CDC Says Covid Whiplash: Now Dominant BA.2 Variant Has Been Quickly Overtaken by Another Fast-Growing Branch of Omicron in the US

Perhaps another faster-growing version of Omicron will quickly invade, as most Americans are swept away by the BA.2 variant of Omicron, which less than a month ago surpassed the original Omicron as the dominant species in the US.

Omicron’s new BA.2.12.1 bottom line now specifically accounts for 19% of all new cases assigned to current options in the country. Data released Tuesday by the US Centers for Disease Control. This means that the strain that was barely visible on the national radar two weeks ago is now identified in 1 in 5 new cases, down 1.5% from 3/19 a month ago. As Americans try to keep up, they may experience some sort of variability.

Last week, when Deadline first reported BA.2.12.1, the option was tied to a parallel upgrade of another BA.2 subline, BA.2.12. According to the New York State Department of Public Health, both are subdivisions of the BA.2 variant and are believed to have a 23% to 27% growth advantage over BA.2. BA.2 is believed to have a 30% growth advantage over the original Omicron.

New York officials announced last week that “by March, BA.2.12 and BA.2.12.1 had suddenly emerged above 70% in central New York and over 20% in neighboring New York. Finger Lakes Region. April data shows the level in central New York is now over 90%.

Then: “State health officials have determined that these new highly infectious options are likely to increase incidence.”

At the end of the first week of March, the 7-day average daily number of new cases in the state was below 2,000, while as of April 13, the total number of new cases rose to over 5,000, according to the New York Times. the number of positive cases that day was 6,546, according to state data. Since then, the number of cases has risen and fallen with fluctuating daily test numbers, while the average 7-day test positivity in New York has risen from 4.6% to 5.9%. %.

BA.2.12 is said to have originated in North America and Europe, while BA.2.12.2 originated in the USA and Canada, and some suggest the first case was detected in Canada. This might explain why it flies faster in the northeast.

CDC data released this week show that for the three states of New York, New Jersey and Connecticut, BA.2.12.2 already accounts for the majority (52%) of new cases. The Citizen sub-variant, BA.2.12, failed to keep up. Their numbers are now multiplied by cases from BA.2. Together they account for 46% of new cases, which is 85% less than data for the region released just a week ago.

In the Southwest region of California, Nevada and Arizona, new CDC data show that BA.2.12.2 is responsible for about 9% of new cases.

However, some states, such as California, are not crashing the Omicron Underline data, a practice that makes it difficult to trace the rise of BA.2 and now makes it difficult to plot BA.2.12.1.

But the state’s largest metropolitan has released data showing that as of April 2, BA.2.12.1 accounted for only 2% of consecutive cases. However, this number is over two weeks old. As of this date, the option attributed to cases at the national level has doubled. Given the trends surrounding the new subdivision, it is reasonable to assume that the same is happening in Los Angeles, especially as cases have steadily increased over the same period.
