Cuba reported a record 93 cases of the new coronavirus on Monday as a surge of the disease in the Havana area threatened to stall the re-opening of the country after a partial lockdown beginning in March.

Most of the cases were in Havana, where a partial lockdown was re-imposed on Monday, and in neighboring Artemisa province. The area has been isolated from the rest of the country where with but few exceptions no cases have been reported in more than two months.
