As state health officials raised the identified coronavirus cases on Wednesday, the city of Denver announced that a Denver International Airport employee also received a presumptive positive test for COVID-19.

The employee is symptomatic and isolated from others, according to city health officials. The Denver Department of Public Health & Environment is currently tracing all contacts the employee may have had with other individuals.

“Our priority is to ensure the health and well-being of our community, and that includes City and County of Denver employees,” Bob McDonald, director of the Denver Department of Public Health & Environment, said in a Wednesday news release. “It’s important to remember that this is a dynamic situation that requires tremendous flexibility in response. Our plans and tactics will change as the situation evolves and we have new information and strategies.”

With an employee population of some 13,000 and increased local capability to test for COVID-19, “we expect to identify additional employees throughout the city, and we will update the public regularly,” the news release stated. The personal information of those affected by COVID-19 will not be shared publicly.

The airport recently announced its enhanced efforts to keep passengers and employees healthy amid a growing outbreak of COVID-19.

“We are actively monitoring and assessing the potential impacts of the coronavirus and working closely with our local and federal partners and our airlines to reduce the risk to our passengers,” airport CEO Kim Day said in a March 2 news release. “While we are providing hygiene assistance for our passengers, we strongly urge everyone to follow guidance from the (Centers for Disease Control and Prevention), including normal best practices to prevent the spread of germs.”

Part of the airport’s efforts include installing sanitary wipes in jet bridges for passengers to sanitize their plane seat; adding more hand sanitizer stations; increasing the “frequency and intensity” of disinfecting washrooms and other public areas with germ-killing cleaning agents; and using treating checkpoint screening bins with “powerful antimicrobial technology” that prevents the growth of bacteria and viruses.

DIA officials are also urging its staff and passengers to wash their hands with soap regularly for at least 20 seconds and to cough and sneeze into their elbow.

“All of these are easy and effective ways to avoid contracting or transmitting common colds, flu and other viruses,” the airport said in a statement.
