The staff member was found to have been infected by Covid-19 over the weekend, a spokesperson for the theme park confirmed to Reuters and other media outlets.
The park, which remains open to visitors, said the affected worker had not come into contact with any visitors. Other employees who worked alongside the staff member were being checked to see if they had also contracted the virus.
Reports in the French media added that supplies of alcoholic hand gel were being made available to Disneyland Paris visitors, as well as staff trying to keep guests a “safe distance” apart when queuing up for rides and other attractions.
