Schlager singer Tony Marshall ("Beautiful Maid") is being treated in the intensive care unit after being infected with the coronavirus.

This was confirmed by his manager Herbert Nold of Bild am Sonntag.

Accordingly, the 83-year-old has to be artificially ventilated.

"We don't know where Tony got the infection," Nold told the newspaper.

The singer was vaccinated twice, always wore a mask and kept his distance.

In the past, Marshall has struggled with health problems.

In 2019, he suffered a stroke and kidney failure, but recovered and performed in front of an audience until the end.

A performance planned for Sunday at a carnival club has now been canceled, according to Nold: "After 8,000 appearances, it is the first time that I have to cancel a performance by Tony."

Marshall was born Herbert Anton Bloeth in Baden-Baden in 1938.

The trained opera singer became known in 1971 with the hit "Schöne Maid".

According to his own information, he has published 120 singles.

On the occasion of his 80th birthday in 2018, Marshall said in an interview with the FAZ: "I am a person who likes to be surprised, and that I was allowed to live that old is the biggest surprise."
