This is an article from the NY Times I thought was important to share. The advice from the CDC up until now has been to save the masks for the medical staff. Now, given that it is clear that most people are asymptomatic, everyone should wear some kind of mask.

While a mask without eye protection and strict adherence to handwashing (and no face-touching) does not offer maximal protection to the wearer, it does offer some. And it reduces the amount of virus you shed into the environment. It includes a link to a pattern for all you seamsters out there.

This is a link to the latest thinking about how the virus spreads.

Do not change your behavior to avoid being infected. Assume you are infected and change your behavior to avoid transmitting.


More Americans Should Probably Wear Masks for Protection

The Centers for Disease Control and Prevention is having second thoughts about masks.
For weeks, it (and we) said that ordinary citizens in the U.S. did not need to wear them unless they were sick and coughing or were caring for someone who was.
Now, with the number of cases in the U.S. doubling every three or four days, it looks as though that may not have been the best advice.
New data cited by Dr. Robert Redfield, the director of the C.D.C., shows high rates of transmission by people who are infected but don’t know it yet. An infected person can be contagious for 48 hours before developing symptoms, if they get them at all. Having a mask on could cut down on the number of transmissions from asymptomatic people.
So the C.D.C. is now considering whether to recommend that more people — maybe everybody — wear a mask when out in public.
Not a high-grade N95 medical mask, though. Those are scarce and should still be saved for those who need them most, medical professionals and others on the front lines. One reason the C.D.C. hesitated to advise universal mask-wearing was to avoid making shortages of those masks even worse.
But for this purpose, you don’t need that type; ordinary surgical masks and even homemade masks will do. They will help slow transmission in the community, even though they don’t ensure complete protection for the wearer.
And there’s a side benefit: Wearing any kind of mask, even a bandanna, will make you less likely to touch your face — an important route for infection.
Make your own mask. It isn’t difficult, and you may already have everything you need at home. Here’s a guide.
