A second suspected mutant COVID-19 infection was found in Colorado, USA.

A county public health director in Colorado said that they had found a second case of local mutant COVID-19 infection, which experts said may be extremely infectious. The day before, the first case of mutant virus infection was reported in Elbert County, Colorado, United States.

Public Health Director Dwayne Smith told CNN that both confirmed cases and suspected instances were working near Simla, which is located about 45 miles northeast of Colorado Springs.

“Neiwin are residents of Elbert County, they are quarantined outside the county,” Smith said. “There is no indication that the virus has been spread widely in the community at this time.”
