Kickboxing champion Frederic Sinistra passed away at 41 following his refusal to accept that Covid-19 is dangerous and attempts to cure himself at his home. His partner confirmed the news on December 16.

Frederic Sinistra was infected with Covid-19 in November 2021 and was immediately taken to the hospital. Reports say that his lungs were affected because of the virus.

Sinistra discharged himself from a hospital in Liege, Belgium, and denied being infected with the deadly virus, which he called a little virus. However, he died due to Covid-related complications after a few weeks.

Reports say that Frederic Sinistra spoke to his followers on social media and said he would treat himself away from the hospital. Posts shared on his Facebook page show him in a hospital bed inside the intensive care ward with an oxygen tube on his nose.


Sinistra shared another video on Facebook where he seemed to have some breathing problems. He called Covid a little virus in other posts and was entirely against the measures taken by the government to control the spread of the virus.

In an interview with the Belgian publishing company SudInfo, Sinistra's coach Osman Yigin stated that he told his ward he would not train him until the former went to the hospital for his treatment.
