Seven types of face masks were put to the test by the University of Edinburgh, including surgical masks, respirators, lightweight and heavy-duty face shields, and homemade face coverings. As the breath could contain small droplets of water, some of which may contain traces of the virus, experts have said wearing any type of face covering could be crucial in tackling Covid-19. Dr Felicity Mehendale, a surgeon at the Centre for Global Health at the University of Edinburgh’s Usher Institute, said: “It was reassuring to see the handmade mask worked just as well as the surgical mask to stop the wearer’s breath flowing directly forwards. “However, we discovered that some face coverings allow the emergence of downward or backward jets that people are not aware of and that could be a major hazard to others around them.” Dr Mehendale added: “The strong backward jets mean you need to think twice before turning your head if you cough while wearing a mask and be careful if you stand behind or beside someone wearing a mask.” The University of Edinburgh says its findings could help steer official guidance on wearing masks to help tackle coronavirus.
