What’s an infection management? Based on the CDC:
An infection management prevents or stops the unfold of infections in healthcare settings.
Which, arguably, hospitals are. In actual fact, hospitals have administrative buildings for Hospital An infection Management (HIC). Once more the CDC:
The function of the hospital an infection management committee (HICC) is to implement the annual an infection management programme and insurance policies….
Develop a system for figuring out, reporting, analyzing, investigatingand controlling HCAIs
Develop and implement preventive and corrective applications in particular conditions the place an infection hazards exist….
Assessment and replace hospital an infection management insurance policies and proceduresfrom time to time.
HICC shall meet often – as soon as a month and as typically as required.
Since we’re now 924 days / 30 = ~30 months = 30 conferences into the most recent Coronavirus pandemic, one would have anticipated these common month-to-month conferences to have culminated in strong and coherent “politicies and procedures” to stop the airborne transmission of SARS-CoV2. However who am I kidding? Nothing might be farther from the reality.
Listed here are some revealing anecdotes. (I’m together with medical places of work as a result of the hospitals are the hegemonic establishment within the supply of well being care in america, and others might be anticipated to comply with their lead.) For instance:
I’m in a hospital proper now in Iowa astounded that masks are now not required. Completely bonkers.

Why am I in a hospital and nobody is sporting masks

Day 2: no masks I’m going to die right here
— Jessica (@jes_klein_) September 9, 2022
It does. Was not too long ago in Pennsylvania at a hospital and no masks required. At house in New Jersey, masks required in ALL medical services

My 73 12 months previous brother glided by ambulance to an ER in IA cuz he couldn’t breathe. He examined Covid+ & has pneumonia. He was sporting a masks when he bought there & workers informed him he didn’t must, IN A HOSPITAL ER! He mentioned one Dr was masked, however nobody else. WTH is occurring?
— chicky ✍🏻 (@_chicky_little) September 10, 2022
Pressing care final Monday for stomach ache. Masks non-obligatory, individuals coughing within the ready room. Carrying my n95. Mammogram immediately, masks non-obligatory within the hospital system. Tech wore a surgical. I used to be in an n95. Doubtlessly risking my well being for pressing and preventative care.

Dr appt. immediately, massive medical constructing, a number of dr. places of work. Not a single masks on anybody, together with my dr and his nurses. I wore my masks.

