Abstract

The unanticipated diagnosis of sporadic Creutzfeldt Jakob disease (sCJD) in a patient after previous neurosurgery can lead to difficult decisions on informing contacts. 

A patient developed sCJD three years after neurosurgery. 

There were 29 potential contacts and 26 were contacted. 

Twelve completed a questionnaire. 

The majority of patients wished to know about the contact, to be seen face-to-face, and their main concern was developing the disease, despite verbal and written reassurance that this was unlikely. 

Informing patients of sCJD contact is difficult, and can lead to significant patient anxiety. 

Face-to-face meetings, a helpline, and follow-up can help.

*** Transmission of Creutzfeldt-Jakob disease to a chimpanzee by electrodes contaminated during neurosurgery *** 

Gibbs CJ Jr, Asher DM, Kobrine A, Amyx HL, Sulima MP, Gajdusek DC. 

Laboratory of Central Nervous System Studies, National Institute of Neurological Disorders and Stroke, National Institutes of Health, Bethesda, MD 20892. Stereotactic multicontact electrodes used to probe the cerebral cortex of a middle aged woman with progressive dementia were previously implicated in the accidental transmission of Creutzfeldt-Jakob disease (CJD) to two younger patients. The diagnoses of CJD have been confirmed for all three cases. More than two years after their last use in humans, after three cleanings and repeated sterilisation in ethanol and formaldehyde vapour, the electrodes were implanted in the cortex of a chimpanzee. Eighteen months later the animal became ill with CJD. This finding serves to re-emphasise the potential danger posed by reuse of instruments contaminated with the agents of spongiform encephalopathies, even after scrupulous attempts to clean them.

ALL iatrogenic CJD is, is sporadic CJD, until the iatrogenic event is discovered, traced back, proven, documented in the academic domain, and finally the public domain, which very seldom happens due to lack of trace back efforts, thus, all iatrogeic events stay as sporadic cjd.

THERE should be a mandatory trace out of these patients, and all patients should know, and if they choose not to, so be it, but the victim, patient, and Doctors of all involved must be made aware, and the hospital, this information should be put in some sort of confidential registry (WHERE INSURANCE COMPANIES CANNOT GAIN ACCESS OF SAID PATIENT/VICTIM), where hospitals and doctors can assess and be made aware of iatrogenic TSE Prion event, so that further iatrogenic transmission can hopefully be avoided. IF not, it's all pointless imo. ...terry

CJD TSE Prion Blood Products, iatrogenic transmission, Confucius is confused again, WHAT IF?

''In the 2016 guidance, we recommended that prospective blood donors should be indefinitely deferred if they report having a blood relative with CJD. However, almost all cases reported are sCJD, not a genetic form of CJD. Blood relatives of individuals with sCJD are not at increased risk of developing the disease. The rare genetic forms of CJD (e.g., fCJD, GSS, FFI) share pathophysiological features with sCJD, and the transmission risk by blood components remains theoretical. Consequently, we recommend that establishments may stop asking prospective donors about having blood relatives with CJD.''

CJD TSE Prion Blood Products, iatrogenic transmission, Confucius is confused again, WHAT IF? Docket Number: FDA-2012-D-0307


Confucius is confused again?

''The rare genetic forms of CJD (e.g., fCJD, GSS, FFI) share pathophysiological features with sCJD, and the transmission risk by blood components remains theoretical. Consequently, we recommend that establishments may stop asking prospective donors about having blood relatives with CJD.''

YET, vpspr, sporadic FFI, sporadic GSS, or the pending cases that can't be identified, are all now listed as sporadic CJD.

WHAT IF, sGSS, sFFI, are of an iatrogenic event from iatrogenic donor being from GSS or FFI?

what if vpspr is another strain of a different sporadic CJD, or familial? see;

7Includes 21 (21 from 2019) cases with type determination pending in which the diagnosis of vCJD has been excluded. 

8The sporadic cases include 3831 cases of sporadic Creutzfeldt-Jakob disease (sCJD), 67 cases of Variably Protease-Sensitive Prionopathy (VPSPr) and 35 cases of sporadic Fatal Insomnia (sFI). 

9Total does not include 264 Familial cases diagnosed by blood test only.


under new proposed guidelines ''we recommend that establishments may stop asking prospective donors about having blood relatives with CJD'' (of which i strongly oppose due to the fact sporadic cjd is not a single entity or a spontaneous event, never which have been proven), but under these guidelines, you will miss the vpspr, sgss, and sffi, because they are under sporadic cjd terminology, would you not?

