BREAKING! Forget About Airborne Transmissions, University of Edinburgh Study Shows That SARS-CoV-2 Can Even Be Transmitted By Winds!
When Thailand Medical News
first proposed in 2020 that the SARS-CoV-2 could even be transmitted by winds, certain garbage Western ‘experts’ mocked our hypothesis and then when again when we warned in mid-April 2021 that the SARS-CoV-2 coronavirus was also evolving such that its conformational structures were changing to adapt to more severe environmental conditions and also the ability to ‘glide more easily through air’, we once again ridiculed by Western ‘experts’. The latter has been proven to be true as various studies have shown that the coronavirus has gone through conformational structural changes since the emergence of the Delta variant and has even evolved more in terms of the various Omicron variants.
It should be noted that Chinese researchers and health authorities in June 2022 had also warned winds could help carry the SARS-CoV-2 across borders!
A new study by researchers from the University of Edinburgh-UK has found evidence that the SARS-CoV-2 coronavirus can also be transmitted by winds!
It is already known that aerosolized SARS COV-2 is viable for at least 3-5 hours of not more depending on the environmental conditions. Aerosols can rapidly become droplet nuclei and be carried long distances by wind before they settle.
The study team hence investigated the possibility of identifying wind-assisted transmission of COVID-19.
COVID-19 cases/100,000 population was calculated for hotspots and surrounding areas. Daily wind direction/speed data for hotspots was collated. Seven-day rolling averages of COVID-19 cases/100,000 population was plotted against wind direction/speed to compare case rate trends in hotspots, upwind and downwind areas. Within 14 days of the wind blowing into an area, case rate trends downwind differed from that of the hotspot. The difference compared to the hotspot could be an increase, plateau, or a slower decrease. The study findings suggest that viral particles carried by the wind can lead to an increase in infections downwind.
The study findings were published on a preprint server: Research Square, and is currently being peer reviewed. https://www.researchsquare.com/article/rs-1741081/v1
In one study conducted in the United States, 46% of patients with COVID-19 disease reported known contacts, indicating that infection could spread via less apparent routes. Evidence of the aerosol-mediated transmission of viral infections, including COVID-19, is increasing. Aerosol transmission of SARS-CoV-2 was reported inside a quarantine facili
ty, and an outbreak in a cruise ship reinforces the possibility of aerosol transmission. https://www.cdc.gov/mmwr/volumes/69/wr/mm6926e3.htm
Studies have also showed that under experimental conditions, the aerosolized SARS-CoV-2 was viable for three hours in 65% relative humidity. Another experimental study reported that the viability of aerosolized virus in artificial saliva was up to five hours. Because SARS-CoV-2 was viable up to the tested duration, the actual period of its viability remains unclear. Therefore, it is possible that viral particles carried by wind could cause an increase in COVID-19 cases downwind.
The study team tested whether COVID-19 infections soar following wind change. COVID-19 hotspots in the United Kingdom (UK) during the initial pandemic phase were identified. Case trends in hotspots were analyzed upwind and downwind within 14 days of wind change.
In the study, the wind was southwesterly in West Midlands until mid-March and variable after that. Data from Wolverhampton, Birmingham, Dudley, Walsall, Sandwell, and Coventry were combined into the West Midlands area. The northeasterly wind blew twice during March 26 – 31 and April 17 – 23, 2020. Data from Worcestershire and Warwickshire were combined (henceforth WosWar) for analysis.
Interestingly, COVID-19 cases peaked on April 3, 2020, in West Midlands and WosWar and declined after that, a trend similar to the UK. Case rates plateaued in WosWar from April 7, 12 days post first wind change. The decrease in COVID-19 cases was slower in WosWar than in West Midlands after the second wind change.
However, in contrast, case trends in Staffordshire (north to and upwind of West Midlands) were distinct. Case rates peaked on April 4 before dropping and increased steadily from April 8, after the first wind change.
The study team next investigated a known hotspot, Sheffield, northeast of Staffordshire.
Here, a northeasterly wind blew into Staffordshire thrice from March – April 2020.
It was found that COVID-19 cases increased from April 8, 12 days post first wind change and peaked on April 15. Cases rates increased from April 18, after the second wind change. A third wind change began during this surge. In Sheffield, case rates declined from April 30, while case trends remained plateaued until May 5 in Staffordshire. Notably, COVID-19 cases soared sharply after testing for essential workers was mandated on April 23.
It should be noted that Northeasterly winds blew twice between March 26 to 31 and April 18 to 22, traveling across London into Surrey. COVID-19 cases peaked between April 5 and 8 in London and April 6 in Surrey. A steady increase in COVID-19 cases commenced 13 days after the first wind change from April 8, plateauing until April 17. Cases in Surrey and London continued to decline after the second wind change.
In another scenario, a southerly wind blew from London during March 23 – 25 to the north into Buckinghamshire, Essex, and Hertfordshire (BEH). This wind change coincided with the increasing case rate in BEH. Cases peaked in BEH on April 9 before dropping. Another southerly wind blew between April 4 and 7, and the rate of decline was slower 12 days after April 16 and plateaued between April 24 and 29.
Also, a southerly (April 4, 5) and southwesterly (April 7) wind blew into Northumberland from County Durham and Tyne and Wear. COVID-19 cases increased significantly in Northumberland eight days after the wind change, and meanwhile, cases in County Durham and Tyne and Wear were already peaked and began to drop. Eight days after the southerly wind, cases in Northumberland increased while those in County Durham and Tyne and Wear decreased.
The research findings indicated an increase in COVID-19 cases downwind following a wind change, probably due to wind-assisted spread/transmission of SARS-CoV-2 particles from a hotspot to adjacent regions.
The study team believed that places beyond those analyzed in this investigation might also have an effect.
The study findings show the possibility of SARS-CoV-2 transmission by wind has critical implications for preventing its spread, and more urgent research is required to address the aerosol transmission of the virus.
