The epidemic of choranavirus, which first appeared in Wuhan, China, spread rapidly across the world, causing more than 37 thousand people to die. Due to the epidemic, many countries took different measures. Flights are stopped, big events and organizations are canceled, and people are called to stay at home to maintain social distance. Avoid wearing masks if you are not sick Stating that there is no evidence that the use of the mask is useful, WHO Emergency Aid Director Micheal Ryan noted that the mask could be infected by removing the mask incorrectly, thereby creating additional risks. “So our advice is to avoid using a mask if you’re not sick yourself,” said Ryan. The use of a mask against coronavirus is among the controversial topics. While the Czechia made it mandatory to use masks in public places, Austria announced that it would be necessary to wear a mask during supermarket shopping.
