Mask wearing in public is considered essential to reduce the spread of the coronavirus. It is assumed that wearing masks reduces the likelihood of an infected person spreading the virus, and the likelihood of a properly masked person inhaling droplets containing the virus. In a study published in the ‘Science Advances Journal’ on Friday, health experts tested 14 commonly available masks. Some homemade cotton masks also proved to be fairly effective in controlling the transmission of droplets. Managing director Bernard Njiraini said an effective mask must factor in the filtration capacity, efficiency of the material, capacity to absorb moisture and the fit of the mask to the wearer’s face.
