I’ve been following this issue as well. Last week, in an open letter, more than 200 scientists called on the World Health Organization to acknowledge that COVID-19 can be spread in smaller, microscopic particles in the air and not just through large respiratory droplets, as the WHO asserts.
If the novel coronavirus can be spread in the air, then social distancing and hand washing will not be as effective in slowing the spread. The authors recommend “airborne infection controls such as local exhaust, high efficiency air filtration, and germicidal ultraviolet lights” and increased ventilation.
“Hand washing and social distancing are appropriate, but in our view, insufficient to provide protection from virus-carrying respiratory microdroplets released into the air by infected people,” the letter states.
