墨西哥推出鼻罩，网友：自欺欺人，你开心就好...
Researchers create nose-only COVID-19 masks to wear while eating

Researchers in Mexico have sniffed out a new COVID-19 mask designed for people to wear only over their noses while they eat.墨西哥研究人员发明了一种预防新冠的新型面罩，这种戴在鼻子上的面罩专为用餐中的人设计。

In the video, the pair takes off their normal masks to reveal their nose-only gear before chowing down at an outdoor table.视频显示，两人摘下了正常的口罩，露出了只遮住鼻子的鼻罩，随后在一张户外餐桌上大快朵颐。

Human cells that give people a sense of smell are a key entry point for coronavirus, making nose coverings important, according to Johns Hopkins University. But the World Health Organization recommends that people wear masks covering their nose, mouth and chin to best protect from the virus.

And Centers for Disease Control and Prevention studies have shown that more mask material is generally better than less. Last month, a CDC study showed that double-masking can significantly decrease the spread of the coronavirus.而美国疾控中心的研究表明，口罩用料多总比少好。上个月，疾控中心的一项研究表明，双重遮蔽可以显著减少新冠病毒的传播。
