(Reuters) - The chances of transmission of COVID-19 during professional sports events are very low, a British doctor researching the impact of the disease told Reuters on Friday.Chris Orton, a research fellow at London’s Chelsea and Westminster hospital, said there have been no confirmed cases of COVID-19 transmission in the United Kingdom during a training session or live match. The FA could not immediately be reached for comment. Orton’s comments come on the same day Ireland midfielder Alan Browne tested positive for the novel coronavirus, less than 24 hours after playing against England in Thursday’s friendly at Wembley Stadium.
