The German news blog Freie Welt on April 7 carried an interview with a doctor at Korea University Guro Hospital in the article "Professor Kim Woo-joo from South Korea: Wearing protective masks contributed to the success of virus control in Asia." Kim said even conventional masks can dramatically reduce the risk of COVID-19 infection.
Though the U.S., Europe and the World Health Organization say wearing masks is not important, the doctor said Asia is aware of the importance of mask wearing through the MERS epidemic of 2015, adding that Korea and China have controlled COVID-19 through the widespread use of protective masks.
