Los Angeles County Public Health officials announced today that the county of 10 million people had finally begun to experience a trend that has already hit many parts of the United States: a rapid rise in the number of Covid cases attributed to the more transmissible Omicron BA.2 variant.
Per L.A. County:
Although the current sequencing sample represents a small fraction of all cases, it indicates that between February 27- March 5, 14.7% of sequenced cases were the BA.2 Omicron sub-lineage in LA County. This is an increase from 6.4% of sequenced cases in the prior week.
Just last week, the county’s director of Public Health, Barbara Ferrer, described the increases in BA.2 as “a gradual growth.” Things seem to have changed. The ascent from 6.4% of sequenced cases to 14.7% means an overall 129.68% increase in the variant. By almost any measure, that is not gradual growth.
Dr. Anthony Fauci expressed concern on Sunday that the rapid rise in cases in Europe, which was preceded by a rapid rise in BA.2 sequences, could become the pattern stateside. In the U.K., for instance, the number of recorded Covid cases has risen from a recent low 7-day average of 33,000 on February 25 to over 106,000 yesterday.
“We are closely tracking the information from Europe, as patterns seen in Britain, in particular, are historically seen in the U.S. a few weeks later,” said Ferrer last week.
“It’s challenging to tease out the role of BA.2 in the increasing case counts in Europe. BA.2 arrived in each go these countries at a different time, but the rising case counts are happening at a similar time across most of Europe, which might suggest that the circulation of BA.2 in these other countries is not the only factor in increasing case counts,” she
