Just upgraded to paid. I’ve followed Dr Prasad on YouTube since the beginning of Covid and so glad I found him then! Sensible Medicine is a must to subscribe to also!

This is a great article. I love that the gloves are off.

Vinay's gloves have been off for a while...beginning after the article where he called masking "bioplausible" which is the same as calling geocentricity of the solar system "astroplausible". Many things are plausible but masking was known not to work at the time, plausible or not. But since then, he has mostly been spot on.

Broadway producers spent fortunes fitting out their theaters with HEPA filters, stage managers gave up their offices for the covid police, and for every actual working person, they hired a back up from an "underrepresented marginalized group" who stood around and basically did nothing. then they made a bunch of white men take classes where they learned that only white men can have "privilege." it really went far in destroying backstage morale.

Though if someone sits in an office in a building without operable windows, wouldn't it make more sense to have a mechanical system that has more outdoor air exchanges and filters more air so aerosolized airborne virions don't accumulate? Such an HVAC system would serve the entire building. Sure, someone who works in this building will eventually go somewhere else without such a HVAC system, but still it's all the sealed "sick" buildings that create a lot of unhealthy indoor environments, not only for airborne viruses.

Anyway, someone should do a study with netty pots for respiratory viruses for children that use that daily versus children who don't use them at all. Which, if either, arm has more respiratory infections. This may sound like a joke, but if post-infection, viruses replicate in the nasopharynx, a netty pot with a saline solution may reduce those viral loads.

Mainstream media is propaganda and I heartily with putting quotes on public health “experts”

"Joseph Allen" must have stock in the HEPA company. they can make the air better easily- stop putting crap and poisons into it! over turning the EO that protects Glyphosate would be a first good step

Here’s his X bio: Prof at Harvard; Exposure and Risk Science; Direct Harvard #HealthyBuildings Program; Coauthor of HEALTHY BUILDINGS w/ HBS Prof Macomber. He definitely has a reason to push filters.

These studies are important, and more are needed. But a negative result from one intervention—such as a single HEPA filter in a nursing-home room—should not be interpreted as evidence that ventilation and air filtration are unimportant.

COVID-19 spreads predominantly through airborne respiratory particles, particularly in crowded, poorly ventilated indoor spaces. Early restaurant outbreaks showed that infections closely followed seating location and airflow patterns. Outdoor transmission is much less common because exhaled particles are rapidly diluted and dispersed.

The effectiveness of ventilation and filtration depends on the room size, occupancy, airflow pattern, amount of outdoor air introduced and indoor air exhausted, and the capacity and placement of the filtration device. An undersized HEPA filter may accomplish little in a large or crowded room, but that does not negate the value of properly designed ventilation and filtration systems.

Kindergartens are also unusually intense close-contact environments: children interact closely, touch their faces and noses, and readily spread multiple viruses. Handwashing may modestly reduce respiratory illnesses, but it is not a substitute for clean air when dealing with a predominantly airborne virus.

A target of at least five air changes per hour may be needed. We should not write off ventilation because one or two limited interventions failed to demonstrate protection. Further study. Fresher air.

Well said ! I am glad you pointed that out In addition the good doctor is not only showing his biases but also how to think or read something that he favors and put forth

Friendly perspective from the "Commies" in Sweden. We never had this discusdion at all, only masks and distancing, no vacvine duscussion or mandate still 85-90% uptake and only boosters for the very old.

Our CDC only talked about flattening the curve. It was clear that everyone will get covid and it would be endemic from reasonably early

Irish Bearcat's avatar

Outdoor transmission and “common” should not be used in the same sentence. Outdoor transmission is almost impossible and those who wore or continue to wear masks outdoors deserve mockery.

Jesse Wilson's avatar

I'm mocking them right now. In my mind. No one can stop me.

We didn't stop testing for flu in South Africa. Surveillance showed a steep drop in flu at the height of COVID. My theory is that influenza arrives in the Southern hemisphere each year in a plane. When no planes were flying here we wouldn't get influenza. Nobody believed me though. They thought it was all about COVID measures

The Diagnostic Detective's avatar

While it currently lacks RCT level evidence. There is a strong argument for installing carbon dioxide monitors in South African classrooms as levels correlate strongly with infection rates for TB. If the level starts rising all the windows must be opened. An RCT would be challenging and likely nobody would ever fund it. In that case you are stuck with a possible cheap intervention but no likelihood of RCT level evidence.

I have a more basic question. Has anybody ever demonstrated that respiratory illnesses are communicable via airborne particles? There was apparently a lot of interest in this following the great influenza in 1917-19. I have read that there were many studies that exposed people to close contact with others suffering from colds and flu during the 10-15 year period following the epidemic and the results were uniformly negative. They even went as far as to transfer nasal and tracheal secretions from people that were ill to those that were not. Has this commonly accepted concept concerning communicability ever been scientifically verified?

