The World Health Organization (WHO) on Friday broadened its recommendations for the use of masks during the coronavirus pandemic.

It is now advising that in areas where the virus is spreading people should wear fabric masks when social distancing is not possible, such as on public transport and in shops.

WHO Director-General Tedros Adhanom Ghebreyesus said people over age 60 or with underlying medical conditions also should wear masks in situations where social distancing cannot be maintained.

WHO previously had recommended that only health care workers, people with COVID-19 and their caregivers wear medical masks, noting a global shortage of supplies.
