An evaluation of the asymptomatic testing pilot in Merthyr Tydfil and Lower Cynon late last year by Cwm Taf Morgannwg Health Board found testing was very cost effective and had contributed to the subsequent decline in coronavirus case rates. It found an estimated 353 cases, 24 hospitalisations, 5 Intensive Care Unit admissions and 14 deaths, that would have otherwise occurred, were prevented.
