On Tuesday, the World Health Organisation (WHO) revised its stand on masks, acknowledging that wearing a medical mask is one of the prevention measures that can limit the spread of certain respiratory viral diseases, including Covid-19. Even before WHO's advisory, Health Cabinet Secretary had called on Kenyans to start wearing masks outdoors to stop the spread of the disease. Dr Patrick Oyaro, an epidemiologist and a public health expert, explained how face masks prevent diseases. He told the Nation that masks are “a physical barrier” which catch tiny organisms (microbes) that the sick person may expel to the environment. Kenyatta National Hospital’s Elly Nyaim warned the wearer not to touch the outer front part of the masks.
