Dr Meng Khaw, National Director for Health Protection and Screening Services for Public Health Wales, said:
“Public Health Wales is today (Wednesday 15 December) confirming 30 new cases of Omicron variant in Wales, bringing us to a total of 62 cases.
“Part of the increase today is linked to a change in case definition agreed across the UK, as cases previously identified as highly probable are now classed as confirmed by genotyping. However, as we have indicated previously, a rapid increase over the coming days and weeks is expected.”
The breakdown of Omicron cases by health board area is as follows:
| Health Board | Total cases |
| Cardiff and Vale University Health Board | 23 (+9) |
| Betsi Cadwaladr University Health Board | 10 (+5) |
| Cwm Taf Morgannwg University Health Board | 6 (+1) |
| Aneurin Bevan University Health Board | 9 (+5) |
| Swansea Bay University Health Board | 9 (+7) |
| Hywel Dda University Health Board | 3 (+2) |
| Powys Teaching Health Board | 2 (+1) |
| Total | 62 (+30) |
