So far, no variants other than B.1.1.7 have appeared in Colorado, but the CDPHE stresses that staffers are on the lookout for them. "The Colorado State Laboratory has set up a statewide sentinel surveillance program for whole-genome sequencing of COVID-19 positive patient samples from across Colorado," a department spokesperson notes. "In addition, we are asking any other labs that have identified potential variant samples to forward them to the state lab for sequencing." The only other mutation to make it to the U.S. thus far is known as the Brazil P.1 variant; the first case was detected in Minnesota this week. But on a page devoted to the subject, the federal Centers for Disease Control and Prevention confirms that "multiple COVID-19 variants are circulating globally."
