Quit Buying Coronavirus Masks You Don't Need
疫情当前,不需要口罩的你请别再买啦
When a disease outbreak is ongoing, there are important things that uninfected people need to know and do, like washing hands. There are also things not to do, because they are mostly useless and actually interfere with people who need them. For most of us, face masks fall into the second category.
疾病爆发时,未感染者需要了解一些重要事项,包括洗手。当然,有些事是不需要做的,因为这些事不仅没用,还会影响真正需要他们的人。对于大多数人而言,口罩属于第二类。
As we discussed earlier, surgical masks can help you stop spreading your germs to someone else, but they're of limited usefulness in protecting you from coronavirus in the outside world. Respirator masks are a bit more effective, but unless you're in a hospital or in a high risk area (like Wuhan) they're overkill.
我们之前讨论过,外科医用口罩可防止将细菌传播给他人,但在防护新型冠状病毒方面,它们的作用有限。N95口罩的效果更佳,但除非住院或身处高风险地区(如武汉),否则佩戴此类口罩实属浪费。
So what’s the harm? If supplies were unlimited, there wouldn't be any. But there are only so many face masks manufactured every year, and a lot of them are actually made in China. As Maryn McKenna writes here, China is choosing not to export as many of their masks and other personal protective equipment, because they need them at home.
