A large study run in Bangladesh claimed that surgical masks, but not cloth masks, reduced symptomatic SARS-CoV-2 infections" by 0.08% (ARR), and only in people over 50. But a subsequent re-analysis of the study by statisticians found that there was in fact no benefit at all.

People with chronic respiratory, cardiac, or other medical conditions that make breathing difficult should check with their health care provider before using an N95 respirator because the N95 respirator can make it more difficult for the wearer to breathe.