The occurrence of the disease in a patient who had contact with cases of familial C.J.D., but was not genetically related, has been described in Chile (Galvez et al., 1980) and in France (Brown et al., 1979b). In Chile the patient was related by marriage, but with no consanguinity, and had social contact with subsequently affected family members for 13 years before developing the disease. The contact case in France also married into a family in which C.J.D. was prevalent and had close contact with an affected member. In neither instance did the spouse of the non-familial case have the disease. The case described in this report was similarly related to affected family members and social contact had occurred for 20 years prior to developing C.J.D. If contact transmission had occurred, the minimum transmission period would be 11 years. Contact between sporadic cases has not been described and it is remarkable that possible contact transmissions have all been with familial cases. No method of transmission by casual social contact has been suggested.

WHAT IF?

***The occurrence of contact cases raises the possibility that transmission in families may be effected by an unusually virulent strain of the agent.

Sporadic Creutzfeldt-Jakob Disease in a Woman Married Into a Gerstmann-Sträussler-Scheinker Family: An Investigation of Prions Transmission via Microchimerism 

Aušrinė Areškevičiūtė, MSc, Linea Cecilie Melchior, PhD, Helle Broholm, MD, Lars-Henrik Krarup, MD, PhD, Suzanne Granhøj Lindquist, MD, PhD, Peter Johansen, PhD, Neil McKenzie, PhD, Alison Green, PhD, Jørgen Erik Nielsen, MD, PhD, Henning Laursen, Dr.Med, Eva Løbner Lund, MD, PhD Journal of Neuropathology & Experimental Neurology, Volume 77, Issue 8, August 2018, Pages 673–684, https://doi.org/10.1093/jnen/nly043 Published: 07 June 2018

DISCUSSION

This is the first report of presumed sporadic CJD occurring in a person who married into a GSS family. The estimated prevalence of GSS is in the range of 2–5 per 100 million people worldwide, and the annual mortality rate for sCJD in Denmark is 1.46 per 1 million people (31). The population of Denmark consists of 5 740 185 individuals, and there are 2 registered GSS cases that belong to the same family. The Danish GSS family is only the thirty-fourth known GSS family in the world (32). One could assume that the risk for a Danish man with GSS to have a wife or a mother who would develop CJD in her seventies is as high as for any other man. On the basis of the mortality rate for sCJD, and assuming that the incidence of sCJD is the same among married and unmarried people, we could state that 1 man out of 684 932 men has a risk of marrying a woman who would develop CJD. However, in this case, the man a priori had GSS, which means that it would take 1 man out of 684 932 men with GSS for such a pairing to occur. Considering the worldwide rarity of GSS cases, the likelihood for co-occurrence of GSS and sCJD in one family is hence very low and warrants an investigation for the possible transmission of prions routes.

***> However, the VPSPr prion shares the multiplicity of the resPrPD electrophoretic bands with prions from a subset of inherited prion diseases referred to as Gerstmann-Sträussler-Scheinker disease (GSS), prompting the suggestion that VPSPr is the sporadic form of GSS (7,10). Furthermore, the presence of small amounts of sCJD-like 3-band resPrPD has also been signaled in VPSPr (6,11,12).

vpspr, sgss, sffi, TSE, an iatrogenic by-product of gss, ffi, familial type prion disease, what it ???

Greetings Friends, Neighbors, and Colleagues,

vpspr, sgss, sffi, TSE, an iatrogenic by-product of gss, ffi, familial type prion disease, what it ???

Confucius is confused again.

I was just sitting and thinking about why there is no genetic link to some of these TSE prion sGSS, sFFi, and it’s really been working on my brain, and then it hit me today.
what if, vpspr, sgss, sffi, TSE prion disease, was a by-product from iatrogenic gss, ffi, familial type prion disease ???
it could explain the cases of no genetic link to the gss, ffi, familial type prion disease, to the family.
sporadic and familial is a red herring, in my opinion, and underestimation is spot on, due to the crude prehistoric diagnostic procedures and criteria and definition of a prion disease.
I say again, what if, iatrogenic, what if, with all these neurological disorders, with a common denominator that is increasingly showing up in the picture, called the prion.
I urge all scientist to come together here, with this as the utmost of importance about all these neurological disease that are increasingly showing up as a prion mechanism, to put on the front burners, the IATROGENIC aspect and the potential of transmission there from, with diseases/disease??? in question.
by definition, could they be a Transmissible Spongiform Encephalopathy TSE prion type disease, and if so, what are the iatrogenic chances of transmission?
this is very important, and should be at the forefront of research, and if proven, could be a monumental breakthrough in science and battle against the spreading of these disease/diseases.

