UK study finds 'no evidence' of omicron having lower severity than delta

The omicron variant of COVID-19 shows no signs of being less severe than the delta variant, according to a new study in the United Kingdom.

Researchers with Imperial College London, who analyzed PCR test-confirmed COVID-19 cases in England between Nov. 29 and Dec. 11, said their endeavor found “no evidence of Omicron having lower severity than Delta,” judged by looking at “either the proportion of people testing positive who report symptoms, or by the proportion of cases seeking hospital care after infection.”
