A preliminary study from Italy shows that SARS-CoV-2 can
survive on particulate matter (ie pollution). Researchers are
suggesting that industrialised areas will have bigger outbreaks of COVID-19.
Milan, the epicenter of the Italian outbreak, has the worst air
quality in Europe. Similarly Wuhan, China. An industrialised area.
Make sure you are upwind of anyone sick!

@wolfgang59 saidThat's interesting. An effect of the lockdowns is to reduce pollution, the measurements I saw were prinicpally of NOx, but we might expect particulates to be significantly reduced as well as people presumably aren't driving at the moment and diesels are popular, so there's an unexpected transmission route being cut out by the non-pharmaceutical intervention.

Interesting route for transmission of Covid. So our efforts have effects we didn't even anticipate. So one thing that comes to mind, air filters in our homes may reduce the amount of pollutants in our home air so that sound like another route to lower the odds of catching it.

@sonhouse saidSounds like a plan! 😆

@sonhouse saidIt would mean that indoors is safer than outdoors in some areas.

@wolfgang59 saidBeing outside in the sun is dependent on the UV rating at the time or what they had been that day.

@handyandy saidThanks for the link to the study. This doesn't prove anything and the authors don't claim that it does:

Although the connection can be considered both a false statement as it lacks data and causality, China has faced a near identical situation with the epicenter of the Covid-19 pandemic, where elevated concentrations of air pollutants were present in the regions mostly affected (see Figs. 3 and 4). The above studies show that air pollutants, such as particulate matter, nitrogen dioxide, and carbon monoxide, are most likely direct to facilitate the longevity of virus particles in favorable climate conditions.

What the paper does is show a correlation between atmospheric pollutants and mortality from covid-19 in both Italy and China. The authors speculate about causal pathways, that pollution increases the environmental survival time of the virus and so facilitates its transmission, and/or that pollution damages peoples immune systems so that the disease is more deadly in regions with higher pollution. What they haven't done is an experiment similar to the DHSST experiment [1] Eladar brought to our attention where laboratory experiments showed a half-life of the order of 2 to 3 minutes for SARS-CoV-2 in simulated sunshine.

Ever since they said this virus can survive about 12 hours on a hard surface, I thought:
So why wouldn't it survive 12 hours floating in a gentle wind, sort of like pollen?!!!!!!
