Omicron cases not as prevalent as CDC originally thought
(KYMA, KECY) - Despite this surge, the omicron COVID variant may not be as prevalent as previously thought.
The Centers for Disease Control and Prevention (CDC) is adjusting its estimate of the variant's infection rate down.
The CDC now believes omicron was responsible for 58.6% of new cases in the U.S last week.
That's down from the agency's previous estimate of 73.2%.
Because not every COVID test goes through genetic sequencing to determine what variant caused it, it's extremely difficult to pinpoint how many cases each variant causes.
Also, many COVID infections never get tested at all.
