Harvey V. Fineberg, a noted researcher in the fields of health policy and medical decision making,
writes to Kelvin Droegemeier, who is currently serving as the Director of the Office of Science and Technology Policy and Acting Director of the National Science Foundation,
On the possibility of airborne, respiratory transmission of SARS-CoV-2:
(i.e. passive through talking, breathing, etc. aerosolized particles are emitted that linger in the air, rather than infection exclusively through heavy “droplets” from coughs or sneezes)

Facial Coverings:
CDC warns of asymptomatic transmission, recommends everyone wears cloth face coverings in public:

Visualization of a person breathing, talking, and coughing with and without a face covering:
What’s happening on Twitter:
Masks and face coverings can help a bit, but really should be thought more as source control than personal protection equipment (PPE).
“My mask protects you, your mask protects me” is the new social contract
Social distancing should still be adhered to
The latest science explained:
Source control: my mask protects you, your mask protects me
Still need to social distance (6ft.) though
And now: The viral social media meme:
- Correlation does not prove causation, but it can give us a wink and a nudge.
- To be fair, these four countries have also undertaken different types of disease control to western countries in other ways (e.g. S Korea, Singapore with aggressive early response and lockdowns)
- And, it’s thought that even if masks help, it would mostly be to protect others from yourself. Social distancing (6ft) still matters, and I would wager that even then it’s probably not a guarantee.
