New Research Links Air Pollution To Higher Coronavirus Death Rates (nytimes.com) 81

Coronavirus patients in areas that had high levels of air pollution before the pandemic are more likely to die from the infection than patients in cleaner parts of the country, according to a new nationwide study that offers the first clear link between long-term exposure to pollution and Covid-19 death rates. From a report: In an analysis of 3,080 counties in the United States, researchers at the Harvard University T.H. Chan School of Public Health found that higher levels of the tiny, dangerous particles in air known as PM 2.5 were associated with higher death rates from the disease. For weeks, public health officials have surmised a link between dirty air and death or serious illness from Covid-19, which is caused by the coronavirus. The Harvard analysis is the first nationwide study to show a statistical link, revealing a "large overlap" between Covid-19 deaths and other diseases associated with long-term exposure to fine particulate matter. "The results of this paper suggest that long-term exposure to air pollution increases vulnerability to experiencing the most severe Covid-19 outcomes," the authors wrote.

    I think air pollution has been linked to respiratory problems in general, which COVID-19 just takes and goes nuts with.
    • by Rei ( 128717 )

      Exactly... this is both perfectly logical, and fits with the data amazingly well.

    • I think it's the other way 'round. COVID is a disease that attacks your lungs, and if they are already damaged by other means and your lungs are already working at capacity just to keep you alive because years of pollution, smoking and whatnot damaged them to the point where you're a candidate for COPD, any additional damage COVID does pushes you over the edge.

      That might also be a good explanation why small children are curiously immune to it all. Their lungs are usually in pristine condition.

    • Local air pollution is also linked to population density and to not giving a crap about the people. Besides also death and all kinds of respiratory trouble.

    Air pollution has a high correlation with population density. Areas with dense populations are seeing the most COVID-19 infections. The hospitals in these urban areas are stressed to capacity or beyond, which results in a reduction of the resources (staff, ventilators, etc) available for patient care. That directly results in a higher mortality rate.

    Not saying that air pollution isn't a factor, especially since this is a respiratory illness and air pollution damages the respiratory system. I'm just pointing out that there are almost certainly many other factors involved here.

    • Agree, I think the study is iffy. Consider SK. Pretty high pollution levels and yet they have one of the best recovery rates. NYC in particular recently is rationing care. Not good for your mortality rates.

      Nope: "And they adjusted for various other factors that are known to affect health outcomes, like smoking rates, population density and poverty levels."
      • They found an area with high population density and low particulates?

        • I don't know offhand how much variability in pollution they found among similarly dense areas, or how much would be required to establish this link.

          Mainly it just kind of bugs me that on every /. article everybody jumps to the assumption that the researchers are stupid and didn't account for something or other, even if the article says they did. (But it has always been this way and I've given up thinking it will ever stop.)

          A natural experiment does not need to cover the full range. And we definitely have urban populations with excessive particulate capture, due to the meteorological phenomena of temperature inversion.

          Inversion effects occur frequently in big cities ... but also in smaller cities such as:
          Albany, Oregon, United States (Willamette Valley)
          Ashland, Oregon, United States (Rogue Valley)

      Yes, the best hospitals are in urban areas so of course they will be stressed to capacity.

      From TFS:

      "We adjust by population size, hospital beds, number of individuals tested, weather, and socioeconomic and behavioral variables including, but not limited to obesity and smoking. We include a random intercept by state to account for potential correlation in counties within the same state."

      They published their data on Github (https://github.com/wxwx1993/PM_COVID) and the text is available for free (https://projects.iq.harvard.edu/files/covid-pm/files/pm_and_covid_mortality.pdf) but I can't get it to

    • To have a sensible response to the typical lame story getting posted.

    • but in America places with low density populations often don't have a lot of hospitals. Many are well over an hour's drive. So I don't necessarily think that's a factor.

      The researchers seem to have considered density:

      The researchers also conducted six secondary analyses to adjust for factors they felt might compromise the results. For example, because New York state has experienced the most severe coronavirus outbreak in the country and death rates there are five times higher than anywhere else, the res

    • Might explain Detroit. Population density is actually not that high there due to the massive loss of population over the last few decades. But air quality? Ehhh.

    • Well, that can be tested, and according to TFA they did take that into account. There are actually large cities in countries that do take environmental issues serious and hence are suffering from lower pollution and have, unlike Chinese towns, air you can actually see through...

    • While it is often true that high population density area have high pollution levels, that is not always the case.

      In California, two of the most polluted areas are in the huge central valley and in the southern Cal "Inland Empire" where pollutants blown from coastal cities and pollution from farming collide to produce very high pollution levels with moderate to low population density.

      This is not necessarily so true in the United States, which has rigorous air quality standards. Other factors like geography, climate, urban sprawl, and industry matter more.

      It's easy enough to verify by looking at a list of the most densely populated cities in the US and a list of the most air-polluted cities in the US.

      Here are the cities with the worst particulate pollution:
      1 Bakersfield-Delano, CA
      2 Fresno-Madera-Hanford, CA
      3 Fairbanks, AK
      4 San Jose-San Francisco-Oakland, CA
      5 Missoula, MT

          Also, your math is a bit wonky. By my reckoning, $8.8B in FY2019 is less than $10.3B in FY2010. Perhaps you are unclear on the meaning of "all-time high"?

      The problem is much larger in New York and running about a week ahead of California in terms of peaking. That's why New York is having worse outcomes, it's more overwhelmed.

      New York 16,387 cases currently in hospitals of which 4504 are in the ICU.

      California has 2504 patients currently hospitalized of which 1085 are currently in the ICU.

      I don't think this means California patients are sicker than New York patients, I think it means New York has already exceeded the number of ICU beds available, meaning wors
