The Epidemic
What To Look For In A Face Mask, According To Science[fivethirtyeight.com, via Naked Capitalism 6-25-20]
Different researchers have set up devices that spray tiny droplets at fabric and then measured how much of it comes through the other side, while also measuring air flow to determine breathability. What they’ve found is that it’s less about the type of fabric — cotton, linen, silk — and more about the quality of fabric, according to Segal. Higher quality fabrics have a tighter weave and thicker thread that do a better job of blocking droplets from passing through.
But you also want the fabric to be breathable, according to Taher Saif, a mechanical engineer at the University of Illinois who has been researching face mask material. Saif said if breath can’t get through the mask, it will find another way out, allowing respiratory droplets to spread.
.... Segal offered a rule of thumb: hold the material up to a bright light. “Look at the light coming through the fabric,” Segal said. “If it outlines individual fibers and you can see the light through fabric, it’s probably not as effective. The less of that you can see, the better the filter.”“Data map reveals the 23% of US counties that are currently seeing an uncontrollable growth in COVID-19 – as new model predicts Phoenix alone could see 28,000 new infections a DAY by July 18” [Daily Mail, via Naked Capitalism Water Cooler 6-26-20]
“Twenty three percent of counties across the United States are now seeing an uncontrollable growth in new COVID-19 infections, according to a data map... Phoenix could see 28,000 new cases a day by July 18.... large parts of the South and Southwest are showing an ‘epidemic trend’ or ‘spreading trend’ for new coronavirus infections…. Of the 3,141 counties across the country, 745 are currently experiencing an epidemic outbreak and 1,232 are seeing spreading trends, according to the data map. Nearly 670 counties are currently seeing a controlled trend in new coronavirus cases. According to the map, the entire state of Arizona is seeing either epidemic or spreading trends. ”A link to the map
The unintended impact of COVID-19 on cancer
[The Hill, via Naked Capitalism 6-21-20]
In April 2020, the IQVIA Institute for Human Data Science published a report that shined a light on the unintended impact of our response to the treat of COVID-19. According to the report, it is estimated that the delay in 22 million cancer screening tests will result in an increased risk of delayed or missed diagnoses for 80,000 patients.
