What Have You Got Against A Mask?

1/9 What Have You Got Against A Mask? In a black and white photograph, a black woman wearing a white duckbill respirator, gazes deep into your soul. Her eyes tell you that .... The simple act of wearing a respirator (KN95, N95, or better) can save your life, if they're used properly and every time you are in a public place / outside your home. Wearing a mask helps prevent transmission of airborne viruses such as SARS-CoV-2, RSV, influenza, and more. Despite profit-based claims otherwise, we are still in a global COVID pandemic. Mask up to protect yourself and others from illness, disability... What Have You Got Against We, The People? A DELTA plane landing on their words that have killed thousand. Disabled hundreds of thousands, and destroyed us all. We are writing on behalf of Delta Air Lines to the Centers for Disease Control and Prevention (CDC) to reconsider the current guideline for 10 days of isolation in fully vaccinated individuals who experience breakthrough COVID-19 infections... We propose a 5-day isolation from symptom onset for those who experience a breakthrough infection. Delta Airlines to CDC Director, Dec. 2021 THIS IS TO ENRAGE YOU.

This may be the biggest news of the decade. Completely overshadowed by shenanigans in the White House.

It looks like H5N1 reinfections are entirely possible. This means that our farms are going to be a never-ending circulating pump of H5N1.

This. Is. Not. Good.

/1 But reinfections suggest that the virus, called H5N1, could circulate on farms indefinitely, finding opportunities to evolve into a more dangerous form — a “high-risk” scenario, said Louise Moncla, an evolutionary biologist at the University of Pennsylvania. “You could easily end up with endemically circulating H5 in dairy herds without symptoms, obscuring rapid or easy detection,” Dr. Moncla said. How long can our luck go on?

We now have Bobcats with the one mutation that we really don't want to see.

The PB2 E627K mutation.

If you are taking public transport like in NYC? Mask up.

Pretty cool Master's Thesis for Biology - on bioaerosols like SARS-COV-2.

Set up a prototype aerosol sampler?

And find it in 52.9% of the samples in Beijing Railway Station and 44.4% at Beijing Subway Station.

/1 The subway station selected for this experiment was Xidan Subway Station, a major subway station on Lines 1 and 2 in Beijing and serves as an important subway transit hub. The passenger flow of the station is expected to be around 7,000 – 12,000 during rush hours and less than 7,000 during non rush-hours. A total of 27 samples have been collected, with the first 10 collected around 9-10am in the morning or 3-4pm in the afternoon, which is considered non-rush hour and 17 collected during the rush hour period. Sampling was collected for 17 weeks in total, not necessarily consecutively taking ...
Bioaerosol Sampling in the Exit Area of Beijing Railway Station. BC500 was placed near the exit area of the Beijing Railway Station where passenger flow is expected to be the largest. Beijing Railway Station is one of the oldest train stations in Beijing with a large passenger flow that is around 60,000 passengers per day. The bioaerosol sampling device in this scenario is placed at the exit area of the train station, where passenger flow is relatively higher, ensuring better chances of sample collection. However, passenger flow, unlike the subway station is not divided into rush / non-rus... Never mind this.

"Firstly, the high positive rate highlights the potential for airborne transmission of these viruses in crowded public areas"

Definitely do not flag this to anyone in a big city looking to ban masks.

Definitely do not do that with this new study. The findings of the experiments conducted in this thesis indicate that viruses including SARS-CoV-2 and influenza are not only present but also potentially widespread in these public spaces, which has several important implications. Firstly, the high positive rate highlights the potential for airborne transmission of these viruses in crowded public areas. This is consistent with existing literature that suggests densely populated environments with limited ventilation can facilitate the spread of respiratory viruses. The detection of multiple pathogens reinforces the importance of considerin...

Ozone. A pollutant no matter where it is - outdoors or indoors.

#DYK that indoor inhalation is 25% to 60% of total intake? Per Weschler?

iaqscience.lbl.gov/increases-ozone

#DYK that MOST indoor ozone comes from OUTDOORS? Per Weschler?

pmc.ncbi.nlm.nih.gov/articles/PMC16…

Truly worried?

🧵 Accounting for the differences between indoor and outdoor air ozone concentrations, Weschler [6] has estimated that indoor exposures to ozone are typically 45% to 75% of total exposures. Because breathing rates are lower when people are indoors, the indoor inhalation intake of ozone is typically 25% to 60% of total ozone intake. These estimates may be low for the population most affected by ozone—infants, the elderly, and those with respiratory and cardiovascular disease. Consequently, if there is no threshold concentration for the health effects of ozone, or if the threshold is low, roughl...
Although there are indoor sources of ozone, in most buildings indoor ozone has been transported from outdoors (Weschler 2000). Indoor ozone concentrations track outdoor concentrations with a slight time lag that depends on the air exchange rate. Ozone is removed by indoor surfaces as well as by gas-phase reactions, and hence, indoor concentrations tend to be smaller than co-occurring outdoor levels. If you are TRULY worried, you should be focused on eliminating ozone, right?

You would be slipping into people's threads and sharing these cheap DIY activated carbon builds, right?

ACH ACPH - Air Exchanges per Hour.

An important topic since way before 2020, but given fresh vigor with our collective interest in clean air. Not just disease free air, but VOC, PFA, microplastic, mold, UFP, PM 1, PM 2.5, etc.

The outside air will infiltrate inside.

Ozone. FAR-UVC. GUV222.

