Good news about masks (observational)

The masks must be working! I attended morning mass at St. Andrew this morning. About 60 people--all but a few around my age. No coughing, throat clearing, nose blowing, gagging or sniffling, and you know how congested old people always are, especially in the morning--and the architecture of the sanctuary encourages echoes. It was heavenly (although I realize heaven is filled with praises to God and may be noisy). I think the masks are cutting back on those other coronaviruses, respiratory syncytial (sin-SISH-uhl) viruses and rhinoviruses--the ones that cause common colds. So let's hope they can block SARS-CoV-2, the coronavirus causing Covid19.
