Chronic Wasting Disease (CWD): The Start of a Zombie Apocalypse???

From its triggering factors to the growing
concerns surrounding it, here’s what you need to know about chronic wasting disease:
Today’s video was requested by Random Stuff 252. If you have any other topics you’d like to

disease that mainly affects cervids, members of the deer family, including moose, caribou,
elk, white-tailed deer and mule deer. It’s always fatal and, so far, there are
no treatments or vaccines to protect these animals from it. CWD has received a significant amount of attention
in the media, with some believing it could bring about a ‘zombie apocalypse’ if it
spreads to humans. In fact, the behavioral changes associated
with CWD are among the reasons it has come to be known as zombie deer disease. So far, there isn’t any evidence of transmission
from cervids to humans. Yet, recent scientific research seems to indicate
that might change at some point in the future. Number 7 Discovery
Chronic wasting disease was first identified in northeastern Colorado, in 1967, in a herd
of captive mule deer. It wasn’t until the early 80s that CWD was
discovered in wild elk and mule deer, both in Colorado and Wyoming. At the time, an endemic zone for the disease
was established in those states. From that point on CWD steadily spread throughout
wild and captive populations. There are still several elk herds in Colorado
and one white-tailed herd in Wisconsin that remain under state quarantine. According to a retroactive study, infected
deer were exported in the 80s from Denver to Toronto Zoo. This may have been the first contact that
Canada had with the disease. Number 6 Where Is It Located? As of 2019, the Centers for Disease Control
and Prevention have reported cases of CWD in 251 counties and 24 states in the US. There have also been reports from Alberta
and Saskatchewan, in Canada. So far, the only European country where CWD
has been detected is Norway. The origin of contamination in the Scandinavian
country is unknown. The disease has also been reported in South
Korea, where the source was infected deer imported for farming in the late 90s. Number 5 Factors
Just like the mad cow disease, scrapie, in goats and sheep or Creutzfeldt-Jakobs disease
in humans, CWD is a transmissible spongiform encephalopathy. The main factor behind its onset is believed
to be a prion, which is a misfolded form of a normal protein, called the prion protein. Proteins are like building blocks in the body
and they provide a large number of important biological functions. They’re, in turn, composed of many smaller
building blocks called amino acids, which fold onto each other into 3D structures. The normal prion protein, called PrPC, is
commonly found in the brain and spinal cord. Its’ not known what causes them to misfold,
but the resulting form is much more resistant to unfolding and breaking down and it can
convert other normally folded prion protein. These misfolded forms, called PrPSc, accumulate
in the brain to a point that it can cause death. Examined under a microscope, the cerebral
cortex shows many holes, which make it resemble a sponge, hence the name spongiform. Another theory is that CWD isn’t caused
by prions but by a bacterium called Spiroplasma. Biologist Frank Bastian, the author of the
theory, has reportedly succeeded in growing the bacterium from the brains of CWD-infected
animals. He argues that the prion formation is the
body’s way of defending against the bacterium, but not the root cause. Other scientists haven’t been able to reproduce
his results, which is why most are still in favor of the prion theory. Number 4 Symptoms
A diagnosis of CWD is typically established through necropsy and testing. Even though the disease can be somewhat determined
in a laboratory setting, there’s currently no commercially feasible diagnostic test to
be used on live animals. Since many animals die early in the course
of the disease, it becomes harder to establish post-mortem if CWD was the cause. One of the techniques that may be effective
is taking fluids from cervids suspected of being affected and incubating them in genetically
modified mice. However, there are certain ethical and scalability
issues that would argue against this method. CWD has only been observed in non-human animals,
but its symptoms certainly have zombie-like characteristics. Deer stricken by it exhibit dramatic weight
loss, stumbling, lack of coordination and walking in set patterns. Drooling, teeth grinding, tremors and lowering
of the head have also been observed. They no longer fear people and decrease their
interactions with other animals. There are certain problems with identifying
infected deer by these symptoms alone, as some of them also occur with malnutrition
and other diseases. Moreover, CWD can be present without any symptoms
for years after the animals become infected. Number 3 How Will It Kill You? According to the research conducted so far
and considering the evolutionary state the disease is in, there’s no strong evidence
that it’s transmissible to humans. However, that doesn’t mean that CWD prions
can’t jump the species barrier, at some point. CWD is progressive, always fatal and doesn’t
presently have any form of treatment. Experiments indicate that the CWD prion can
infect squirrel monkeys and laboratory mice, which carry several human genes. The most worrying aspect, regarding infecting
humans, is that it has been transmitted to macaques, monkeys that are genetically closer
to humans than any other animal. A study, conducted by a team of Canadian and
German scientists, showed that, out of five monkeys fed infected white-tail deer meat,
three became infected with CWD. This was the first instance of the disease
spreading to primates through meat consumption and the basis of concern for a potential ‘zombie
apocalypse’. The monkeys were also infected when the tainted
material was inserted directly in their brains. Chronic waste disease wouldn’t be the first
transmissible spongiform encephalopathy that evolved to affect humans as this happened
previously with mad cow disease. According to Mark Zabel, associate director
at the Prion Research Center at Colorado State University, the prions that cause CWD are
flexible and able to adopt many shapes with relative ease. He claims that there are reasons to suspect
the disease could, at one point, pass to humans because it’s still evolving. Additionally, certain studies seem to indicate
that researchers can artificially alter the evolution of CWD prions, whether in animal
models or test tubes, so that they cause human proteins to misfold. Since such evolution is possible in a laboratory
setting, it might occur in nature as well, under the right circumstances. Number 2 Transmission
Another frightening aspect about CWD is the multiple ways in which it can be transmitted. Between animals the disease is spread through
urine, feces, blood or saliva either through direct contact or indirectly via contaminated
food, water or soil. The prions cling tightly to soil particles
and remain in the environment for a long time. Even after an animal dies and decomposes,
it still may leave behind an infectious environmental reservoir of CWD. As an avian scavenger, the American crow can
become a carrier for the disease. It’s been discovered that the prions are
still viable after they pass through the crow’s digestive tract. Considering the crow’s range, population
density and longevity, this creates ample opportunities for the spreading of CWD. In certain elk populations, there was also
high rate of transmission from mother to fetus. Number 1 How to Survive? Even though there isn’t strong evidence
for CWD in humans, precautionary measures are still advised for hunters and people who
eat deer meat. If they are hunting in-or if the meat comes
from an area known for CWD, they should get the meat tested. However, these tests aren’t available in
every state and they might be applied differently, depending on the region. A negative result doesn’t guarantee an individual
animal isn’t infected, but it does reduce the chances. Information about testing is available in
many states and people should check if it is recommended or required in their area. If the test is positive for CWD, the overall
consensus is don’t eat the meat. Hunters should avoid shooting deer and elk
that are acting strangely. They should also take extra precaution when
field dressing the deer. It’s recommended that they wear rubber or
latex gloves and minimize handling tissues from the brain and spinal cord. Thanks for watching! Do you think chronic waste disease will bring

