The Omicron strain accounted for 90.3 per cent of the latest group of samples sequenced by NCIPD, up from 78.2 per cent in the previous batch announced by NCIPD last week.

Among the patients with the Omicron strain, 523 were undergoing treatment at home, 39 were in hospital, 46 had recovered and five had died, as of February 1-7, the NCIPD statement said.
