Using indoor CO2 levels to find out how much of other people’s breath (virus) you breathe in: 1 of 2

Is it possible to crush coronavirus like a bug? Without devastating lockdowns? Yes, we are all hoping for vaccines, and ones that work for the new strains that are more transmissible. In this video and the next, I make the case for widespread installation of carbon dioxide monitors in all indoor public spaces. We have smoke detectors to warn us and keep us safe from fires. We have carbon monoxide detectors to keep us safe from harm from incomplete combustion heating systems. We put chemicals that smell like rotten eggs into natural gas to keep us safe from leaks. Now, to fight coronavirus, and all other airborne virus like Spanish flu, SARS, and MERS, and future viruses we need to measure indoor air quality and ventilation. Carbon dioxide is a perfect proxy for real-time measurement of the virus. Outside, virus transmission is extremely low, almost nonexistent with social distancing, and CO2 levels are about 420 ppm (parts per million), on average. We need to put carbon dioxide monitors inside all schools, long-term care homes, restaurants, stores (i.e. all public spaces) to avoid cyclical lockdowns. If indoor CO2 concentration levels are close to external, say 400 to 600 ppm, the coronavirus transmission risk is extremely low. If they are about 800 ppm, or even higher the transmission risk is much higher. Open windows, ventilate; otherwise clear people out of the room. At 800 ppm, the rebreathe factor means that 1% of the air you breathe is air that somebody else in the room exhaled. Many public spaces, like schools are often 1000, 2000, even 5000 ppm, and any virus particles in that space will circulate in the air for many hours, even after people have left the room. Perfect for spreading. Measure carbon dioxide as a proxy for real-time virus risk monitoring. Train medical doctors and virologists and engineers on how vital this is. It really is this simple.
