Note: This information is about face coverings worn to prevent infecting others, sometimes known as "source control" measures. See the PPE topic below for info about masks to protect the wearer.
Several recent publications indicating universal wearing of face masks, even homemade masks and simple cloth coverings, can prevent spread of the pandemic.
Health Affairs: JUNE 16, 2020 Community Use Of Face Masks And COVID-19: Evidence From A Natural Experiment Of State Mandates In The US
Proceedings of the National Academy of Sciences (PNAS): June 11, 2020: Identifying airborne transmission as the dominant route for the spread of COVID-19
Our analysis reveals that the difference with and without mandated face covering represents the determinant in shaping the trends of the pandemic. This protective measure significantly reduces the number of infections. Other mitigation measures, such as social distancing implemented in the United States, are insufficient by themselves in protecting the public.
Proceedings of the Royal Society A 10 June 2020: A modelling framework to assess the likely effectiveness of facemasks in combination with ‘lock-down’ in managing the COVID-19 pandemic
We show that, when facemasks are used by the public all the time (not just from when symptoms first appear), the effective reproduction number, , can be decreased below 1, leading to the mitigation of epidemic spread. Under certain conditions, when lock-down periods are implemented in combination with 100% facemask use, there is vastly less disease spread, secondary and tertiary waves are flattened and the epidemic is brought under control. The effect occurs even when it is assumed that facemasks are only 50% effective at capturing exhaled virus inoculum with an equal or lower efficiency on inhalation.
IZA – Institute of Labor Economics JUNE 2020: Face Masks Considerably Reduce COVID-19 Cases in Germany: A Synthetic Control Method Approach
early introduction of face masks in Jena has resulted in a reduction of almost 25% in the cumulative number of reported Covid-19 cases after 20 days. The drop is greatest, larger than 50%, for the age group 60 years and above. ... After the introduction of the mandatory masks, "the number of new infections fell almost to zero"

2020-04-06 Lockdown Can’t Last Forever. Here’s How to Lift It By Gabriel Leung
Please consider participating in the Stanford Medicine National Daily Health Survey. The goal is to learn and predict which geographical areas will be most impacted by coronavirus. It takes a minute or two the first day and just seconds on following days.
The disease: COVID-19 - coronavirus disease.
The virus: SARS-CoV-2 - severe acute respiratory syndrome coronavirus 2.
See "Impact of non-pharmaceutical interventions (NPIs)..." and "The Hammer and the Dance" below for use of these terms.
containment: tracking the dissemination of a disease within a community, and then using isolation and individual quarantines to keep people who have been infected by or exposed to the disease from spreading it
mitigation: slowing but not necessarily stopping epidemic spread – reducing peak healthcare demand while protecting those most at risk of severe disease from infection... for example:
suppression: reversing epidemic growth, reducing case numbers to low levels and maintaining that situation indefinitely, for example:
anosmia: loss of sense of smell
ageusia: loss of sense of taste
NOTE: 2020-03-21 ENT UK: Loss of sense of smell as marker of COVID-19 infection (slow link)
there have been a rapidly growing number of reports of a significant increase in the number of patients presenting with anosmia in the absence of other symptoms
receiver protection: your mask protects you from others. A properly fitted N95 provides effective receiver protection, but fitting is very difficult and not easily achieved by members of the public without training and equipment.
source control: your mask protects others from you. A basic surgical-type face covering provides effective source control.
CDC recommends wearing cloth face coverings in public settings where other social distancing measures are difficult to maintain (e.g., grocery stores and pharmacies) especially in areas of significant community-based transmission.

These are up-to-date values for Rt, a key measure of how fast the virus is growing. It’s the average number of people who become infected by an infectious person. If Rt is above 1.0, the virus will spread quickly. When Rt is below 1.0, the virus will stop spreading.

It is a fundamental scientific error to take the current success of containment in some places as a sign that permanent containment is possible. We should work to make it possible, but 1918 flu and, frankly, the germ theory of disease show that containment is a temporary victory

I think most people aren’t aware of the risk of systemic healthcare failure due to #COVID19 because they simply haven’t run the numbers yet. Let’s talk math.
The amount of oxygen to it takes to keep a COVID-19 patient alive is absolutely startling... Apparently 8 or more of those massive oxygen cylinders/day to keep someone alive.

Here is how it looks in practice. Most of my childhood friends are now doctors working in north Italy. In Milan, in Bergamo, in Padua, they are having to choose between intubating a 40-year-old with two kids, a 40-year old who is fit and healthy with no co-morbidities, and a 60-year-old with high blood pressure, because they don't have enough beds. In the hallway, meanwhile, there are another 15 people waiting who are already hardly breathing and need oxygen.
