Most travellers entering Cuba as of Feb 6 will be quarantined for up to a week, the government announced, and flights from the United States and some other countries reduced to no more than one per week per airline.

Tourists will have to remain in hotels at their own expense and residents in special centres free of charge until a test at five days comes back negative, Reuters reported.

Visitors already must arrive with proof of a negative test for the new coronavirus and take another one at the airport.

Some resorts isolated from the population may have looser rules, and diplomats, businessmen, foreign students and journalists will each have their own locations and protocols.
