Italy is to require people who arrive from Britain to do five days of quarantine as well as take a Covid-19 swab test, starting on Monday.
The Italian health minister, Roberto Speranza, said he signed the order as concern builds about a soaring increase of coronavirus cases in Britain involving the delta variant.
That variant is responsible for over 90% of the new infections in the UK. So far, it has been detected in relatively few infections in Italy.
The new requirement could have consequences for the Euro 2020 soccer competition, since England’s national team is likely to play in Rome if it advances from the group stage.
US travellers who flew into Italy on Covid-tested flights, which require a negative swab test within 48 hours before boarding, could already enter Italy as tourists.
Alitalia and at least two US airlines have been operating those flights, which also require a swab test for passengers when they disembark in Italy.
Tourism, especially by US visitors, is an important part of Italy’s economy, and the sector is eagerly awaiting Americans’ return.
