The C.D.C.’s Covid Data Tracker, reporting results for the two-week period ending on Sept. 11, put the B.1.617.2 lineage of Delta at 99.4 percent among variants of concern, with two other Delta lineages tracked at 0.2 percent and 0.1 percent, the Mu variant — first detected in January in Colombia — at 0.1 percent and several other, unidentified variants at 0.2 percent. That data is based on thousands of sequences provided every week through the C.D.C.’s national genomic surveillance efforts, according to the agency’s website.
