Globally, the XDV.* variant clan (led by NB.1.8.1) is showing a strong but slowing growth advantage of 5.1% per day (36% per week) over the dominant LP.8.1.* variants. That now predicts a crossover in late May.
Strong growth advantages like that (if sustained) could point to higher waves than those seen for LP.8.1.* (which were typically very low).
