LOS ANGELES — With COVID-19, the flu and other respiratory diseases circulating widely in Los Angeles County and elsewhere, many officials are urging residents to use a familiar tool to help thwart transmission: masks.
But why should residents consider donning face coverings again, especially since mandates are no longer in place?
Health officials are largely united in noting that wearing a mask reduces the risk of viral transmission. There’s also a body of academic research supporting this.