On the very least, masks coverage — the primary layer of protection in opposition to aerosol transmission, earlier than air flow — is inconsistent (or inconsistently enforced) throughout jurisdictions in hospitals. So it’s no surprise that Politico writes “Nowhere is protected: Document variety of sufferers contracted Covid within the hospital in January“:
Greater than 3,000 hospitalized sufferers every week in January had caught Covid someday throughout their keep, greater than any level of the pandemic, in line with U.S. authorities information analyzed by POLITICO.
The report surge demonstrates the virulence of the Omicron variant and the way even hospitals, the place an infection management is paramount, offered little refuge.
“Any degree of hospital transmission is regarding,’ mentioned Aaron Milstone, a professor on the Johns Hopkins Bloomberg Faculty of Public Well being who focuses on the prevention of hospital-acquired infections. “The info means that hospitals ought to overview their practices and ensure they’re doing all the things they will to guard sufferers.”
(lol no.) This text appeared in February, 2022. Six HICC conferences later, nothing has modified. Curiously, the problem of whether or not Covid is airborne and if that’s the case, what practices to undertake, blew up method again in 2020. From KHN through the Guardian:
Frontline healthcare staff are locked in a heated dispute with many an infection management specialists and hospital directors over how the novel coronavirus is unfold – and subsequently, what degree of protecting gear is suitable.
At difficulty is the diploma to which the virus is airborne – able to spreading by way of tiny particles lingering within the air – or primarily transmitted by way of massive, faster-falling droplets from, say, a sneeze or cough. This wonky, seemingly semantic debate has a real-world affect on what kind of protecting measures healthcare firms must take to guard sufferers and their staff.
In actual fact, the directors and the an infection management specialists received (as we see from the anecdotes and information above). (See, .e.g., “Some hospitals ask sufferers, guests to take away N95s, citing CDC.”) Why?
On this publish, I’ll present that CDC — maintain onto your hats, right here, of us — rejects airborne tranmission for Hospital An infection Management, certainly for Covid. I’ll then current new information that exhibits how airborne transmission is pervasive in hospitals, reinforcing the info and anecdotes given above. I’ll conclude by speculating why CDC is so sickeningly derelict in its mission to “combat illness and help communities and residents to do the identical.” That is particularly unlucky, for the reason that CDC created the sector:
An infection management (now an infection prevention) in healthcare settings is a comparatively younger medical self-discipline courting again solely to the Nineteen Seventies. Nationwide surveillance for healthcare-associated infections (HAIs) was initiated by the Facilities for Illness Management and Prevention (CDC) in 1970 through the Nationwide Nosocomial Infections Examine (NNIS).
Tne CDC An infection Management Documentation Rejects Aerosol Transmission
I’m going to take a brief journey by way of the CDC’s “An infection Management” web page, on the lookout for what it has to say about airborne transmission. There’s a desk of contents at too proper; I’ve highlighted the areas I’m going to have a look at:
The “How Infections Unfold” web page has a cute little three-tab widget underneath the heading “How Do Infections Happen?”. The tabs are “Supply,” “Prone Particular person,” and “Transmission.” Let’s take a look at every tab in flip.
As you may see, this web page has bullet factors for examples of transmission through fomites, however there’s nothing particular for airborne. Sure, “individuals are one supply of germs,” however there isn’t a indication of how or why. One may think a bullet level for, say, respiration (which creates shared air). However no.
Prone Particular person:
This web page accommodates, no less than for Covid, an outright falsehood. Loads of individuals who have been vaccinated are “vulnerable” to Covid.
Right here, lastly, we get a point out for airborne transmission (though one would have anticipated individuals to have been given for example on web page one). Nevertheless, 1) and jaw-droppingly, Covid is just not talked about (which might lead an harmless reader to imagine that Covid was not airborne). And a couple of) aerosol transmission is just not confined to “lengthy distance” an infection [pounds head on desk]. For those who’re sharing air with an contaminated particular person, that particular person might be six inches, six toes, or six yards away (the latter two relying on the standard of air flow).
Now we flip to the “An infection Management Fundamentals” web page. There are two sections: “Customary Precautions for All Affected person Care”, and “Transmission-Primarily based Precautions”:
Customary Precautions for All Affected person Care:
As I shall present under, 1) the opportunity of Covid an infection in hospitals is pervasive. Therefore, the idea that there are some areas the place PPE is suitable, and a few the place it isn’t, is improper. “Respiratory Hygiene/cough etiquette” 2) is droplet dogma; it ignores airborne transmission through respiration, speaking, singing, and many others.
Transmission-Primarily based Precautions
As soon as once more, 1) there isn’t a point out of Covid. An inexpensive reader, contemplating the salience of Covid on the nightly information or in skilled literature, would conclude that Covid is just not airborne. 2) The concept infectious/vulnerable individuals needs to be given separate rooms flies within the face that the truth that airborne Covid is pervasive within the hospital setting. In the meantime, the concept one would possibly 3) place them in a separate room, however with no HEPA filter, is absurd.
Lastly, we flip to the web page for “Instruments for Healthcare Settings.” (For those who go to the hyperlink, you will notice that there’s nothing particular for airborne transmission)
I’ll take a look at the “device” for “Acute Care,” which I take to cowl hospitals.The “device” is in actual fact a ginormous survey instrument (PDF). Right here is the heading:
“Help within the evaluation of some an infection management applications” this “device” definitely does. However I can guarantee you that there aren’t any entries for “air flow,” “HEPA,” or something helpful for “air.”
There’s an non-obligatory part that mentions “airborne,” I suppose on the idea that just some services have points with airborne transmission of Covid:
So I clicked by way of to the hyperlink given, and located a “Hospital An infection Management Worksheet” from CMMS. Right here is the primary web page, however the remainder has the identical assumptions:
So we discover the identical weaknesses as in “Transmission-Primarily based Precautions” above. 1) Covid is just not talked about. 2) Infectious Individuals are to be positioned in AIIRs (Airborne Isolation An infection Rooms) through which, in part 4.H.6 on the subsequent web page, and contradicting earlier steerage, HEPA filters are mandated, simply not for everybody else. So there’s no considered HEPA filters wherever else, like atypical rooms, or ready rooms, or places of work.
An inexpensive particular person would conclude from studying this guidelines that if a hospital can isolate measles sufferers, it may deal with airborne transmission within the common case. Not so!
So for those who’re on the lookout for a cause why HICCs maintain assembly, month after month, and never accepting that Covid is airborne, or doing something about it, it’s as a result of their hegemonic authority on an infection management, CDC, hasn’t given them any cause to imagine in any other case. For starters.
Airborne Transmission of Covid is Pervasive in Hospitals
From the preprint “The aerobiology of SARS-CoV-2 in UK hospitals and the affect of aerosol producing procedures“:
Aerosol producing procedures (AGPs) appeared significantly dangerous, and insurance policies have restricted their use in all settings. We examined the prevalence of aerosolized SARS-CoV-2 within the rooms of COVID-19 sufferers requiring AGP or supplemental oxygen in comparison with these on room air.
(An instance of an AGP is a tracheotomy. AGPs are the one type of aersols in hospitals that “droplet dogma” permits.) From samples in 219 rooms, ” the biggest air sampling research for SARS-Cov-2 printed so far”:
SARS-CoV-2 viral RNA was detected within the air of hospital rooms of COVID-19 sufferers, and AGPs didn’t seem to affect the chance of viral RNA. Enhanced respiratory safety and applicable an infection prevention and management measures are required to be absolutely and punctiliously applied for all COVID-19 sufferers to cut back threat of aerosol transmission./
Applicable PPE and masks use are important as SARS-CoV-2 is ceaselessly detectable within the airsurrounding constructive sufferers. We imagine our information helps the usage of FFP2/3 medical masks for HCWs caring for COVID-19 sufferers, significantly for these with extended contact in step with HSE tips 15 289 . As we transfer forwards, we should proceed to keep away from oversimplifying the transmission dynamics of SARS-CoV-2 together with into ‘droplet vs aerosol’, as this could result in mounted IPC suggestions and should now recognize that the ‘particular person, place and process’ affect transmission threat. Future suggestions should be guided by rising proof together with ongoing research to establish transmission variations which will happen with new variants of concern
In different phrases, Covid is pervasive, quite like background radiation. Covid actually is airborne!
One asks why? Why would CDC promulgate, and HICCs settle for, apparent falsehoods about airborne transmission, falsehoods which are apparent to anyone who retains up with the literature? A parallel dialogue of CDC’s documentation on air flow in colleges might present a clue.
Every week in the past, I had a 2+ hour name with the senior engineers from CDC-NIOSH who’re liable for the content material of CDC’s air flow pages.(12/25)