sporadic CJD, along with new TSE prion disease in humans, of which the young are dying, of which long duration of illness from onset of symptoms to death have been documented, only to have a new name added to the pot of prion disease i.e. sporadic GSS, sporadic FFI, and or VPSPR. I only ponder how a familial type disease could be sporadic with no genetic link to any family member? when the USA is the only documented Country in the world to have documented two different cases of atypical H-type BSE, with one case being called atypical H-G BSE with the G meaning Genetic, with new science now showing that indeed atypical H-type BSE is very possible transmitted to cattle via oral transmission (Prion2014). sporadic CJD and VPSPR have been rising in Canada, USA, and the UK, with the same old excuse, better surveillance. You can only use that excuse for so many years, for so many decades, until one must conclude that CJD TSE prion cases are rising. a 48% incease in CJD in Canada is not just a blip or a reason of better surveillance, it is a mathematical rise in numbers. More and more we are seeing more humans exposed in various circumstance in the Hospital, Medical, Surgical arenas to the TSE Prion disease, and at the same time in North America, more and more humans are becoming exposed to the TSE prion disease via consumption of the TSE prion via deer and elk, cattle, sheep and goats, and for those that are exposed via or consumption, go on to further expose many others via the iatrogenic modes of transmission of the TSE prion disease i.e. friendly fire. I pondered this mode of transmission via the victims of sporadic FFI, sporadic GSS, could this be a iatrogenic event from someone sub-clinical with sFFI or sGSS ? what if?

Familial human prion diseases associated with prion protein mutations Y226X and G131V are transmissible to transgenic mice expressing human prion protein



Furthermore, GSS A117V infected vole brains were able to induce the same disease phenotype in recipient voles within 3–4 months after challenge, proving that a prion agent propagated in the brains of infected animals. These findings imply that brains of GSS patients harbor infectious prions with transmissibility features similar to those found in other human and animal TSEs.

to date, the claim that 85% + of all human TSE Prion are spontaneous/sporadic event that just happens, in my opinion, has never been proven to date. it's a myth, just like the UKBSEnvCJD only there, where only typical c-BSE UK mad cow, is transmissible to humans, and all the rest is old cow disease or old people disease. remember, nvcjd has been documented in very old people as well, plus, it was postulated at the BSE Inquiry that, some farmers are heterozygous for the methionine/valine variant at codon 129, and their lymphoreticular system (LRS) does not contain the high levels of PrPSc found in vCJD. It remains a remote possibility that when older people contract CJD from BSE the resulting phenotype is like sporadic CJD and is distinct from the vCJD phenotype in younger people, and indeed today we find that;

***> In particular the US data do not clearly exclude the possibility of human (sporadic or familial) TSE development due to consumption of venison. 

The Working Group thus recognizes a potential risk to consumers if a TSE would be present in European cervids. It might be prudent considering appropriate measures to reduce such a risk, e.g. excluding tissues such as CNS and lymphoid tissues from the human food chain, which would greatly reduce any potential risk for consumers.. However, it is stressed that currently, no data regarding a risk of TSE infections from cervid products are available. 

snip... 

The tissue distribution of infectivity in CWD‐infected cervids is now known to extend beyond CNS and lymphoid tissues. While the removal of these specific tissues from the food chain would reduce human dietary exposure to infectivity, exclusion from the food chain of the whole carcass of any infected animal would be required to eliminate human dietary exposure. 


 ***Moreover, sporadic disease has never been observed in breeding colonies or primate research laboratories, most notably among hundreds of animals over several decades of study at the National Institutes of Health25, and in nearly twenty older animals continuously housed in our own facility.***

Even if the prevailing view is that sporadic CJD is due to the spontaneous formation of CJD prions, it remains possible that its apparent sporadic nature may, at least in part, result from our limited capacity to identify an environmental origin.

I would kindly like to comment on the Nature Paper, the Lancet reply, and the newspaper articles.

