A worker at Allegiant Stadium tested positive for COVID-19, according to stadium officials who were notified Wednesday.

Workers at the site already were adhering to the Centers of Disease Control and Prevention guidelines for the novel coronavirus — including social distancing protocols — so the worker was not in close contact with any other project workers and has been off-site since last week, according to Mortenson-McCarthy, the joint venture leading the stadium’s construction.

The worker who tested positive is self-isolating for 14 days and will not return to work until cleared to do so, the venture said in a statement.

“Mortenson-McCarthy previously implemented stringent cleaning protocols on the project consistent with CDC guidelines,” the statement said. “In accordance with those protocols, the area where the worker had been assigned, and the surrounding vicinity, was immediately shut down and sanitized.”

Work continues in other areas of the stadium project.

Mortenson-McCarthy said it has has implemented preventive policies to minimize the risk of coronavirus:

■ Strict adherence to CDC guidance, “including directing team members who feel sick or have health-related concerns to stay home.”

■ Verbal health screening of workers before they begin on-site work.

■ Social distancing.

■ Reduced concentrations of employees.

■ Monitoring and sanitizing high-traffic areas multiple times per day.

■ Making sanitizer and hand-washing stations available throughout the site.

■ “Working with customers and trade partners to adjust workflows.”

■ Teleconferencing.

■ Suspension of group activities.

“Our highest priority is the health and safety of our team members, project partners and the community,” Mortenson-McCarthy said. “We will continue to follow guidance issued by the CDC along with local, state, and federal health authorities. We will implement further changes or adjustments as needed to help protect the health and safety of everyone on the project.”
