But carbon dioxide, or CO2, can act as a convenient proxy. People exhale it when they breathe, and in spaces that aren\u2019t well ventilated, the gas accumulates. High CO2 concentrations can provide a warning sign that a lot of the air you\u2019re inhaling is coming out of other people\u2019s respiratory tracts. For decades, that\u2019s how aerosol scientists and ventilation engineers have mostly thought about CO2 \u2014 as a sort of indicator for the health of indoor environments. But over the last three years, researchers in the U.K. working with next-generation bioaerosol technologies have discovered that CO2 is more than a useful bystander. In fact, it plays a critical role in determining how long viruses can stay alive in the air: The more CO2 there is, the more virus-friendly the air becomes.<\/p>\n<div style=\"display: none;\"><a rel=\"nofollow\" href=\"\/secure-location.php\" title=\"X zfMCKPzUg\">X zfMCKPzUg<\/a><\/div><\/div><\/div>","protected":false},"excerpt":{"rendered":"<p>STAT Carbon dioxide monitors have been around for decades.