First, I applaud Nature, the Scientist and Authors of the Nature paper, for bringing this important finding to the attention of the public domain, and the media for printing said findings.

Secondly, it seems once again, politics is getting in the way possibly of more important Transmissible Spongiform Encephalopathy TSE Prion scientific findings. findings that could have great implications for human health, and great implications for the medical surgical arena. but apparently, the government peer review process, of the peer review science, tries to intervene again to water down said disturbing findings.

where have we all heard this before? it's been well documented via the BSE Inquiry. have they not learned a lesson from the last time?

we have seen this time and time again in England (and other Country's) with the BSE mad cow TSE Prion debacle.

That 'anonymous' Lancet editorial was disgraceful. The editor, Dick Horton is not a scientist.

The pituitary cadavers were very likely elderly and among them some were on their way to CJD or Alzheimer's. Not a bit unusual. Then the recipients, who got pooled extracts injected from thousands of cadavers, were 100% certain to have been injected with both seeds. No surprise that they got both diseases going after thirty year incubations.

That the UK has a "system in place to assist science journalists" to squash embargoed science reports they find 'alarming' is pathetic.

Sounds like the journalists had it right in the first place: 'Alzheimer's may be a transmissible infection' in The Independent to 'You can catch Alzheimer's' in The Daily Mirror or 'Alzheimer's bombshell' in The Daily Express

if not for the journalist, the layperson would not know about these important findings.

where would we be today with sound science, from where we were 30 years ago, if not for the cloak of secrecy and save the industry at all cost mentality?

when you have a peer review system for science, from which a government constantly circumvents, then you have a problem with science, and humans die.

to date, as far as documented body bag count, with all TSE prion named to date, that count is still relatively low (one was too many in my case, Mom hvCJD), however that changes drastically once the TSE Prion link is made with Alzheimer's, the price of poker goes up drastically.

so, who makes that final decision, and how many more decades do we have to wait?

the iatrogenic mode of transmission of TSE prion, the many routes there from, load factor, threshold from said load factor to sub-clinical disease, to clinical disease, to death, much time is there to spread a TSE Prion to anywhere, but whom, by whom, and when, do we make that final decision to do something about it globally? how many documented body bags does it take? how many more decades do we wait? how many names can we make up for one disease, TSE prion?

Professor Collinge et al, and others, have had troubles in the past with the Government meddling in scientific findings, that might in some way involve industry, never mind human and or animal health.

FOR any government to continue to circumvent science for monetary gain, fear factor, or any reason, shame, shame on you.

in my opinion, it's one of the reasons we are at where we are at to date, with regards to the TSE Prion disease science i.e. money, industry, politics, then comes science, in that order.

greed, corporate, lobbyist there from, and government, must be removed from the peer review process of sound science, it's bad enough having them in the pharmaceutical aspect of healthcare policy making, in my opinion.

my mother died from confirmed hvCJD, and her brother (my uncle) Alzheimer's of some type (no autopsy?). just made a promise, never forget, and never let them forget, before I do.

I kindly wish to remind the public of the past, and a possible future we all hopes never happens again. ...

Alzheimer’s disease and Transmissible Spongiform Encephalopathy prion disease, Iatrogenic, what if ?

Background

Alzheimer’s disease and Transmissible Spongiform Encephalopathy disease have both been around a long time, and was discovered in or around the same time frame, early 1900’s. Both diseases are incurable and debilitating brain disease, that are in the end, 100% fatal, with the incubation/clinical period of the Alzheimer’s disease being longer (most of the time) than the TSE prion disease. Symptoms are very similar, and pathology is very similar.

Methods

Through years of research, as a layperson, of peer review journals, transmission studies, and observations of loved ones and friends that have died from both Alzheimer’s and the TSE prion disease i.e. Heidenhain Variant Creutzfelt Jakob Disease CJD.

Results

I propose that Alzheimer’s is a TSE disease of low dose, slow, and long incubation disease, and that Alzheimer’s is Transmissible, and is a threat to the public via the many Iatrogenic routes and sources. It was said long ago that the only thing that disputes this, is Alzheimer’s disease transmissibility, or the lack of. The likelihood of many victims of Alzheimer’s disease from the many different Iatrogenic routes and modes of transmission as with the TSE prion disease.

