Not wearing face-covering dramatically increases the risk of catching Covid-19, according to research led by a Texas A&M University professor. This has special significance as countries emerge from the drastic lock-downs imposed in the early stages of the pandemic, if a more serious second peak is to be avoided.
The team, which included Nobel Laureate Professor Mario Molina of University of California San Diego, found that face covering reduced the number of infections by 78,000 in Italy and by 66,000 in New York, according to a paper by Renyi Zhang, Texas A&M Distinguished Professor of Atmospheric Sciences and the Harold J. Haynes Chair in the College of Geosciences, and colleagues from the University of Texas, the University of California-San Diego and the California Institute of Technology.
