Here's something /never/ considered by politicians nor health care personnel:

AC-systems of public buildings, offices and apartment-blocks.

Having worked as a cleaner, I can testify to the fact that it is normal to not clean those or swap any filters unless the system breaks down or people start complaining about bad smells, mould et c.

Finding foot-thick layers of dust with things growing in and on the ventilation-system is standard, especially for public/municipal buildings such as hospitals or administrative offices.

Schools and kindergartens specifically are notorious offenders when it comes to dust, mould, moss, fungi and other crap in the ventilations systems.

Reason for this? People thinking AC is better than opening a window (granted, huge complexes can't do that due to sheer size - maybe don't build that way, hm?) and the time/cost associated with cleaning AC and ventilation systems.

And don't get me started on the coffee-vending machines...