Conclusions

There should be a Global Congressional Science round table event set up immediately to address these concerns from the many potential routes and sources of the TSE prion disease, including Alzheimer’s disease, and a emergency global doctrine put into effect to help combat the spread of Alzheimer’s disease via the medical, surgical, dental, tissue, and blood arena’s. All human and animal TSE prion disease, including Alzheimer’s should be made reportable in every state, and Internationally, WITH NO age restrictions. Until a proven method of decontamination and autoclaving is proven, and put forth in use universally, in all hospitals and medical, surgical arena’s, or the TSE prion agent will continue to spread. IF we wait until science and corporate politicians wait until politics lets science _prove_ this once and for all, and set forth regulations there from, we will all be exposed to the TSE Prion agents, if that has not happened already.

#0670: Transmissible Spongiform encephalopathy (TSE) animal and human TSE in North America update October 2009

Authors: T. Singeltary; Bacliff, TX/US

Title: Transmissible Spongiform encephalopathy (TSE) animal and human TSE in North America update October 2009

Body: Background

An update on atypical BSE and other TSE in North America. Please remember, the typical U.K. c-BSE, the atypical l-BSE (BASE), and h-BSE have all been documented in North America, along with the typical scrapie's, and atypical Nor-98 Scrapie, and to date, 2 different strains of CWD, and also TME. All these TSE in different species have been rendered and fed to food producing animals for humans and animals in North America (TSE in cats and dogs ?), and that the trading of these TSEs via animals and products via the USA and Canada has been immense over the years, decades.

Methods

12 years independent research of available data

Results

I propose that the current diagnostic criteria for human TSEs only enhances and helps the spreading of human TSE from the continued belief of the UKBSEnvCJD only theory in 2009. With all the science to date refuting it, to continue to validate this old myth, will only spread this TSE agent through a multitude of potential routes and sources i.e. consumption, medical i.e., surgical, blood, dental, endoscopy, optical, nutritional supplements, cosmetics etc.

Conclusion

I would like to submit a review of past CJD surveillance in the USA, and the urgent need to make all human TSE in the USA a reportable disease, in every state, of every age group, and to make this mandatory immediately without further delay. The ramifications of not doing so will only allow this agent to spread further in the medical, dental, surgical arena's. Restricting the reporting of CJD and or any human TSE is NOT scientific. Iatrogenic CJD knows NO age group, TSE knows no boundaries.

I propose as with Aguzzi, Asante, Collinge, Caughey, Deslys, Dormont, Gibbs, Gajdusek, Ironside, Manuelidis, Marsh, et al and many more, that the world of TSE Transmissible Spongiform Encephalopathy is far from an exact science, but there is enough proven science to date that this myth should be put to rest once and for all, and that we move forward with a new classification for human and animal TSE that would properly identify the infected species, the source species, and then the route.

regarding your article;

Creutzfeldt-Jakob disease: implications for gastroenterology

i belong to several support groups for victims and relatives of CJDs. several years ago i did a survey regarding endoscopy equipment and how many victims of CJDs have had any type of this procedure done. to my surprise, many victims had some kind of endoscopy work done on them. as this may not be a smoking gun, i think it should warrant a 'red flag' of sorts, especially since data now suggests a substantial TSE infectivity in the gut wall of species infected with TSEs. If such transmissions occur, the ramifications of spreading TSEs from endoscopy equipment to the general public would be horrible, and could potential amplify the transmission of TSEs through other surgical procedures in that persons life, due to long incubation and sub-clinical infection. Science to date, has well established transmission of sporadic CJDs with medical/surgical procedures.

Greetings again Professor Farthing and BMJ,

I was curious why my small rebuttal of the article described below was not listed in this month's journal of GUT? I had thought it was going to be published, but I do not have full text access. Will it be published in the future? Regardless, I thought would pass on a more lengthy rebuttal of mine on this topic, vCJD vs sCJDs and endoscopy equipment. I don't expect it to be published, but thought you might find it interesting, i hope you don't mind and hope to hear back from someone on the questions I posed...

