Can I wear a face shield by itself?

Masks

A: NOPE. No face shield by itself. As we’ve previously covered, use of face shields by themselves is not recommended. A previous experimental study evaluated how well face shields protected the wearer, showing that smaller inbound particles can easily flow around the shield. Now in a new pre-print (not yet peer-reviewed) by scientists from the

Is it true that neck gaiters are *worse* than no mask at all?!

Masks Staying Safe

A: Probably not. If you like neck gaiters, breathe easy 🙂. Fabric (tighter weave) and fit are the more important variables, and wearing a face covering is almost certainly better than nothing at all. Double-up the layering to be safe. “Gaiter-gate” as it’s been lovingly dubbed, emerged last week from coverage of a small study

What to make of that recent study on different types of masks?

Masks Staying Safe

A: Check out this excellent post from our friend Your Local Epidemiologist! Types of face masks. In the past, we’ve only used surgical masks during epidemics (think SARS and MERS). We know these work. If you need the science (including a meta-analysis) let me know. But, now that we need masks on a global scale,

Do masks work at slowing the spread of Covid-19?

Masks Staying Safe

A: YES! Wearing a mask reduces the spread of droplets containing the SARS-CoV-2 virus. Blocking these droplets with a mask from shooting out into the world around us reduces transmission from person to person. Masks block a significant amount of these droplets while still allowing gases to pass in and out of the mask. Still

What’s the importance of ventilation in preventing SARS-CoV-2?

Infection and Spread Masks Reopening School Staying Safe

Q: How can I best manage the ventilation in my own office/school/home? A: Scientists are calling for more attention to VENTILATION in prevention of SARS-CoV-2 transmission. You can help manage risk by opening doors and windows where possible, increasing outside airflow and filtration in HVAC systems, using portable HEPA air filters, and wearing masks indoors.
