We are 4th (!!!!) in the world in cases per million people... only behind Qatar, Vatican City and San Marino...
This week it was announced that quarantine measures will be more strict from now on and there will be stronger sanctions for those who violate quarantines. But I don't know about 5 years in jail; maybe it's one of the new measures taken this week but it definitely wasn't the case till this Tuesday.
Okay... did some reading (because I'm keeping myself away from the news since the last 2 weeks...) and yes. Since yesterday there's stronger sanctions to those who violate the restrictions, including up to 3 years in jail for serious offenders and even 5 years for the worst cases. Also bigger fines and sanctions to those who organize massive events, violate quarantines or curfews (there's been MAAANY clandestine parties during this time, with little to no sanction apparently).
There's also big fines and up to 3 years jail time for employers who force their employees to work while infringing the restrictions.
