NBC晚间新闻 CDC建议人们戴口罩

Tonight with COVID-19 cases on the rise, the CDC now shifting¹ guidelines², calling on everyone to consider covering up. The CDC is advising the use of non-medical cloth face covering as an additional³ voluntary public health measure. So this is voluntary, I don't think I'm gonna be doing it. The voluntary measure turned from early March when masks were only recommended for the sick or immuno compromised⁴. The average American does not need to go out and buy a mask. The new guidance stemming⁵ from recent studies showing people without symptoms play a bigger role in spreading COVID-19. New York and LA, the first to issue citywide guidelines last week. We are afraid for our patients. With doctors still fighting to find medical grade N-95 masks, officials are urging people to use non-surgical options.

If you can't buy a mask of your own, the CDC says something as simple as a t-shirt or even a bandana can still work. A couple quick folds towards the middle adds a layer of protection. Then slip a rubber band around each end. Fold again and you're set. Even if you don't have any symptoms wearing this. Then keep others safe. Nationwide the homemade mask effort has already taken off. In North Carolina police are putting their sewing skills to the test to make sure officers are safer when on patrol⁶. We should be, first of all, staying at home and practicing social distancing. And then on top of that if you need to leave you absolutely should wear a non medical grade mask. The newest step of many in the fight against an invisible⁷ enemy.
