The restaurants are reportedly responsible for the second-highest number of COVID-19 infections in El Paso County after a nursing home, according to the Colorado Springs Business Journal.

"Based on Public Health’s follow up and investigation, In-N-Out is adhering to frequent cleaning and disinfecting protocols, in addition to enacting employee screenings, exclusion of ill employees, and cohorting staff," Public Health told the Colorado Springs Business Journal in an emailed statement. 

"Recommendations to temporarily close are given when transmission within the facility is identified and to allow for proper cleaning and disinfecting." 

No customers appear to have been infected, the Public Health Department confirmed.
