ROME — The Sicilian town of Corleone, made famous by the fictional Mafia clan in “The Godfather,” has ordered schools closed and a limited lockdown because of a coronavirus spike.

The city administration told all guests at a wedding on Sept. 12 and anyone who lives with them to self-isolate and inform their doctors and city health authorities. In a Facebook post, Mayor Nicolò Nicolosi said he expected “maximum cooperation to overcome the current crisis.”

The town, which is part of the province of Palermo, has reported at least five positive cases in recent days. News reports said they were tied to a wedding reception involving some 250 people.

Like the rest of southern Italy, Sicily has seen a new spate of infections since August, with more than 500 of its 5,500 cases overall registered in the past three weeks.

The Corleone administration ordered schools closed, put a curfew on bars and suspended the weekly market and other public gatherings.

Corleone was the home and last name of the fictional crime clan in “The Godfather” movie. It was also the real-life stronghold of the late convicted mobster and reputed chieftain, Bernardo Provenzano. In 2016, the Italian government dissolved the municipal government after determining the mob had infiltrated it.
