May 27, 2020 -- Something has been bothering Kimberly Prather, PhD: Everything she reads about COVID-19 points to a pathogen that travels through the air.
“It’s just shocking to me, quite honestly, that this has not been factored in.”
And she believes masks can play a major role in stopping that transmission.
在接受美国magazine on May 26, Anthony Fauci, MD, who leads the National Institute of Allergy and Infectious Diseases,在教堂中引用气溶胶传输.
“When you sing, the amount of droplets and aerosol that come out is really, in some respects, scary,” Fauci said.
In aperspective articlefor the journal科学，普拉瑟明确勾画出空气传播的证据，并解释了什么人需要做什么来保护自己。它迅速在社交媒体上回升。
科学已经成为自那以后要先进得多。普拉瑟和其他人开发的仪器，可以“看到”非常微小的粒子 - 气溶胶。气溶胶以微米测量，或一米的百万分之一。一个人类红血球的大小大约为5微米。这些粒子非常小，从咳嗽或打喷嚏时蒸发的水分，而他们仍然在空气中。他们漂浮在空气中的电流。他们花时间来解决。
“I have to say something because this could actually protect people,” she says. What airborne transmission means, she says, is that 6 feet is not far enough to stand apart. It also means we should probably be wearing masks a lot more often.
“It’s very fixable. Masks aren’t that big of a deal,” she says. “To me, I look at this as a solution.”
She points to the success Taiwan has had stopping the spread of the infection. Taiwan has only had a few hundred cases and only seven deaths, even though the country never implemented a national lockdown. Instead, they aggressively tested their citizens, quarantined people who tested positive for 2 weeks, and had everyone wear口罩.
“If you look at countries that just naturally wear masks when people feel sick … those countries did a lot better than those that did not,” Prather says.
She wears hers inside and outside, especially if she’s walking outdoors in a place where she can see other people. She tells people to imagine how far they can smell cigarette smoke or a barbecue. That’s how far aerosols can travel between you and another person.
这是原因之一，面罩 - 塑料覆盖人都穿着着他们的脸 - 不工作，不戴面具。面罩挡住飞沫，气溶胶，但仍然可以找到一种方式。
- A new normal consists of more handwashing, social distancing, and shielding older people and people medically vulnerable to the disease.
- Nursing homes are ground zero for the COVID pandemic and require policies to immediately isolate residents with symptoms and reduce visitors.
- More robust healthcare systems are needed to prepare for a surge, so hospitals don't become overwhelmed.
