A worker at Disneyland Paris has tested positive for the COVID-19 coronavirus.
A spokesman for the park said the maintenance person had not come into contact with visitors and other staff were being checked.
The theme park remains open.
It comes as deaths from the virus in Italy have jumped from 233 to 366 - a 57% increase.
Italian Prime Minister Giuseppe Conte said he will use "massive shock therapy" to battle the outbreak.
The rise was by far the largest daily rise in fatalities since the start of the crisis there last month.
The confirmed cases in Italy also went up by 25% - from 5,883 on Saturday to 7,375 on Sunday.
Of those diagnosed with COVID-19 - the disease caused by the coronavirus - authorities said 622 had recovered on Sunday, compared with 589 the day before.
With 16 million ordered on lockdown in northern Italy, Mr Conte has said he will significantly increase spending on coronavirus measures as a form of "massive shock therapy" to try to slow the disease.
"We will not stop here. We will use a massive shock therapy. To come out of this emergency we will use all human and economic resources," he told newspaper la Repubblica.
He also said he would decide in the coming days whether to further extend the closure of schools - and confirmed he had tested negative for the virus.
Italy's economy minister last week pledged €7.5bn in measures to help the economy deal with Europe's largest outbreak.
Two new cases of COVID-19 were confirmed here on Sunday.