Jesse Wilson's avatar

From a layman's perspective, there seems no question about the existence of viruses. They're manufactured easily now with CRISPER technology, there's photos of them, and I suspect more evidence besides. What makes you think they literally don't exist? I know there was a guy who promoted terrain theory at the same time Pasteur was hypothesizing bacterial parthenogenesis, and "lost" I guess. But the idea that we become sick because our "terrain" is in bad shape doesn't contradict germ theory, seems to me it's a perfect compliment. So I wonder what makes so many people reject germ theory at least with regard to viruses.

Ernest N. Curtis's avatar

I don't reject germ theory. Over decades of medical practice I have seen many infections due to bacteria that can be seen and cultured routinely. Technically, one cannot say that viruses don't exist. The proper statement is that there has never been any scientifically valid evidence that viruses exist. They have never been physically or biochemically isolated or shown to grow in tissue culture. Viruses are said to be biologically inert particles consisting of nucleic acids (DNA or RNA) contained within a protein coat that are ubiquitous and spring to life when they are able to penetrate a living cell. The biological probability of such particles seems unlikely and has never been shown to be true by conventional scientific standards. The best source on this is a short book titled "A Farewell to Virology" by Dr. Mark Bailey. I have searched much of the literature on virology and have not found any scientifically valid argument refuting the claims in his book. I would be happy to reproduce selected quotes from his book in another comment if this would be of interest to you.

My knowledge of CRISPER technology is pretty minimal, but from what I have read, it is primarily concerned with alteration of existing DNA genes and/or eliminating genes felt to cause certain diseases. If someone can explain in simple terms how a lab could create a viral genome, enclose it in a specific protein coat, so it could then hang around until it can find and penetrate a living cell, I would be glad to consider it.

It's inferred from a tuberculosis transmission experiment. https://publichealth.jhu.edu/2020/the-experiment-that-proved-airborne-disease-transmission

but I do not think that it has been tested on other sorts. However, given how the minks on mink farms ... animals kept in cages ... managed to transmit covid to one another, I think it is a pretty good inference. But doing the animal experiment ought to be easy enough, so somebody should do one.

Ernest N. Curtis's avatar

Thank you for the response to my question and the link to the TB article. As you correctly state, the conclusions are inferred from the observations. At least the TB bacillus can be seen and, presumably, cultured. I have not seen the mink study. One problem with virology is that it seems to be an entirely inferential discipline based on serologic evidence and misapplication of the laboratory technique called PCR. I suspect that the mink study probably relied on these same techniques by which covid "infection" was attributed to a large number of people (called cases) that were asymptomatic. Over a 40 career I had trusted what I had been taught in medical school regarding viruses and infectious disease. The anomalies of the covid episode raised many questions in my mind concerning what I "knew" about viral diseases and, thus far, I have seen little evidence to corroborate the standard paradigm.

Laura Creighton's avatar

I am not talking about a mink study, except that I think somebody should do one. The mink evidence comes from people who are raising mink, and had all their caged animals become infected. If not by airborne transmission, then how did it happen, since they were caged separately and couldn't bite, lick, or groom each other?

Graphite 🇨🇦's avatar

How was the 'Covid'infection in the minks determined? By PCR test??? 🤣

Laura Creighton's avatar

There are blood tests and tests of mouth swabs.

Graphite 🇨🇦's avatar

Yes, very important point. Thanks for bringing it up 👍

Vinay, despite how pandering this is about to sound, I'm going to say it anyway: I think you fucking rock, man. You, as well as Dr John and others who are tangential to sensible medicine, calm my nervous system and keep me out of stupid thought bubbles I do not want to be a part of or get captured in. I also love how you don't trust Public Health officials, which I haven't for decades; I would not trust the CDC to file my fingernails. I so appreciate you and your mission, at least what I see as your mission, to give people the information that encourages them to be engaged, informed, and smarter. Thank you.

For what its worth we have one per room. Prior to that when they changed the ac filters in the attic they were filthy. Now they are not and with several shedding dogs the filters do a good job of keeping hair out of main AC. I think if you are going to use them at scale for true protection the air flow needs to be studied . If the schools had the same neg air flow the isolation rooms in hospitals have outcomes would be different but at an impossible to consider expense.

I heard that INFLUENZA cases decreased during COVID since Americans were no longer hugging everyone they met. But immediately when we went back to work, etc., all the hugging and kissing started again because unlike other cultures such as Japan we can't just nod and say hello because we're so miserable so lonely so fat

Influenza cases declined dramatically during covid because everything was classified as Covid.

Celeste's avatar

They stopped testing for the flu which resulted in no positive flu test results. Magic disappearing act. The flu was essentially rebranded as covid. It’s absurd to think the flu disappeared because people were wearing masks (mostly beneath their noses and never for pictures) and/or standing 6 feet apart.

Use a daily saline or xylitol spray to keep viruses from replicating in the nasal mucosa.

I have followed your work for nearly a decade with tredmendous respect. Please drop the f-bombs --language that really is beneath you.

Your name is a common household word in my friendship circle of metabolically fit 70-something women.

Yes, spend the money on JERF (just eat real food) to improve school lunches.
