ATLANTA - While several studies already show that face masks and respirators effectively filter virus-sized particles and help reduce the spread of COVID-19 transmission, yet, another study is backing this evidence up.
According to a study, published by the Centers for Disease Control and Prevention last week, consistent use of a face mask or respirator in indoor public settings was associated with lower odds of a positive COVID-19 test.
The study enrolled randomly selected California residents who had received a test result for COVID-19 between Feb. 18, 2021 and Dec.
1, 2021. Face mask or respirator use was assessed among 652 participants who had received a positive test result for COVID-19, and 1,176 participants who had received a negative test result but reported being in indoor public settings during the two weeks preceding testing and who reported no known contact with anyone with confirmed or suspected SARS-CoV-2 infection during the time.
