It really is a small world.

A worker at Disneyland Paris has tested positive for the coronavirus outbreak marching its way across the globe — but Europe’s biggest theme park is remaining open for the thousands who head there each day, it said Monday.

The unidentified maintenance worker had already been on sick leave for several days before he was confirmed to be Covid-19-positive on Sunday, according to Le Parisien.

He was being treated in a hospital Monday and at least three colleagues who work closely with him were ordered into quarantine, officials told the French newspaper. The park says it has more than 15,000 staff.

Officials said it will remain open, however — insisting the sick staffer only worked overnight and was not in contact with the public.

The decision to keep operating the theme park — which has had more than 300 million visitors since opening in 1992 — stands in stark contrast to Disney’s Asian parks, with those in Shanghai, Hong Kong and Tokyo all closing during the outbreak. Shanghai Disney Resort partially resumed operations Monday, the company said.

The French park is “carefully monitoring the situation” and has enforced extra cleaning of the site, Disneyland Paris said in an online advisory about the coronavirus, of which France has seen more than 1,200 cases.
