> Why haven’t we already seen the same kind of transformation with respiratory viruses? Because it’s a lot easier to control the supply of a material that has to be actively transported into people’s houses for them to use? I struggle to take them seriously when I didn’t see this basic and fundamental difference even mentioned.
Came here to say the same thing. It's simple to clean all the water you consume, cleaning all the air you breathe is impossible unless you want to walk around like Bane. Bizarre that they don't mention this when comparing respiratory infections to waterborne infections.
But you’re not carrying around your own water treatment mechanism either (unless you’re out hiking). It is relatively easy to install air purifiers or UVC lights in offices, schools, grocery stores, etc. The problem is that people don’t care enough about air quality and the ROI isn’t clear. Increasing the ventilation rate in an overstuffed co-working space has cost implications for the operator, but it doesn’t increase revenue.
