To the editor:
The science of how COVID-19 spreads is now clear. Regardless of what you see on Facebook or elsewhere, folks like Dr. Fauci and other government and independent scientists agree that COVID-19 is mostly spread when we breathe, talk, sing, shout, cough or sneeze. In other words it is expelled from our mouths and noses human-to-human.
The coronavirus is too small to be seen and is contained in the tiny water droplets infected individuals exhale. The tiniest droplets hang in the air longer and travel further, up to 16 feet, carried on air currents. Clearly we are at greater risk of catching or spreading the virus in enclosed spaces and safer when outdoors or being indoors with mask-wearing, adequate distancing and good ventilation.
We have learned that in addition to high-risk individuals, people with no pre-existing conditions can become gravely ill. It is our obligation to protect both ourselves and others by social distancing, mask wearing and hand washing. Stay home for two weeks if you test positive whether or not you have symptoms. Do your duty.
