Neue Forschungsergebnisse deuten darauf hin, dass sich durch die Luft übertragene Krankheiten wie Masern, Grippe und COVID-19 über eine Art Badezimmerlüftungssystem, das weltweit häufig verwendet wird, leicht zwischen Wohneinheiten in Mehrfamilienhäusern verbreiten können.

Airborne diseases like measles, influenza and COVID-19 can easily spread between units in multi-family buildings via a type of bathroom ventilation system commonly used around the world, new research suggests.
The study, conducted inside an older high-rise in Spain early in the coronavirus pandemic, adds to a growing body of evidence that airborne viruses can spread between separated indoor spaces, transmitting disease without face-to-face contact.
“We tend to think that if we shut the door in our apartment, we are safe and can’t get infected. But our study shows that, depending on the ventilation system in place, that may not be the case,” said senior author Shelly Miller, professor emerita in the Department of Mechanical Engineering at the University of Colorado Boulder.

Can someone smarter than me elaborate on how this could affect lockdown policies in the future?
Wait, I thought we already knew this?
EDIT: I swear we talked about this in one of my college courses. IIRC, we used a case study from China. Maybe it was on SARS?
So my neighbor coughs and i get sick. cool.
So do any of the hantavirus self quarantine folks live in a building that has this?
My building has air shafts like that. But there are large fan units on the roof that pull air up through them. Causes a fair bit of negative pressure.
I guess those people also smell funny stuff for years before pandemics hit. The solutions are cheap and simple: either install a vent with directional valve to force air to be expelled at your flat or install one fan at the top to create negative pressure in the entire stack.
Also explains why airborne diseases spread like wildfire on cruise ships.
„commonly“
those are not modern ventilation, though
in french buildings, ventilation suck air with a strong negative pressure, and no other kitchen vacuum thing is strong enough to reverse this
but yeah, ventilation is quite important when it comes to respiratory health, and it’s not only covid, but mold and other things
Public transport has a similar issue for the peasants
TIL that measles is airborne?
During covid lockdown I immediately instinctively covered the bathroom vents.
Where are all the enemies of science that should be in this thread negating any scientific finding? Are you guys OK?
This is an anecdote but it is interesting, at least to me. My spouse, myself and my two kids were all vaccinated in the summer of 2021. In February of 2022, i got COVID but no other family member did. In June of 2022, my son got it but nobody else did. In simmer of 2023, we travelled to my mother’s and my wife and daughter caught it from my mom but neither I nor my son got it again. None of us has gotten it since then.
