The person infected was described as a Martin County man in his 20s with no history of travel, the state Department of Health said Thursday.
The first case of the new strain — called B.1.1.7 — in the United States was announced Tuesday. Colorado health officials said an Elbert County man in his 20s was in isolation after becoming infected. It has since been found in California as well.
The variant was first discovered in the United Kingdom, and prompted tough lockdown and travel restrictions.
