GENEVA: The WHO said on Monday (Apr 6) that face masks could be justified in areas where hand-washing and physical distancing were difficult, as it teamed up with Lady Gaga to launch a giant coronavirus awareness concert.
World Health Organization chief Tedros Adhanom Ghebreyesus said masks alone though were no "silver bullet" to defeating the COVID-19 pandemic, which has killed more than 70,000 people.
