Italy is scrambling to counter a coronavirus outbreak after a sharp spike in cases and deaths made it the worst-hit country outside Asia.
The two most infected regions are Lombardy and Veneto in the north, which contain the major cities of Milan and Venice.
Italian officials estimated on Monday that about 100,000 people in the country were affected by travel restrictions. Schools, museums, and theaters across the region have been closed in these areas.
Police officers and members of the armed forces have been given the authority to enforce the lockdown, the BBC reported.
Italians or people who had recently visited Italy have tested positive for the coronavirus in Algeria, Austria, Croatia, Romania, Spain, and Switzerland.
