Now we are getting some coverage on ways to reduce viral load – no doubt scams will exist – hopefully govt comes in with guidelines and stamp of approval – article notes a banana test! https://www.discovermagazine.com/health/uv-light-wands-are-supposed-to-kill-viruses-but-do-they-really-work
“If you want to test a light you’ve already bought, try the (yes, really) banana test. Place the light over a green banana for 15 minutes. Any UV-C lamp will turn the skin brown. But here’s the caveat: The banana test works on a broad wavelength, and doesn’t specifically target a wavelength of 260 nanometers. But it will tell you if the bulb works and whether it’s actually emitting UV-C light, which are both important questions, says Armani.”
“On July 29, JetBlue Airways revealed the Honeywell UV Cabin System, a robot the size of a beverage cart with arms that extend over the top of seats to sweep the cabin and treat aircraft surfaces. It can disinfect the entire cabin in roughly 10 minutes.
Troutbeck, a historic retreat set on 250 acres in New York’s Hudson Valley, upgraded all of the resort’s HVAC systems with a new HEPA filtration system that includes UV light for extra germ-fighting.
New York’s public transportation system, the Metropolitan Transportation Authority, worked with Columbia University to test UV light in vehicles and other fixed locations, such as break rooms and operation centers.”
“UVC light damages the virus’s RNA so that it is no longer able to reproduce and infect. It can also damage the protein that coats the virus, disabling it to attach to a host cell.
Typical germicidal UVC light kills viruses at a wavelength of 254 nanometers. However, all viruses are different and some respond to shorter or longer wavelengths. They also require a different UV dose, which is measured by light intensity and exposure time.”

Not the best of report as school starts – https://jamanetwork.com/journals/jamapediatrics/fullarticle/2768952
“Our analyses suggest children younger than 5 years with mild to moderate COVID-19 have high amounts of SARS-CoV-2 viral RNA in their nasopharynx compared with older children and adults. Our study is limited to detection of viral nucleic acid, rather than infectious virus, although SARS-CoV-2 pediatric studies reported a correlation between higher nucleic acid levels and the ability to culture infectious virus.5 Thus, young children can potentially be important drivers of SARS-CoV-2 spread in the general population, as has been demonstrated with respiratory syncytial virus, where children with high viral loads are more likely to transmit”
Hopefully not just opening schools without creating more ventilation – modify HVAC, open windows, wear mask – low hanging fruit….it can be done as noted in this article – https://www.cnbc.com/2020/08/04/how-to-stay-safe-while-flying-and-staying-in-hotels-during-a-pandemic.html
His big concern is not the flying part as noted – over 50% of the air is fresh and HVAC has HEPA filters – as noted before a 12hour flight with an infected person and NO other person got infected – shows it is possible to create an environment to limit the spread. We should cost effectively be able to create schools and public places similar to an airplane environment if not better as one can open a window!
Another good death day for the US (542) – seems so strange how sporadic the death reporting is – low death days no news but then report 1500+ day its all over the press. India leads the world at 803
Texas leads the US at 138 deaths
Once again a decent amount of death in an unassigned county (19) – we are trying to figure out what this means. Majority of death on the border counties Cameron and Hidalgo.
Cameron had a surge of confirmation of 2545.
Harris county continues to confirm but the deaths are limited keeping the fatality rate 1% or less.
Confirmations are not going away worldwide – the original countries are not taking confirmations to zero….Japan rising 1280 a day….The only country keeping confirmations low is S. Korea – still not zero.
