The World Health Organization (WHO) changed its advice on face masks, saying MASKS SHOULD BE WORN where COVID-19 is widespread."In light of evolving evidence, WHO advises that governments should encourage the general public to wear masks where there is widespread transmission and physical distancing is difficult," WHO’s Director Tedros Adhanom Ghebreyesus said on Friday, June 5th. The WHO had previously advised that only people who were ill, or caring for someone who was ill, should wear masks.
Many retailers, transit systems, and municipalities had previously deemed face masks mandatory in public areas.
