Why not drone mounted ‘Mob’ Scanners?

 All viruses and bacteria have their own specific shapes and we have our own mechanisms to zoom our view into anything to any extent. Also we have adequate AI algorithms which can interpret any virus shapes on target images and alert us.

Then what is preventing us from developing drone mounted ‘mob’ scanners to scan the crowds in public places like Airports, Stadiums and even theatres to identify the large scale presence of dangerous organisms in individuals or areas?

For those who doubt our capabilities for imaging such dimensions, here is a recent invention that can even see viruses. https://lnkd.in/gKdUvjh
