The UK is experiencing an increase in COVID-19 cases driven by the highly transmissible Omicron variant, with record daily infections of 189,846 reported on Friday.

While hospital admissions have begun to rise, the government has said it believes the new variant is milder than the Delta variant.

Susan Hopkins, Chief Medical Adviser at UKHSA, said the analysis was in line with other encouraging signs on Omicron, but said healthcare could still struggle with such high transmission rates.

“It is still too early to draw any definitive conclusions about the severity of the hospital’s, and the increased portability of Omicron and the growing number of people over the age of 60 in the UK mean that there is still a high probability that there will be significant pressure on NHS in the coming weeks. ” she said.

Friday’s daily data update showed 12,395 patients in hospital in the UK with COVID-19, up from 11,542 on Thursday and continuing a steeply rising trend. However, the figure is well below a peak of more than 34,000 in January.
