XBB.1.5 has become the “most popular strain” in the United States, with the strongest immune escape ability in the world

The latest data released by the U.S. Centers for Disease Control and Prevention (CDC) show that last week, the Omicron subtype XBB.1.5 accounted for 41% of new crown cases in the U.S., replacing BQ.1.1 and BQ.1. XBB.1.5 has risen rapidly in the past week, and the proportion of infections has almost doubled. Studies have pointed out that the pathogenicity of XBB has not been significantly enhanced, but because the mutation of the strain can better bind to human cell receptors, the immune escape ability is higher. CDC previously pointed out that BQ.1 and XBB branches have been introduced into my country, and their spreading advantages will gradually increase. | Related Reading (Wall Street Insights)
