Same here with gyms. I have never caught anything and especially not ringworm from a gym. But if I had caught ringworm not to fear ivermectin was available.In 40+ yrs of lifting at various gyms I can't say I've ever experienced anything like that. This goes back to my intial lifting days in HS & college football (late 70s) up through to the present day. I did 10 yrs of competitive bodybuilding & powerlifting back in the 1980s at a real dump of a gym that was exclusively for hardcore bodybuilders. The owner, a thirtysomething struggling bodybuilder, lived in a little room in the back of gym. He couldn't afford custodial staff & he never bothered cleaning the joint himself. This was a real cesspool for germs and I was surprised I've never got any bacterial infections. Lol. Nowadays, the gym I'm at is state of the art in equipment, locker room facilities & aquatics area. Plus the staff wipes down & sanitizes the equipment still every hour or so (Covid protocol upon re-opening). The gym is actually more sanitized than my home. Lol.
