Wind is very important, indeed. - Today wind speed

18(20/22) km/h 10m(100/250) above ground, this will

bring the dirt to Phayao, upper Nan Province and

Chiang Rai. - Sorry.

The next problem might be the north eastern winds.

Exposure to air pollution and COVID-19 mortality in the United States (Updated April 5, 2020)

 

Results: We found that an increase of only 1 μg/m3 in PM2.5 is associated with a 15% increase in the COVID-19 death rate, 95% confidence interval (CI) (5%, 25%). Results are statistically significant and robust to secondary and sensitivity analyses.

Conclusions:

A small increase in long-term exposure to PM2.5 leads to a large increase in COVID-19 death rate, with the magnitude of increase 20 times that observed for PM2.5 and all-cause mortality. The study results underscore the importance of continuing to enforce existing air pollution regulations to protect human health both during and after the COVID-19 crisis. The data and code are publicly available.

Of course. it's only numbers. At a first glance.

There is a self-evident(?)/central message:

“This study provides evidence that counties that have more polluted air will experience higher risks of death
for Covid-19,” said Francesca Dominici, a professor of biostatistics at Harvard who led the study.

Counties with higher pollution levels, Dr. Dominici said, “will be the ones that will have higher numbers of
hospitalizations,
higher numbers of deaths and where many of the resources should be concentrated.”

 

In the same direction leads (but only concerning pneumonia 2014-2017 in China)

https://journals.plos.org/plosmedicine/article?id=10.1371/journal.pmed.1003010

'Our findings suggest that there are significant short-term associations between ambient PM levels and
increased hospital admissions for pneumonia in Chinese adults.'

The study was published: December 31, 2019

I would really appreciate any serious ideas:

Why are the PM2.5-numbers at/near

hospitals up north since some weeks

so extremely high? - Thanks.

11:00 - Today the hospitals measure again. Easterly

wind improves the situation in some parts.
