Real-world data show that filters clean Covid-causing virus from air

I assume those floor drains lacked a functional p-trap because I've read with covid that disease would spread through drains without a proper p-trap, but otherwise the p-trap prevents drains like toilets and sinks from stinking and allowing contaminated air through.

P-traps can dry out though, but they stink if they do. Maybe that's what happened there?

Edit: yes, that's the theory - floor drains with dry u-bends allowed the poop air out.

It also had a cracked vent pipe. Sickness was correlated with floor level (the higher the floor level, the higher the infection rate).

The important takeaway is SARS 1 had significant fecal-oral transmission and not just respiratory.

And yet I'm supposed to believe that SARS 2 is respiratory only despite the fact that the government has detected SARS 2 in sewer systems, one of the early Covid symptoms is diarrhea, and SARS 1 had significant number of infections by fecal matter.

It seems to be a problem with older east Asian construction, I claim no specific expertise on the issue but I've observed poor p/u bend water barriers in even fairly nice buildings from the 70s and 80s in Taipei.

They don’t allow s-traps or u-traps in new US construction, either. I believe that it’s p-traps only.

Hopefully this will help.