New preprint.

Room with 1.3 ACH (1.3 h-1) (like your home).

1 lamp was good enough to disinfect room. Produced "negligible" ozone. -0.62 ±0.03 ppb

Even with 4x the needed strength? 6.98 ±0.24 ppb. -0.62 ±0.03
We refer to this room as “Room A.” Room A has no window, and is connected via a door to a large, open plan lounge area in the office suite. This Lounge space was used for baseline measurements. The door between Room A and the Lounge was closed during experiments. The air exchange rate in Room A was measured using the CO2 tracer method [33] with portable CO2 sensors (Aranet4) to be 1.3 h-1 (Supplementary Information). Room A and the lounge are carpeted. Room A is equipped with a conference table, a small wooden desk, and chairs. It also has room lighting and a wall-mounted computer monitor. ...
Tests with a single fixture used a Lumenlabs Lumenizer 300 (Lumenlabs, Shanghai, China) and tests with four fixtures used Lumenlabs Zone devices. Each of these fixtures contains three optically filtered KrCl bulbs with a peak emission wavelength of 222 nm. The optical output of a Lumenizer fixture is 55 mW and the optical output of a single Zone fixture is 190 mW. According to the manufacturer, each Lumenizer 300 fixture is capable of disinfecting a 4m x 4m room; therefore, a single Lumenizer 300 unit would be normally deployed for a room the size of Room A in this study. That is to say, th... The conclusion? One lamp does not impact the air quality.

With 4 times OVERKILL.

Under 10 ppb. Secondary organic aerosols (SOA)? minor increases in particulate matter (16% increase particulate matter, 10 % increase in particle number count). We have observed the effects of far-UVC on indoor ozone and particulate matter under conditions of real-world application in a small conference room with low ventilation. We find that a single Lumenizer 300 far-UVC lamp, specified by the manufacturer to be sufficient for disinfection of the space, does not negatively impact indoor air quality through net generation of O3 or PM under the conditions of our experiment. Far-UVC may be a valuable component of a multilayer approach to reduce the risk of transmission of respiratory viruses, used in combination with ventilation and other interventi...

Not sure what is going on with @HealthcareGlob1 - they sure seem to have it out for @NukitToBeSure.

They blocked me after I pointed out that they were incorrect. I could care less about being blocked.

I do care they did not address the issues I raised. 🧵 They retweeted this tweet from DisabledDoctor, which has numerous issues.

1. FARUVC has been safely
& extensively tested on the eyes. There are a rather large number of studies on the topic.

2. FARUVC will not cause AQ issues, besides a Yup. Not even considering the fact that she recommends using her far-UV devices in ways that are possibly unsafe (pointed at face as they are untested on eyes and in poorly ventilated indoor spaces where it is likely it will cause air quality issues leading to or exacerbating respiratory problems). She's harming vulnerable people while profiting off of them and she seems to give no fucks while somehow managing to get people to aggressively support her when she is (fairly) criticized.

The CDC decides if you, the other patients, and your HCWs wear surgical masks, N95s, or no masks in hospitals. Where you go to get better, not sicker.

They obey the HICPAC, who voted for NO MASKS - based primarily on one study to justify it.

The study is Radonovitch (2019). It was done from 2011-2015.

Back then, most everyone, including the authors 👇, thought respiratory viruses were primarily transmitted by actual large droplets. Respiratory viruses are primarily transmitted by large droplets.

@propublica - opening the window is not the only solution for formaldehyde.

In fact, formaldehyde is the most abundant VOC from fires. Like wildfires and wood burning stoves.

It is also found in tobacco smoke and automobile exhaust.

/1

acp.copernicus.org/articles/21/18…. x.com/propublica/sta…Formaldehyde (HCHO) is one of the most abundant non-methane volatile organic compounds (VOCs) emitted by fires. HCHO also undergoes chemical production and loss as a fire plume ages, and it can be an important oxidant precursor. In this study, we
Formaldehyde is also a byproduct of combustion. When burning natural gas, kerosene, gasoline, wood, or tobacco, formaldehyde is produced. Automobile exhaust is a common source of formaldehyde in our environment. Tobacco smoking in the home is another source of the chemical in the indoor environment. A good rule of thumb? Open the window and smell smoke or auto exhaust? Formaldehyde.

Also, windows are at the edges of a room.

What if you want to hurry the process along and clean the air in the middle of the room, too?

@Raw_Farm has been forced to halt all sales of their "Bird Flu Milk" by the California state, because their dairy cows have #H5N1.

The Cali gov can say, "Told you so."

latimes.com/environment/st… This comes two days ago after Mark McAfee swore up and down that his cows were not infected.

latimes.com/environment/st…McAfee said he does not think the virus is present in his herd. The tests that the state's agriculture department have been regularly conducting twice a week on his bulk milk have been negative. In addition, he noted, a test taken on Monday also showed no virus. In addition, he said, he monitors each cow at his farms with a high- tech device - made by the Austrian company smaXtec - which sits in a cow's udder and sends real-time information about the animal's body temperature, milk acidity, etc.

Bhattacharya is an unserious person for a serious position.

A quick break down of his comments.

I thought the beginning where they share a snide laugh about LongCovid spoke volumes.

Then, Bhattacharyra (or Bhattie for short), talks about 100 million missed cancer screenings. 100 million cancer screenings missed - this is a serious issue.

But what Bhattacharyra does not mention is the WHY.
