WASHINGTON - Health experts have determined that face coverings are a vital tool in reducing the spread of coronavirus - but little research has been done into how different kinds of masks compare.
"We need to scale up surgical mask production and distribution," tweeted Dr Tom Frieden, the former director of the Centres of Disease Control and Prevention under then president Barack Obama, in response to the study that appeared in Science Advances. A computer algorithm was then used to calculate the number of droplets. The laser and lens involved can be bought for US$200 and the experimental design is easy to replicate by non-experts.
Surgical or polypropylene masks were not far behind, bringing droplet transmission down by 90 percent or more compared to no face-coverings.
