With Los Angeles County health officials announcing last month that masks will no longer be required indoors, a letter surfaced signed by doctors and researchers from the University of Southern California (USC) and the University of California–Los Angeles (UCLA) suggesting that mask mandates were ineffective at preventing the spread of COVID-19 in the county.
The February letter from researchers and medical professionals at UCLA’s David Geffen School of Medicine and USC’s Keck School of Medicine was sent to the Los Angeles County Board of Supervisors asking the board to end mask mandates.
