The World Health Organization (WHO) on Friday, 5 June, updated its guidance on the use of masks for control of COVID-19, advising all people aged 60 years or over, or those with underlying conditions, to wear a medical mask in situations where physical distancing is not possible.
The new guidance advises medical masks for all people working in clinical areas of a health facility in areas with widespread transmission, not only workers dealing with COVID-19 patients, Xinhua reported.
