Covid is less severe with Omicron than Delta, US study suggests

The findings were consistent with previous data analyses from South Africa, England and Scotland, where infections from Omicron peaked earlier than in the United States, the CDC said.

The Omicron variant appears to result in less severe Covid-19 than seen during previous periods of high coronavirus transmission including the Delta wave, with shorter hospital stays, less need for intensive care and fewer deaths, according to a new US study.
