A growing number of cases of a hybrid COVID-19 variant dubbed “Deltacron” are being identified, including several cases in the United States.

Researchers with Helix, a California-based genomic company, found two cases of COVID-19 infection caused by a hybrid of the Delta and Omicron variants, while researchers in France determined 18 people were infected by the hybrid.
