DHS Study Sheds Light on COVID-19 Best Practices

by: Anon

In March and April, the Department of Homeland Security studied the effect of environmental conditions — temperature, light and humidity — on the COVID-19 virus. [1]

Bill Bryant, director of Science and Technology, presented the findings on April 23, 2020. [2], [3], [4] “Our most striking observation to date is the powerful effect that solar light appears to have on killing the virus — on surfaces and in the air. Increasing the temperature and humidity, or both, is generally less favorable to the virus.”

DHS studied virus survival on non-porous hard surfaces such as door handles and stainless steel. They also studied its survival in aerosols — saliva droplets from sneezes and coughs.

Virus survival is measured in terms of half-life: the interval in which half the virus particles are eliminated.

Tests on non-porous surfaces:

· (A) On indoor surfaces with 20% (low) humidity and no sunlight, virus survived the longest, with a half-life of 18 hours.

· (B) Raising the humidity to 80% cut the half-life by two-thirds to 6 hours.

· (C) Then raising the temperature to 95°F cut half-life to 1 hour.

· (D) On surfaces in summer-like conditions of 70-75°F, 80% humidity and bright sunlight, half-life was sharply reduced to only 2 minutes. Virus was eliminated over 500 times faster compared with (A).

The same tests were done on respiratory droplets.

· (E) Half-life in aerosols, in 20% humidity, 70-75°F, and no sunlight, was around 60 minutes. That is, virus in aerosols disappeared 18 times faster than on indoor surfaces under conditions (A).

· (F) Adding summer-like sunlight cut the half-life down to about 1.5 minutes. Sunlight eliminated the virus 40 times faster than (E), and 720 times faster than (A).

The virus survives best on surfaces in dry indoor conditions. It does not survive as well in saliva droplets. And it dies the quickest in the presence of direct sunlight under these conditions. Summarizing the aerosol data, Mr. Bryan said, “in a room, 70 to 75 degrees, 20 percent humidity, low humidity, the half-life is about an hour. But you get outside, and it cuts down to a minute and a half. A very significant difference when it gets hit with UV rays. And, Mr. President, while there are many unknown links in the COVID-19 transmission chain, we believe these trends can support practical decision making to lower the risks associated with the virus.”

The data has stunning implications. It suggests that Americans worried about virus can benefit from spending more time outdoors in sunlight, humidity, and warm summer temperatures. It suggests that outdoor mask mandates and prohibition of normal summertime outdoor activities could promote the spread of virus, not contain it.

Mr. Bryan then discussed experiments on disinfecting environmental surfaces. “We’re also testing disinfectants readily available. We’ve tested bleach and isopropyl alcohol on the virus, specifically in saliva or in respiratory fluids. And I can tell you that bleach will kill the virus in five minutes; isopropyl alcohol will kill the virus in 30 seconds, and that’s with no manipulation, no rubbing — just spraying it on and letting it go. If you rub it, it goes away even faster. We’re also looking at other disinfectants, specifically looking at the COVID-19 virus in saliva.”

· Heat and Humidity Suppress COVID-19 indoors and outdoors

· Move Activities Outside – sunlight impedes virus transmission

· Commonly Available Disinfectants (Bleach & Isopropyl Alcohol) work to kill the virus. (This third point depicting a spray bottle was obviously about disinfecting hard surfaces.)

The mainstream media spun the DHS presentation immediately. [5], [6] The study contradicted the globalists’ goal of forcing heathy individuals to stay indoors and refrain from normal summer activities, with a short-term goal of maximizing the death count and a long-term goal of justifying fraud-laden universal vote-by-mail this autumn.

One article assaulted Mr. Bryan’s integrity by calling him a “non-scientist” and attacking his military background.[7] The writer begs to differ: military background is relevant in defense against biological agents. DHS’s innovative multidisciplinary approach examines problems from all sides, whereas medical research limits itself to a narrow silo where the answer is always more expensive and profitable drugs.

The media instantly jumped on President Trump’s subsequent questions to Mr. Bryan and the task force doctors. The President asked two separate questions [9]:

(1) Whether light could somehow be introduced into the body to kill virus (it can, according to a new treatment protocol) [8]

(2) Whether research should investigate other potential ways to kill virus using disinfectants.

In light of DHS’s “best practices” slide, Mr. Trump’s disinfectant question was obviously about cleaning environmental surfaces. The press maliciously conflated the two separate questions to imply that the President wanted people injected with bleach. By twisting the President’s remarks, plainly intended to spur outside-the-box thinking, the media managed to almost completely sweep this groundbreaking research under the rug.

The First Amendment enshrines our right to discuss these matters freely and to form our own opinions on research that could have a bearing on our health.

In light of the data, shouldn’t we be spending plenty of time outside in sunlight, humidity, and heat, without a mask?

9. THE PRESIDENT: So I asked Bill a question that probably some of you are thinking of, if you’re totally into that world, which I find to be very interesting. So, supposing we hit the body with a tremendous — whether it’s ultraviolet or just very powerful light — and I think you said that that hasn’t been checked, but you’re going to test it. And then I said, supposing you brought the light inside the body, which you can do either through the skin or in some other way, and I think you said you’re going to test that too. It sounds interesting. ACTING UNDER SECRETARY BRYAN: We’ll get to the right folks who could. THE PRESIDENT: Right. And then I see the disinfectant, where it knocks it out in a minute. One minute. And is there a way we can do something like that, by injection inside or almost a cleaning. Because you see it gets in the lungs and it does a tremendous number on the lungs. So it would be interesting to check that. So, that, you’re going to have to use medical doctors with. But it sounds — it sounds interesting to me. So we’ll see. But the whole concept of the light, the way it kills it in one minute, that’s — that’s pretty powerful.
