“If BA.2 follows the same pattern in the U.S. as observed in countries like the United Kingdom, Denmark or India, we could observe a slowing of the current decline in new cases,” said Ramon Lorenzo-Redondo, the bioinformatics director at Northwestern Medicine’s Center for Pathogen Genomics and Microbial Evolution, in a news release. “In this case, the number of new cases could stabilize for a while before starting to decrease again. It is still too soon to know because there are still very few BA.2 cases in the U.S.”
