Wearing masks or not: WHO and CDC cannot come to a consensus

The World Health Organization (WHO) recommends that healthy people, including those who do not have COVID-19 symptoms, wear masks only if they care for someone infected with coronavirus. This contrasts sharply with the recommendations of US officials recommending everyone wear masks outside the home. Writes about it Fox News.

“If you don't have respiratory symptoms such as fever, cough or runny nose, you don't need to wear a mask,” says Dr. April Baller, a public health specialist at WHO. “Masks should only be used by health care workers, caregivers, or people who are sick.”

WHO recommendations differ from those of the Centers for Disease Control and Prevention (CDC), which strongly recommend that absolutely everyone wear a protective mask in public places, whether or not they are infected, to limit the spread of the virus.

“It is now known from recent studies that a significant proportion of people infected with coronavirus do not have characteristic symptoms. And at this stage, the virus is able to be transmitted to others, the CDC said. “We therefore recommend wearing masks in public places where social distancing measures are difficult to maintain.”

Balller noted that masks can give people a “false sense of protection,” and patients should wear them to prevent transmission of the virus to others.

Here's how to make a mask yourself.
