Scores of people have turned up at a pilot scheme of mass coronavirus testing in Merthyr Tydfil, South Wales. Rapid Covid-19 tests are being offered to the area’s residents and workers even if they do not have coronavirus symptoms, a week after the town registered the highest rate of new cases in the UK. Merthyr Tydfil has since seen the biggest drop in cases in Wales from around 770 per 100,000 to below 260, as the effect of the country’s 17-day firebreak begins to show. Testing began on Saturday morning at the town’s Rhydycar Leisure Centre, with more sites due to open through Merthyr Tydfil County Borough this month.
