We're still in a pandemic – it isn't over for future variants, Omicron BA.2 is here, 30-50% more contagious than BA.1 (daily cases) – but catching COVID is not inevitable – you don’t have to become infected
Why should you wear a respirator?
Just as you wear sunscreen when it's sunny, and a raincoat when it's raining, likewise a mask can protect you from respiratory viruses
Using a respirator has reduced the risk of testing positive for COVID-19 by 83%
As such, it's worthwhile upgrading your mask to a respirator – besides better filtering:
- More comfortable, breathable, lightweight, fit better:
- Doesn't touch lips, easier and clearer to talk through
- Doesn't fog up glasses
Features of masks that will enhance comfort and fit
How the next pandemic surge will be different
The same: The brutal math of exponential growth. Different: Our pandemic fatigue is worse than ever.
What are common Long COVID symptoms?
