Preliminary data has suggested that people infected with the Omicron variant are 50 to 70% less likely to be hospitalised than those with the delta strain.
This data comes from Britain’s public health agency and was announced last Thursday in a finding that one researcher has called a ‘small ray of sunlight.’ The findings add to emerging evidence that Omicron produces milder illness than the other variants of COVID-19.
Scientists still however caution that any reduction in severity must be weighed against the fact that Omicron spreads much faster than Delta and is better at evading vaccination immunity.
This is based on cases in the UK, where a person with the variant is estimated to be 31% to 45% less likely to go to hospital or the emergency department compared with someone with delta.
The analysis is still preliminary and uncertain because of the small number of omicron patients in hospitals and because of the fact that most were in younger age groups. As of the 20th of December, 132 people were admitted to UK hospitals with confirmed Omicron cases. Fourteen of them died, all aged 52 to 96.
