Colorado Department of Public Health and Environment has identified the first case of COVID-19 in a Jefferson County resident.

On Tuesday, Jefferson County Public Health was notified that CDPHE’s state laboratory had confirmed that a Jeffco man in his 50s had tested positive for the virus. According to a release, the man is isolated in a medical facility and in stable condition.

Because the testing was done at the state level, the case is a “presumptive positive” and results will be sent to the Centers for Disease Control and Prevention (CDC) for confirmation.

“We wish this patient a quick and complete recovery,” said Dr. Mark B. Johnson, the Executive Director at JCPH. “JCPH is working closely with CDPHE to identify close contacts and continue this active investigation. As the situation around COVID-19 develops, we will continue to work together and do everything we can to keep our community as safe, healthy and informed as possible.”

Christine Billings, the Incident Commander and Emergency Preparedness and Response Coordinator at JCPH, said the agency has been working to organize its response to COVID-19 since the emergence of the disease.

“Though of course, we wish we could prevent all spread of disease, it is through the collaborative efforts of our national, state and local partners — and our residents — that we’re able to appropriately respond when the inevitable does happen,” Billings said in the release.
