I wanted to protect my family, my tenants, and my employees so I spent the last two months researching the reason the COVID-19 became a pandemic. The first thing I noticed was that the virus killed a lot of people in areas where the air was filthy. On the other hand, few died in areas where the air was clean. I soon learned that the 1918 Spanish Flu pandemic that killed ~50 million people was tied to polluted air so I continued to research. I ended up writing a long article that I would now like to share with this group. https://dumaguete-studio-apartments.com/prevent-covid-19-infection I hope it helps... David
The answer is simple, the Chinese knew that polluted air caused the spread of the virus so they ordered the shutdown of all coal-fired electric plants and other air-polluting operations. The air above Beijing got became very clear and this clean air was picked up by US Satellites. https://www.npr.org/sections/goatsa...-been-cleaner-during-the-coronavirus-outbreak
It is a very long article to say that people who live in places with polluted air have more risk of pulmonary disease (!), either as a direct result of the noxious particles in the air or a greater risk from catching lung (and other) diseases because their lung (and other) tissue is damaged and/or their general health is impaired. It impacts on the lungs, heart, blood vessels and almost every, if not all, organs and tissues of the body - it even impacts on pregnancy. I have to say that this is a very well known fact by scientists and non-scientists alike - probably just about the most well-known fact. As for reductions in air-pollution in China, I think you confuse 'cause and effect' - air pollution dropped principally because factories closed. Of course if we had no air pollution then fewer people would die of any illness or disease linked to air pollution.
The attached article discusses air temperature and relative humidity. This may help explain why the Philippines and some other countries are not as hard hit by the virus as other countries. https://blog.sensibo.com/2020/04/07...SeKOUusEqlsm2c-AgH7WKOPEYUe_5A-jb-kfdpHXXdrHc
Not disqualifying the OP correlation findings. Healthier people seems to have a far better chance surviving this infection and pollution is not healthy. But cracks in winny the pooh's lockdown on ccp virus bullshit numbers reports seems to occur. Outbreaks are occuring all over china also, the dangerous ccp censor is still trying to keep this a secret downplaying all infection numbers. Also Beijing is hit, i am sure.
