However, to start out with, a small historical past: On its website, the Mayo Clinic responses the query: “How correctly do facemasks safe versus COVID-19?” The clinic states:
“The [Centers for Disease Control and Prevention] states that you simply actually ought to have on essentially the most protecting masks achievable that you simply’ll use regularly and that matches.
