Jeffco Public Health Statement: First Presumptive Positive Case of COVID-19 in Colorado


On March 5, the Colorado Department of Public Health and Environment (CDPHE) reported that the state laboratory had a presumptive positive test result for COVID-19.

The case presented itself in a male in his 30s, who had contact with a known case of COVID-19. 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. To act as swiftly as possible, public health officials will proceed as if the case is officially confirmed.

The individual was tested at St. Anthony Summit Medical Center in Summit County and traveled to Jefferson County wearing a face mask where he is recovering in isolation in an undisclosed location, that is not a medical facility. The individual will remain isolated until cleared by public health officials. Three close contacts who may have been exposed are currently under quarantine.

CDPHE, Summit County Public Health and Jefferson County Public Health are currently working to further investigate this case. This includes identifying any close contacts who may have been exposed while the person was infectious. Public health practitioners will attempt to contact anyone who may have been exposed and monitor them for signs and symptoms of COVID-19.

At this time, we believe the risk of exposure of this case for most Coloradans is low.

A second presumptive positive case has been identified in Colorado. No additional details are available at this time.

Coloradans are advised to stay informed by visiting the CDPHE website, and to take disease prevention and preparation steps:

  • Wash your hands frequently with soap and water.
  • Cover your nose and mouth with a tissue when coughing and sneezing, throw the tissue away and then wash your hands.
  • Avoid touching your face including your eyes, nose and mouth.
  • Disinfect frequently touched objects and surfaces.
  • Avoid being around anyone with cold- or flu-like symptoms.
  • If you’re sick, stay home and away from public places.
  • Get a flu shot if you have not had yours yet.

For general questions about COVID-19, call CO HELP at 303-389-1687 or 1-877-462-2911 or email, for answers in English and Spanish (Español), Mandarin (普通话) and more.
