It’s becoming clearer and clearer that the countries where people have been wearing masks outside are doing a much better job flattening the curve than the rest of the world. These tend to include Far East countries where people have been wearing them since the first SARS outbreak in 2002 such as Taiwan and South Korea, but here’s a video from the Czech Republic that makes the point very persuasively. I hope everyone will share this on social media and other methods of communication (e.g., emails to loved ones).
For more on why you need to wear a mask, I recommend this Washington Post article.
