A Czech singer who deliberately contracted COVI-19 in order to obtain a health pass has died.

Proof of vaccination or a recent infection is required to access cultural and sports facilities in the Czech Republic.

Hana Horka, the vocalist for the band Asonance, died at the age of 57, according to her son Jan Rek.

Jan tells CNN affiliate CNN Prima News that his mother voluntarily exposed herself to the virus when he and her husband caught the virus before Christmas.

“My mom wanted to get sick, so she gets the COVID pass," said Jan.

“She said to me and even publicly she wants to get infected so she is done with COVID," Jan added.
