BREAKING NEWS: SIMULATED SUNLIGHT KILLS COVID - BUY SUNLAMPS, THROW AWAY MASKS

in Deep Dives4 years ago

The study, titled “Estimated Inactivation of Coronaviruses by Solar Radiation,” looked at how effective UVB rays had been at inactivating coronavirus at various locations around the world.

The new study also suggests that shelter-in-place orders and similar lockdown plans could be counterproductive for anyone sharing a roof with multiple people.

“Healthy people outdoors receiving sunlight could have been exposed to lower viral dose with more chances for mounting an efficient immune response,” it said.

ABSTRACT

Using a model developed for estimating solar inactivation of viruses of biodefense concerns, we calculated the expected inactivation of SARS-CoV-2 virus, cause of COVID-19 pandemic, by artificial UVC and by solar ultraviolet radiation in several cities of the world during different times of the year. The UV sensitivity estimated here for SARS-CoV-2 is compared with those reported for other ssRNA viruses, including influenza A virus. The results indicate that SARS-CoV-2 aerosolized from infected patients and deposited on surfaces could remain infectious outdoors for considerable time during the winter in many temperate-zone cities, with continued risk for re-aerosolization and human infection. Conversely, the presented data indicate that SARS-CoV-2 should be inactivated relatively fast (faster than influenza A) during summer in many populous cities of the world, indicating that sunlight should have a role in the occurrence, spread rate, and duration of coronavirus pandemics.

Estimated time for inactivation of SARS-Co V-2 virus Table 2 shows reported solar virucidal flux at solar noon together with the estimated minutes of sunlight exposure needed at various populous North American metropolitan areas to inactivate 90% of SARS-CoV-2. The (+) sign in Table 2 indicates that 99% of SARS-CoV-2 may be inactivated within the two hours period around solar noon during summer in most US cities located south of Latitude 43oN. Also 99% of the virus will be inactivated during two hours midday in several cities south of latitude 35oN in Fall, but only Miami and Houston will receive enough solar radiation to inactivate 99% of the virus in spring. During winter, most cities will not receive enough solar radiation to produce 90% viral inactivation during 2-hours midday exposure (underlined values in Table 2).

The objective of the present study was to evaluate the influence of simulated sunlight and suspension medium on the persistence of SARS-CoV-2 on surfaces and provide data needed to inform assessment of the exposure risk associated with contaminated outdoor surfaces.

The light spectrum was designed to represent natural sunlight, specifically in the ultraviolet (UV) range (280–400 nm), and closely matched model spectra from the National Center for Atmospheric Research’s (NCAR) tropospheric ultraviolet and visible (TUV) radiation model in this range [15] (Figure 2). A previous study demonstrated that light in the UVA portion of the spectrum (315–400 nm) did not damage SARS-CoV-1 at doses similar to those used in the present study [16]. Therefore, the integrated irradiance in the UVB portion of the spectrum (280–315 nm) was utilized to quantify exposure. The intensity of the light was controlled through the use of neutral density filters and adjustment of the power supply to the lamp. Three different intensity levels, approximating integrated UVB irradiance levels for different times of day and year, were utilized in testing (Figure 2 and Figure 3). Spectra produced by the solar simulator were measured immediately outside of the chamber window using a spectroradiometer (OL756; Gooch & Housego) equipped with a 2-inch diameter integrating sphere light receptor (IS-270; Gooch & Housego), and corrected for transmission losses through the window.

In contrast to simulated sunlight, no significant decay was observed in darkness over the 60-minute test duration, which is consistent with previously published data with both SARS-CoV-2 and SARS-CoV-1 [4, 5, 9, 20]. van Doremalen et al [4] reported half-lives of 5.6 and 6.8 hours for SARS-CoV-2 on nonporous stainless steel and plastic surfaces, respectively, under indoor conditions, or approximately 18 to 23 hours for a 90% reduction in infectivity. Chan et al [9] reported that it took 3–5 days to lose 90% of infectivity of SARS-CoV-1 dried on a surface under indoor conditions.

