Number (percentage) of first ascertained SARS-CoV-2 associated hospital admissions by type for each variant wave
| Variant period | ||||
|---|---|---|---|---|
| Original: 1 Jul 2020-5 Dec 2020 | Alpha: 3 Jan 2021-1 May 2021 | Delta: 30 May 2021-11 Dec 2021 | Omicron: 26 Dec 2021-17 Feb 2022 | |
| No of first ascertained infections | 127 210 | 158 960 | 1 612 630 | 1 014 855 |
| Covid-19 hospital related admission types | ||||
| All types of hospital admissions combined | 2445 (1.9) | 3300 (2.1) | 11 185 (0.7) | 9240 (0.9) |
| Specific types: | ||||
| Type A (due to or suspected to be due to SARS-CoV-2) | 1120 (0.9) | 1525 (1.0) | 5910 (0.4) | 5150 (0.5) |

| ICU or HDU care | 170 (0.1) | 325 (0.2) | 675 (0.0) | 335 (0.0) |
HDU=high dependency unit; ICU=intensive care unit.
Data for the periods when variants overlapped are not shown. The rate of SARS-CoV-2 associated hospital admission during each wave is calculated as the percentage of first infections starting in each period.
