The World Health Organization (WHO), which was passive in wearing masks for the public, belatedly changed its position and recommended wearing masks.

"The government should encourage the general public to wear a mask in places where it is difficult to keep the streets, such as public transportation and shops," said Governor Yeosu WHO, in a briefing last night (5th).

In the meantime, WHO has argued that there is no evidence that wearing a mask is useful to prevent the spread of corona19, but that it has updated its guidelines for using the mask through several reviews and consultations.
