Inga Rasmussen, 85, from Denmark and Karsten Tüchsen Hansen, 89, from Germany have continued to meet each other, sharing a drink and chatting at the cross-border of their states.
The Germany-Denmark border was closed two weeks ago amid the outbreak.
“It’s sad, but we can’t change it,” Ms Rasmussen told German public broadcaster Deutsche Welle.
Both have become local celebrities during the crisis after the mayor of the local town of Tonder found the pair while he was on a bike ride.
The pair first met two years ago, and for more than a year have spent nearly every day together.
Ms Rasmussen drives to the border from her town of Gallehus, while Mr Hansen rides his bike from Süderlügum.
He will sometimes have a glass of schnapps during their meeting, but Ms Rasmussen sticks to coffee. “After all, I have to drive a car,” she told Danish newspaper Der Nordschleswiger, BBC reports.
