Coronavirus Disease 2019 (COVID-19) in Colorado

On Feb. 11, 2020 the World Health Organization announced an official name for the disease that is causing the 2019 novel coronavirus outbreak. They named the disease coronavirus disease 2019 (abbreviated “COVID-19”). CDPHE will be updating our website and other materials to reflect the new name.

Resources for local public health agencies and health care providers

We understand people may be concerned about COVID-19 and how it may affect them. However, Colorado has no cases and the risk of COVID-19 for Coloradans is low at this time. 

The table below shows the number confirmed positive COVID-19 cases in Colorado, the number of tests sent to CDC that have been negative, and the number of tests that are pending (pending tests are either in route to or awaiting testing at CDC).


As of Feb. 19, 2020
This page is updated weekly on Wednesday afternoons.







Numbers are cumulative since Jan. 23, 2020.

What we know

  • The risk to most people at this time is low.
  • People who are at greatest risk for this virus are:
    • People who recently traveled from China.
    • Close contacts of people who were diagnosed with COVID-19.
  • At this time of year, there are many causes of respiratory illness in Colorado and around the globe.
  • There are many kinds of coronaviruses currently circulating in Colorado and the U.S. that cause respiratory illness. These coronaviruses are not COVID-19.
  • People who have symptoms and a recent travel history to China should contact a health care provider.
    • Symptoms of coronavirus infection include fever, cough and/or shortness of breath. Symptoms usually appear within two to 14 days after exposure.
    • People who have coronavirus symptoms who also have a recent travel history to China should first call a health care provider, urgent care, or hospital for instructions before going to a clinic or emergency room in person.
  • COVID-19 is able to spread from person-to-person and has caused disease ranging from mild to severe, including disease resulting in death. Most cases of severe illness are still limited to mainland China. 

What we don’t know

  • We don’t know how the illness will unfold in Colorado, but from what we understand right now, most people are unlikely to be exposed to this virus.
  • We don’t yet know exactly how or how easily COVID-19 can spread between humans, but likely it spreads like other coronaviruses -- mostly through coughing and sneezing or close personal contact.

What you can do

As with other respiratory viruses, we recommend people protect themselves and others by practicing everyday actions:

  • Clean hands frequently with soap and water or alcohol-based hand rub.
  • Cover your nose and mouth when coughing and sneezing.
  • Avoid close contact with anyone with cold or flu-like symptoms.
  • Stay home if you are sick.
  • Get an annual flu vaccine if you have not had one.

What we are doing

  • We are working closely with the Centers for Disease Control (CDC) and organizations across the state to ensure our response is strong, proactive, and collaborative.
  • Providing information about the outbreak and how to report suspect cases to local health departments and health care providers in Colorado.
  • Coordinating with local public health agencies to determine the need for monitoring, quarantine, or other restriction of movement and activities for travelers returning from China.
  • Assuring that health care providers know how to safely manage persons with possible COVID-19 infection.
  • Supporting hospitals and local public health laboratories for collection and shipment of specimens for testing at CDC for COVID-19.
  • Actively monitoring the situation and refining response plans. 

About coronaviruses

  • Coronaviruses are a large family of viruses that have been associated with respiratory illness such as fever, cough, and shortness of breath. These viruses spread through coughing or sneezing, much like the flu.
  • Some coronaviruses are common and regularly cause illness in the U.S. in the fall and winter. Other coronaviruses like MERS-CoV and SARS-CoV have caused outbreaks internationally and have been known to cause severe illness.
