A long and detailed Twitter thread by Vinod Scaria on the rise of the AY.3 Delta plus variant in the USA which seems to be outcompeting Delta B.1.672 in some states. Outbreak.info is showing that AY.3 genomes are found in 37% of recent sequences.
Closely tracking the delta+ lineages now across the world, one of the lineages AY.3 seems to be emerging in the United States of America. This tweetorial is to summarise the observations. I will be updating this thread as new evidence emerges.
