All arrivals from the UK, regardless of vaccination status, will have to self-isolate for five days when entering the country.
They will also have to take one pre-departure Covid-19 test and another at the end of the quarantine period.
The measure was initially introduced on 21 June, to run until 30 July, in response to the emergence of the Delta variant in the UK.
But Italy’s minister of health, Roberto Speranza, announced on Thursday (29 July) that the restrictions will remain in place for another month.
