During his Talk is Jericho podcast, Chris Jericho revealed that he tested positive for Covid-19 in 2020:
“I tested positive, maybe back in September. and I had zero symptoms. One of the ones that you said… I had my ten days in isolation. Stayed away from everybody. And, I didn’t have a symptom, I didn’t even know I had it. I went and got tested just in general, and it’s one of the ones where they said I was positive, and I was like, “Really?” You serious?’,”
“And I had nothing, like I didn’t have a headache, I didn’t have a cough, which is a very lucky thing. But I think, on top of that, Alex, and you’ll know this… once I did have it and it wasn’t a false positive ’cause I took three different tests and they were all positive, but now, I have the antibodies.” (quotes courtesy of RingsideNews.com)
