A more contagious subvariant of omicron, known as BA.2, is spreading across the globe and could soon become the dominant version of Covid-19.It's now the top variant in at least 18 countries and rapidly spreading, representing 35% of all new cases that have been genetically sequenced worldwide, up from 10 countries and 21% of cases the week before, according to new data from the World Health Organization. In the U.S, BA.2 currently makes up 3.8% of genetically sequenced Covid cases, according to the Centers for Disease Control and Prevention.To facilitate the mutant-related research, drug trials and vaccine development, a high-throughput assay to measure IgG antibodies against the mutants is in urgent need. |
