I did not watch the panel, and do not know the answer, but I know that Incline Village (Tahoe) and nearby Truckee had a major mold problem and some of the schools and buildings were later deemed with SBS (sick building syndrome) similar to the bldg I worked in for 10+ years in my career which was condemned in an earthquake and had mold, chemicals, asbestos, etc, yet they allowed us to continue working there.
I also lived in a rental with toxic mold during the same time period (yes I have bad luck extraordinaire). I know in my own illness, mold/mycotoxins were the final blow to my immune system which caused me to lose the ability to tolerate food and developed severe MCAS in 2015 (which has now been reversed). If I had not moved away from the toxic mold and sick buildings, I do not believe my current treatments would have ever had a chance to work. But I am just speaking about my own case and never presume it applies to others.
