ATHENS, Greece — Greece says it expects revenue from its tourism industry to drop by 80% on in 2020 due to the coronavirus pandemic.

Government spokesman Stelios Petsas says third-quarter data showed an estimated 3.9 million tourists visited Greece from July through September, a drop of 88% from 2019.

The pandemic followed a record year for the Greek tourism industry with 34 million visitors and some 18 billion euros ($21 billion) in travel receipts in 2019.

The tourism industry is a key source of income for Greece’s $200 billion economy. Greece began reopening to tourism in mid-June after strict lockdown measures kept infection rates lower than in most other EU countries.
