Странно как то.
CDC говорит народу не рекомендовано носить маски.
А потом говорит медицинским работникам, что на очень крайний могут использовать банданы или шарфы хоть свойства из не очень изучены.....
In the recently updated guidelines for dealing with mask shortages, the CDC recommends that medical professionals "might use homemade masks (e.g., bandana, scarf) for care of patients with COVID-19 as a last resort" if other equipment is not available.
The recommendation is "alarming" to medical professionals because there's no evidence homemade masks can protect against the virus, according to Celine Gounder, epidemiologist and clinical assistant professor of medicine and infectious diseases at New York University.
"While wearing a scarf or bandana might help prevent a sick person from transmitting coronavirus infection to others by trapping respiratory droplets, it is unsafe for healthcare workers to rely on scarves and bandanas to protect themselves against infection by their patients," Gounder told Business Insider via email.
The CDC's own guidelines acknowledge that a bandana or scarf tied around the face still isn't considered personal protective equipment, noting that "their capability to protect [healthcare professionals] is unknown. Caution should be exercised when considering this option." The site also advises that workers should "ideally" use a full face shield in combination with a homemade mask.

При этом в азии всем советуют, это не только предложит хотя бы какой то минимум защиты, но поможет остановить цепочку заражений, учитывая что с ковидом симптомы частов малозаметны в начале но человек все равно может заразить.
But, David Hui, a respiratory medicine expert at the Chinese University of Hong Kong who studied the 2002 to 2003 outbreak of severe acute respiratory syndrome (SARS) extensively, says it’s “common sense” that wearing a mask would protect against infectious diseases like COVID-19.
“If you are standing in front of someone who is sick, the mask will give some protection,” Hui says. “The mask provides a barrier from respiratory droplets, which is predominantly how the virus spreads.”
He also says that the role of a face mask may be especially important in the epidemic due to the nature of the virus. Patients with COVID-19 often have mild or even no symptoms, and some researchers believe it can also be transmitted when patients are asymptomatic—meaning patients can be contagious and don’t know they’re sick.
Hui adds that the lack of solid evidence supporting the effectiveness of masks against the virus is no reason to dismiss its use, because there may never be definitive scientific proof. A properly controlled study would be impossible to conduct ethically, he explains. “You can’t randomize people to not wear a mask, and some to wear a mask, and then expose them all to the virus,” he says.

Проблема серьёзная, проблему надо хладнокровно и грамотно решать, а не верещать на каждом углу "мы все умрём".
А какое у вас хладнокровное решение проблемы?
