COVID-19 strains

December 8, 2022

As it gets colder and more people move their activities indoors, the recent decline in COVID-19 cases across the United States has started to level off. At least half a dozen versions of the virus, all variants of Omicron, are competing to become the next dominant strain in the U.S. Currently, the BA.5 subvariant still causes just less than half of infections, but two other sub variants are growing and are expected to outcompete BA.5 – BQ.1 and BQ1.1, according to the U.S. Centers for Disease Control and Prevention. Other variants have also gained some ground. The evolution of virus variants is nothing new; viruses constantly try to adapt. Health experts say the best thing people can do to protect themselves is to be vaccinated and boosted.