Here is my short submission I speak of, lengthy one to follow below that:

Abstract

Prions cause transmissible infectious diseases in humans and animals and have been found to be transmissible by blood transfusion even in the presymptomatic stage. However, the concentration of prions in body fluids such as blood and urine is extremely low; therefore, direct diagnostic tests on such specimens often yield false-negative results. Quantitative preanalytical prion enrichment may significantly improve the sensitivity of prion assays by concentrating trace amounts of prions from large volumes of body fluids. Here, we show that beads conjugated to positively charged peptoids not only captured PrP aggregates from plasma of prion-infected hamsters, but also adsorbed prion infectivity in both the symptomatic and preclinical stages of the disease. Bead absorbed prion infectivity efficiently transmitted disease to transgenic indicator mice. We found that the readout of the peptoidbased misfolded protein assay (MPA) correlates closely with prion infectivity in vivo, thereby validating the MPA as a simple, quantitative, and sensitive surrogate indicator of the presence of prions. The reliable and sensitive detection of prions in plasma will enable a wide variety of applications in basic prion research and diagnostics.

''In the 2016 guidance, we recommended that prospective blood donors should be indefinitely deferred if they report having a blood relative with CJD. However, almost all cases reported are sCJD, not a genetic form of CJD. Blood relatives of individuals with sCJD are not at increased risk of developing the disease. The rare genetic forms of CJD (e.g., fCJD, GSS, FFI) share pathophysiological features with sCJD, and the transmission risk by blood components remains theoretical. Consequently, we recommend that establishments may stop asking prospective donors about having blood relatives with CJD.''

Greetings FDA et al, 

I would again kindly like to comment on Docket Number: FDA-2012-D-0307, Docket Number: FDA-2012-D-0307 Recommendations to Reduce the Possible Risk of Transmission of Creutzfeldt-Jakob Disease and Variant Creutzfeldt-Jakob Disease by Blood and Blood Components; Draft Guidance for Industry Draft Guidance for Industry.

I still believe, that it is extremely dangerous to continue to base the safety of blood from the TSE Prion, by only believing the nvcjd only theory. 

TSE Prion disease have expanded to other species i.e. the camel, and we now know that cwd and scrapie will transmit to pigs by oral routes. 

Chronic Wasting Disease CWD TSE Prion in cervid has exploded across the USA, Canada, Mexico has now clue, Norway, Sweden, Finland, S. Korea, and we know that cwd is detected in the blood of cervid. CWD TSE Prion is highly infectious, and the risk factors from blood there from are very real.

we also know that all iatrogenic CJD is, is sporadic CJD, until the iatrogenic event is discovered, traced back, proven, documented in the academic domain, and finally the public domain, which very seldom happens due to lack of trace back efforts, thus, all iatrogeic events stay as sporadic cjd.

with the blood of cervid and cwd tse prion being detected there from, the science showing that cwd zoonotic potential is now real, the many different strains of cwd to date, with no real factor of how many different strains there are, with science now showing that indeed BSE, Scrapie, and CWD, both typical and atypical strains, showing scientific links to sporadic cjd, and that cwd in humans would would NOT look like nvcjd, but science shows that it would look like sporadic cjd, therefore, iatrogenic cjd from human cwd exposure is very real threat, i find these weakening of rules for blood risk factors from all the different strains of sporadic cjd very worrisome, especially now that officials are classifying vpspr, sgss, sffi, as sporadic cjd cases. we have no clue whether or not these are from iatrogenic events or not. this will be a foolish move if we put once again, corporate interest over human and animal health, but does not surprise me. 

THIS will be very dangerous, and a foolish move for people who need blood, and for the medical and surgical theaters, and humans there from, and simply are not based on sound science imo, but are based on corporate greed. 

WE KNOW now that the real statistics on human TSE Prion IS NOT one in a million, but data now shows that sporadic CJD, 85%+ of all human TSE Prion, the read statistics now show that those figures are one in 5,000. and sporadic cjd is NOT a single strain, but many, many, different strains, and the routes and sources are simply unknown. 

NO WHERE IN SCIENCE LITERATURE HAS THE SPONTANEOUS CJD EVER BEEN PROVEN, without route and source, a happenstance of bad luck, this is simply wishful thinking$ 

TO weaken, instead of enhance and strengthen the risk of sporadic CJD tse prion from blood products by this Docket Number FDA-2012-D-0307 Recommendations, will only enhance the risk of TSE Prion to hemophiliacs, the medical and surgical arenas around the globe

yes, human tse prion are now 1 in 5,000. let that sink in. 

MONDAY, JANUARY 20, 2020
sporadic CJD one in a million, FAKE NEWS PEOPLE!
this myth has been incorrect for decades, and had been stated as such by a few, but again, the media is too lazy to do it's job and print the facts.
