A Guide to Keeping Up With the Sub Variants of COVID-19
Excellent article by Lewis Jacobson published in Politifax, May 6, 2022. It provides a guide to keeping up with an ever-changing variants of the Omicron virus.
The omicron subvariants seem like an alphabet soup of letters and numbers. The original omicron variant was called B.1.1.529. They all differ from each other by having different mutations in the spike protein. Generally, the higher the number following “BA” in the subvariant’s name, the more infectious that subvariant is. In the United States, for instance, BA.1.1 was dominant in late January, having overtaken the initial variant, B.1.1.529. But by mid-March, BA.1.1 began losing ground to BA.2, which became dominant by early April. By late April, another subvariant — BA.2.12.1 — was gaining steam, accounting for almost 29% of infections, according to data from the Centers for Disease Control and Prevention.
Why Is This Important? With only 65 % of the world’s population immunized with at least one dose of the COVID-19 vaccine, there will be new variants. Keeping up with them and their potential to infect, to keep yourself and your family safe.
