2) Multiple models show #XBB15 is much worse in transmission R value and infection rate than previous variants — faster by LEAPS and BOUNDS. @JPWeiland did some the earliest models on #XBB15 watching data in NY. it has only grown worse nationwide. ImageImageImage
3) in fact, when @JPWeiland first modeled #XBB15 before Xmas, the data shows XBB15 was 108% faster than the previously king #BQ1 variant. But with more data, XBB15 has further accelerated to now being 120% faster! ImageImage
