Czech Prime Minister Andrei Babich on Sunday advised US President Donald Trump to make putting respirators in public places mandatory to limit the recovery of the emerging corona virus.

"He tried to tackle the virus in the Czech way," he said in a tweet directing Babich to Trump.

Babich, like Trump, is a billionaire businessman who has become a populist politician.

And the Czech prime minister added that: "Putting any cloth mask reduces the spread of the virus by 80 percent!" "The Czech Republic forced its residents to put a muzzle in public places."

Babish asked the American president to "retweet," adding "God bless America!"

Babish has not attached his tweet to any scientific source supporting the theory that the muzzle reduces the risk of developing Covid-19 by 80 percent.

There is no consensus in the scientific community that placing people who are not infected with the virus as masks is an effective way to protect them from infection with Covid-19, and guidelines differ in this regard from one country to another.

Health authorities advise several residents not to buy gags because of a lack of stock.

According to the World Health Organization, only those who are infected with a virus are required to wear a muzzle.

In the United States, the Center for Disease Control and Prevention issued similar directives clarifying that those who must wear a muzzle are exclusively patients and those caring for a patient.

However, a study prepared by the center in 2009 states that "in certain cases it may be advised" to place masks in gatherings where the virus "AH 1N1", commonly known as "swine flu" is monitored.

In the Chinese city of Wuhan, where the first virus was detected in December, the authorities forced residents to place masks in public places, according to the official Pebbles Daily.

This March, the Babish government came under criticism for a severe shortage of masks, which prompted thousands of Czechs to sew special protective masks.

Since then Prague started importing medical supplies from China.

In addition to making the muzzle mandatory, the Czech Republic has closed its borders, schools, bars and most of its stores to reinforce efforts to cope with the outbreak.
