Early evidence suggests omicron may also produce less serious illness — though scientists caution it is too soon to say — and that it could better evade vaccine protection.

Even if it is milder, the new variant could still overwhelm health systems because of the sheer number of infections. Confirmed coronavirus cases in the U.K. have surged by 50% in a week as omicron overtook delta as the dominant variant.
