COVID-19 cases in the three to
four weeks after enacting a mask mandate.
The researchers examined confirmed cases of
COVID-19 from April 1-Dec. 31, 2020, for U.S. states with and without mask
mandates. They analyzed the daily numbers of new cases, cumulative confirmed
cases and infection rates per 100,000 people. After extrapolating data trends
from the 10-20 days before each state’s mask mandate was enacted, the pair
projected the number of cases that would have been confirmed at 21 and 28 days
after the mandate, had the trend continued. Then, by subtracting the actual
numbers of cases on those days from their projections, they determined an
approximate number of cases the mask mandates helped to prevent in each state.
They determined that 63 per cent of the
states saw a reduction in daily and cumulative cases 21 days after the mandates
began, and 66 per cent saw a reduction after 28 days. New York, Iowa and
Massachusetts showed the greatest reductions after their mask mandates went
into effect. New York’s actual number was 111,417 cases lower than its
projection after 21 days, and 160,956 lower than projected after 28 days.
Iowa’s actual case numbers were 49,750 and 69,448 lower, respectively, and
Massachusetts’ 23,816 and 35,104 lower.
Of course, not all states saw such success.
California’s number of actual cases were 74,276 higher than projected 21 days
after its mandate was enacted, and 114,937 higher at 28 days. Michigan’s case
numbers were 29,743 and 64,892 higher than projected, respectively. Texas’ case
count was 35,026 higher than projected at 21 days and 41,723 higher at 28 days.
The data shows the potential difference
face coverings can make, the authors noted, but only if mask mandates are
adhered to and masks are worn properly. If not, users will touch the face more
frequently to adjust the fit of the mask, which can increase the likelihood of
transmission. The communal use of face coverings in conjunction with other
mitigating measures provides maximum protection, they emphasized.
“Being a material scientist, I never
thought that a material made from cotton and its blends – a face mask – would
have so much global impact in saving lives,†Ramkumar said. “It makes it clear
that to solve global problems, multidisciplinary research is the need of the
hour.â€
