‘No doubt there is a danger’ from ‘puffing, panting’ runners: Oxford professor LONDON: Joggers should wear face masks while exercising because running past people while breathing heavily could pose a coronavirus transmission risk, scientists have warned. “There is no doubt the virus is in the air, there is no doubt that you can catch it if you inhale, and that someone else has exhaled,” Prof. Trish Greenhalgh of the University of Oxford told TV program “Good Morning Britain.” She said: “The exercising jogger — the puffing and panting jogger — you can feel their breath come and you can sometimes actually feel yourself inhale it, so there’s no doubt that there is a danger there.” She added: “About 40 percent of coronavirus cases happen by catching it from people who have no symptoms. So you’re jogging along, you think you’re fine, and then the next day you develop symptoms, but you’ve actually breathed that coronavirus onto someone.” Devi Sridhar of the University of Edinburgh said: “This can spread through the air and so it is important that runners should think … I think we need some consideration for each other right now. We’re in a pandemic, so if you’re going to run or cycle in a busy area, wear a mask.” Former UK politician Tom Watson said: “If you’re a runner you should know obviously you’re breathing more deeply, and you should try not to run into people or run near them.”
