(Hill) – The Centers for Disease Control and Prevention (CDC) on Tuesday significantly revised down its estimate of the percentage of new COVID-19 infections in the US caused by the omicron variant of the virus.
According to agency data, omicrons accounted for about 59% of all infections in the United States as of December 25. Previously, the CDC said the omicron variant accounted for 73% of all cases for the week ending December 18. But that number has now been revised to 22.5% of total cases.
The omicron variant is highly transmissible and spreads rapidly, leading to increased infections even in vaccinated individuals. However, experts say, those who are vaccinated, and especially those who have received a booster shot, are well protected from severe illness from the variant, meaning it is at greatest risk for those who get sick. unvaccinated people.
The new estimates mean that while the majority of new infections are attributed to the omicron variant, the delta variant has not been eliminated and still accounts for about 41% of infections.
“Ignoring the question of how the original estimate was so inaccurate, if the CDC’s new estimate of Omicron prevalence is correct, it would suggest that a large portion of current hospitalizations are The current situation we are seeing from Covid can still be caused by a Delta infection,” said former Food and Drug Administration Commissioner Scott Gottlieb tweeted on Tuesday.
The omicron variant has some ability to evade vaccine protection, particularly in causing infections in unvaccinated individuals. That means breakout infections are becoming more common.
While evidence suggests omicron infections may be milder for fully vaccinated people, experts say the experience may not be pleasant and people with such infections could end up sick. for many days.
According to the CDC, the US currently has an average of more than 206,000 new cases per day and this number is still growing.
