The DuPage County Health Department reported multiple cases of coronavirus linked to an Orangetheory Fitness studio in Elmhurst.
In a statement, the health department said officials received "multiple reports" of COVID-19 cases at the Orangetheory since last week.
"In our communication with Orange Theory, we have provided public health guidance and resources, and we are conducting case and contact investigations to help determine if exposure may have occurred onsite as well as the extent of that exposure. We have also provided risk mitigation recommendations to prevent ongoing COVID-19 spread in the community," the statement read.
The Orangetheory reported 18 positive cases of the coronavirus, the gym confirmed in a statement Tuesday.
"We are concerned about all involved and are hopeful that everyone will quickly return to health. We are working with local health authorities in the contact tracing process to identify any additional cases as soon as possible. We are constantly examining and evolving our internal policies and processes to ensure the safety of our staff and members, and are committed to ongoing vigilance in all of our studios," the statement read.
The fitness studio, located at 135 N. Addision Ave. in Elmhurst, closed from Thursday to Sunday to investigate the outbreak and do a deep cleaning.
