You may be right. South Korea has done 503k tests, ie 9800 tests per million of population
UK has done 316K tests, 4617 tests per million of population.

More concerning to me is that today UK states 5,100 new cases, 315 in Wales

Public health Wales says 503 new cases, and Public Health England says over 8,000 for England giving a UK total a little under 9,000