The present study provides the first evidence that sunlight may rapidly inactivate SARS-CoV-2 on surfaces, suggesting that surface persistence, and subsequently exposure risk, may vary significantly between indoor and outdoor environments. However, in order to fully assess the risk of exposure in outdoor environments, information on the viral load present on surfaces, the transfer efficiency of virus from those surfaces upon contact, and the amount of virus needed to cause infection are also needed.

I'm afraid that rights are mostly granted by mob democracy. A man's right to life and liberty can be taken away by any group larger, better armed and/or better organized than his. The mechanism is and always has been concerned citizens fighting against the status quo for the betterment of the status quo.

Thank you so much for sharing, great post

Also, TIL you got a Roku channel and I just so happen to have a Roku TV. Nice!

Let me know if it works, I haven't received any feedback yet.

thank you very much for the advice and excellent article, have a nice weekend

I picked up one of these handy contraptions when things were just getting started. I forget if it is UVB but it was advertised as being germicidal.

I primarily use it go disinfect facemasks rather than throw them away after one use but I really don't like having to wear one if social distance is maintained. Find myself becoming slightly winded from my grocery expeditions.

It seems like these would be much less invasive than forcing everyone to wear muzzles.

I read an article a while back that said commercial grade home sun lamps don't have enough uvb to kill the virus.

FAKE NEWS.

Lol, I hate to tell you this but if sunlight could substantially wipe out the virus we'd all be toast from the rays cooking us, that 's because the UV rays that can destroy viruses aren't the type for prolonged exposure to humans. They do have these types of lights and they are used in some hospital settings, now being implemented on some airplanes but not while humans are sitting there, you can't point one at you at home to get a tan...not without serious consequences. (I wrote all that in a round about way because I am to lazy to go look it all up right now)

You're thinking of UV-C light.

The study cited was testing UV-B light.

Does not matter. No UV-C, A, or B is considered safe for prolonged exposure, meaning the kind of exposure that would be needed to kill the virus. Now you could turn on a sun lamp when you leave the house for HOURS and there is potential for reduction to elimination depending upon time, strength, type used but you need to shut it off while you are home for any prolonged period of time.

HERE'S THE SOLUTION. INSTEAD OF PERMANENTLY CLOSING MY BUSINESS AND FIRING ALL MY EMPLOYEES. INSTEAD OF THAT. PERHAPS I COULD CLEAR THE BUILDING EVERY HOUR ON THE HOUR FOR 10 MINUTES WHILE FLOODING THE PLACE WITH UV-C LIGHTS.

You mean like what they are currently doing in China to disinfect trains and stations?....lighting them up? Not a bad idea at all evidently but like I mentioned before the bus is empty of people. There's nothing wrong with using these lights except you have to be cautious of human exposure or prolonged human exposure.

No, omnipotence and omniscience also allows for restraint.

Where's the counter-balance? When GOD($) goes on "vacation" who takes over? Wouldn't the entire world simply freeze?

GOD($) controls every breeze, every snowflake, every chirp of every bird.

GOD($) has a 100% monopoly on power and creativity.

You might argue that GOD($) "gives" us some of that power.

But GOD($) knows what we'll do with that power BEFORE GOD($) ever gave it to us.

How is that any different than programing a robot?

Can an engineer "give" a "robot" creativity?

Can a "self-driving" car have "free-will"?

If you knew that giving a child a certain toy would lead to them choking themselves, if you knew that, with your omniscience, if you knew that would happen, but you gave them that toy anyway, WOULD THAT MAKE YOU A MURDERER?

Marijuana is less dangerous than alcohol. Nixon found it politically advantageous to ratchet up drug enforcement because most of his detractors happened to be hippies and minorities (who also just happened to enjoy this harmless pastime). Nixon's policies demonstrated broad public support for expanding police powers, and "drug enforcement" is the reason "no knock" warrants were invented in the first place - And even though, as you mentioned, rich whites tend to favor cocaine, "crack" (which is exactly the same substance in another form, like flour and bread) carries much higher penalties (and it just so happens to be more popular among poor populations) - -
