They had to do something

Yes, the same thing that clearly hasn't worked so far was the obvious choice wasn't it...? 
It was working and seems they then relaxed it. Lockdowns work at suppressing the cases until vaccination creates herd immunity. Half arsed lockdown lites don't especially when new variants emerge.
Just look at the caseload curve

Not really no...

We're still under lockdown restrictions, only allowed out twice a day (after seeking permission via SMS), masks everywhere, no indoor drinking or dining... The only real relaxation has been allowing outdoor dining and drinking...
From Monday we'll be even more locked down, only allowed out once a day and everything closed again - no doubt 'non-essential items' roped-off in supermarkets... Apart from Easter when the virus is apparently taking a holiday...

The facts are that Lockdown hasn't worked as claimed on the tin. If it did, we wouldn't need to go into a third on Monday (which in itself is causing shops, bars and restaurants to be rammed this weekend

)
Perhaps it is a cultural thing, Cypriots like to shop daily... Perhaps it is a 'small number of idiots that don't obey the rules' but that isn't my observation, masks are everywhere (even single drivers in cars) and the expats are fanatical about the rules... Perhaps it is keeping people locked-up and away from fresh air and sunshine that is having an effect on the numbers...?
Bottom line is that Locking down has put the economy in the toilet and hasn't had an effect on the numbers - nor can anybody here explain why the numbers are rising...

And people are completely fed up with it now, they've obeyed the rules, they've watched the businesses of friends and relatives collapse (a friend that has run a hairdressers in the village for years threw in the towel after yesterday's announcement) and here we go again into yet more restrictions.
