Omicron is milder than Delta UK study finds

Omicron appears to be a milder version of COVID-19 than the Delta variant, a leaked British government study shows.

The UK Health Security Agency, the US equivalent of the Centers for Disease Control, found that those who get sick with Omicron are less likely to become seriously ill compared to those who get the Delta variant, according to data obtained by Politico.

The first real-world data, expected to be released before Christmas, found that Omicron is likely to cause a mild illness with less severe symptoms in most people.

It is likely due to the large number of people who have been previously vaccinated and infected, plus Omicron is naturally milder than other variants of the coronavirus.

However, the UK health agency cautioned that the data showed that Omicron’s mildness was not enough to prevent large numbers of hospitalizations.
