I wonder if ozone treatment would kill it. It kills household mold. We had a roof leak that molded inside a bedroom. A few hours of ozone and it was dead. Much safer than harmful chemicals. Warming: It kills house plants and goldfish too.
Not sure. These are like viral type fungal infections. Kind of how strep and staph travel. Being a chemo & transplant patient, I took anti fungal meds as a prophylactic for a year. I know a few people who did not make it due to fungal pneumonia. I could not be around plants in the house, of course not garden, etc as doing so could possibly cause fungal pneumonia.
This fungis is air born and stubborn to the available meds normally used to treat the infection.
I’m not going to ask how you know that it kills goldfish.
