South Carolina officials have confirmed the United States’ first two confirmed cases of the more contagious coronavirus strain. This more contagious strain was first spotted in South Africa.

Currently there is no travel history or connection between the cases. Both confirmed cases have been adults, according to a release from the South Carolina Department of Health and Environmental Control.

Both confirmed cases were originally tested in early January and are no longer contagious, and are doing well. According to Dr. Brannon Traxler, the health department’s interim public health director, the reason for the delayed report is that it takes a while for sequencing to be done.

One case was confirmed to officials late yesterday by the US Centers for Disease Control and Prevention, and the other was identified by the state’s public health laboratory while testing samples over the past several days.
