Face masks must cover both mouth and nose

Editor, Times-Dispatch:

In an effort to encourage individuals to wear face masks during the current pandemic, numerous references have compared their use to that of seat belts — a simple device that can save lives. Yet, despite their simplicity, these devices only work when properly worn. While some might claim that wearing a seat belt shoulder harness across the chest is uncomfortable, the alternative of wearing the harness behind one’s back doesn’t allow it to work as intended. Likewise, while wearing a face mask might be uncomfortable, especially during hot weather, to be effective, it must cover both your mouth and your nose.
