As per the latest data released by the CDC, by Saturday 73% of the cases reported in America were that of Omicron variant. The health officials in the United States reported that Omicron accounted for 2.9% of all cases through Dec, 11 which was later revised to 12.6%. However, now Dr. Rochelle Walensky, the director of CDC, stated on Wednesday that Omicron variant has overtaken delta strain in dominance as it accounts for the 90% cases in the United States of America.  

According to Walensky, the highly modified and contagious strain is responsible for up to 90% of infections in the eastern Atlantic, Midwest, South, and northern Pacific states. This significant growth in the fraction of omicron traveling around the country, according to her, is identical to what is seen around the world. Furthermore, compared to someone who has been completely vaccinated and received their booster, unvaccinated people are 10 times more likely to contract Covid-19 and 20 times more likely to die from the virus. Walensky went on to say that the vaccine's early results against the omicron version are promising, especially when people are boosted.

To limit the risk of transmission, US health officials advised people to get tested for Covid before meeting up with friends or family for the holidays, and to celebrate at home with others who are also vaccinated. Moreover, the United States ordered 10 million Pfizer pill treatment courses for public safety, with 265,000 treatment courses set to be available in January. The FDA has yet to approve the Merck drug, which might happen this week.