ACH (Air Modifications for Hour) is a metric for air flow:
(2) financial implications of placing these ACH numbers on the market would trigger “all hell to interrupt unfastened” if well-meaning individuals throughout the nation undertake them into constructing codes however later discover out they can not implement them with centralized HVAC techniques.

Cash! [slaps forehead]. Why didn’t I consider that? Additionally, in fact, careerism, necessary to the PMC. So right here we’re.
 Covid’s Most Vile Tweet™ remains to be up [pounds head on desk]:
FACT: #COVID19 is NOT airborne.
The #coronavirus is principally transmitted by way of droplets generated when an contaminated particular person coughs, sneezes or speaks.

4,340 quote-tweets, the final one fourteen minutes in the past (as of this writing). So WHO remains to be damaging individuals’s well being, good job,
 America appears, unbelievably, to be superior in masks protections to different “5 Eyes” international locations, just like the UK, Canada, and Australia, if the quantity of outraged tweets is any indicator. In fact, within the US we might have simply given up on outrage altogether, as with Covid typically.
 Within the UK: “Transmission of SARS-CoV-2 to hospitalised sufferers doubtless precipitated roughly a fifth of recognized circumstances of hospitalised COVID-19 within the “first wave” in England, however lower than 1% of all infections in England.”
 The UK an infection management group is as unhealthy and probably worse.
 I recommended the identical in February 2021, based mostly solely on CDC paperwork [lambert preens].
