“A team of researchers at Washington University has developed an air monitor that can alert users to the presence of SARS-CoV-2 — the virus responsible for #COVID-19 — in just five minutes.”

Much work to do, but this would be a gamechanger!

@luckytran I guess it would be very useful, but only if the detection events happen to be unusual enough, which doesn't depend on the detector, but the users' behaviours.

If it ends up sounding an alarm every 5 minutes, most people will just ignore it, or even choose to uninstall it and feign that nothing is happening.
