A South Africa trial using Far-UVC showed 90% suppression of tuberculosis transmission, and TB is approximately 10 times more resistant to Far-UVC than typical respiratory viruses like flu or coronavirus.

29:43basically senior centers are another place where we're probably going to see results relatively faster because there's just not as much social mixing there right with the rest of society. >> I would agree with that. Um and also I should point out that um we we have some really encouraging results on tuberculosis specifically. There's a trial going on in South Africa that already has preliminary results and there they're seeing 90% transmission

30:09suppression in these in these TP wards. Uh this is an animal study. So the the way it's set up is that there there's guinea pigs which are exposed to the humans only through the air and they're monitoring what percent of the guinea pigs uh get tuberculosis. Um but tuberculosis is actually not very sensitive to FR UBC at all. It's relatively resistant. Um and I would say it's about maybe 10 times more resistant

30:36than your typical respiratory virus like flu or corona virus. So in is our flu and corona virus transmitted through the air in the exact same way as tuberculosis? No, probably not. But there's there is in fact a lot of reason to be optimistic. I think Misha is totally right about long-term care centers probably seeing much more immediate benefits than you know the school or office case or perhaps uh

31:03boarding schools. I think boarding schools could be a relatively more immediate example. >> I think this is going to be interesting because um you know there are some institutions that require we're going to need a stack of academic uh papers on this that have confidence intervals etc etc. But when you're talking about 90% decreases in infections, for example, the anecdotal evidence will pile up in certain communities extremely

31:30quickly. And uh it is just nakedly and obviously incentive compatible for, you know, a case like a long-term care center. Regardless of who owns it, Pir, or otherwise, they would strongly prefer that the residents not die. And uh that is uh both like the humanitarian mission for them plus also uh they get paid based on how many residents are still living at the moment. And so uh you

31:56could imagine it um uh you know having a happy viral coefficient uh in that community of practice as soon as a chain installs it in one uh location and then is able to check at the end of the month. Oh, we had, you know, 34 infections in the median uh one of our locations and the one where we installed this, we had three and then make the
