The variant was found in a man in his 20s who is in isolation southeast of Denver in Elbert County and has no travel history, state health officials said.

Elbert County is a mainly rural area of rolling plains at the far edge of the Denver metro area that includes a portion of Interstate 70, the state’s main east-west highway.

Colorado Politics reported there is a second suspected case of the variant in the state according to Dwayne Smith, director of public health for Elbert County. Both of the people were working in the Elbert County community of Simla. Neither of them are residents of that county — expanding the possibility of the variant’s spread throughout the state.
