Only Merthyr Tydfil, which has consistently been the country’s coronavirus “hotspot”, recorded a higher rate of infection with 227.1.
Another key indicator of a particular county’s virus prevalence is the proportion of tests which are returned positive.
Here, Cardiff came out on top with more than one in 10 (13.2%) tests being positive, compared to 12.4% in Merthyr Tydfil, 11.1% in Rhondda Cynon Taf (RCT) and Flintshire and 10% in Bridgend which came in at second, third and fourth highest respectively.
Less than a month earlier, for the week September 14 to 20, Cardiff was recording 39.8 cases per 100,000 and a positivity rate 2.9%, which demonstrates just how quickly the virus is spreading.
The rise in cases is translating into hospital admissions with three Covid-19 patients now in ventilated intensive care beds in Cardiff and the Vale health board hospitals. There are also 85 confirmed, suspected and recovering Covid-19 patients in all Cardiff and Vale hospital beds as of October 13.