  1. Oh no! It cOuld mutAte sO we shOuLd be wOrried. I'd be way more worried of diseases that can spread to humans mutating. Deer aren't eating eachother but people think we will? Well shit, what if the flu mutates and makes us eat eachother? Lmfao

  2. no i don't, i think our minds are to advanced for this to effect us totally, it may give us a case of what would be considered mental illness. what if in discovering CWD , we've found the grand dad of all mental illness

  3. Why do you number your mini docs. It’s not a top ten vid. I mean I get the need for organization but the number+title is unnecessary, just desperate the parts by title and drop the numbers

  4. Can't believe people are actually believing this thing to be a start if the zombie apocolypse… This thing's been known to us for decades, why NOW are we suddenly freaking out about it?

  5. My opinion is that if they keep testing this in animals that are close to us in genode codes were pretty much setting us up for it to take is form through our species and i hope we find a cure if true

  6. Worried about a zombie apocalypse occurring from this strange disease? Cool let's implant the disease straight into the animal which is genetically closest to us just to give it a little evolutionary push along the timescale. 🙂 good one scientists

  7. imagine having an apocalypse scenario from a infected deer shitting and pissing on the land some dumb ass grows crops only to sell them to people at a low low price, thats probably god up there laughing or someone from china fucking everyone up again

  8. Siberian people ates meat of deers, we should tell them to stop eating it, because the disease may transmit to humans.

  9. In the video, it says that the monkey who ate an infected meat became infected too. They are also primates, therefore if human accidentally ate that kind of meat, the CWD may transmit to humans. Siberian people shoulf stop eating those meats, they should eat poultries and Porks instead.

  10. It’s reminiscent of Mad cow and CJK disease. Not zombies. It’s may be related to prions. I haven’t watched the whole video yet, that may be postulated or referred to.
    Frightening situation no matter the cause

  11. It’s not “documented” as transmissible to humans. Before HIV there was SIV (simian). It’s only a matter of time and exposure that’s likely to change that.

    That should be a huge red flag for anybody that may use carcasses for animal feed as CJK/Mad cow showed us!!!

    Man this drives me crazy!! Avoid venison tartare or beef/venison carpaccio for the time being folks.
    Most proteins are heat-liable (denatured or destroyed by heat) but some proteins/prions structure can be heat-stable at certain temperatures, requiring autoclave pressures and temps to denature or “kill” as is true for many bacterial spores (A.K.A. thermophilic or “affinity for” heat/ heat tolerant)

  12. Well time to load up on meds, ammo, food, water. Time to get guns. Time to make a group before it comes and time to train to shoot. Anything else I miss?

  13. Why does this make me think of plague inc. As if our world is a simulation, but a massive simulation either controlled by thousands of aliens or by one alien with many simulators.

  14. I am here to gather information on the greatest threat to my way of life. If you can help me find more sources of info on CWD and its effects on deer hunting, please reply with a link. Thanks

  15. That means as soon as this zombie apocalypse happens drink quick revive,speed cola,juggernog,stamin up,and double tap,get ur gobblegums and raygun and fight

  16. I'm a hunter gatherer….n I've seen instances of white tails n mules doing shit that deer don't do in WV n PA……whereas you can approach n pet….they find a creek n drown their selves….etc

  17. cwd and mad cow is related and mad cow did spread to humans. so its just a matter of time before humans get it.

  18. Scientists or doctors need to develop a vaccine or cure fast but first they should develop treatment for it

  19. We know for a fact there are other forms of life in the universe: viruses,fungus,parasites,bacteria etc. We know for a fact that there are animals,insects who got hijacked by a parasite that now controls their brains and movements.Over 60% of life on earth is actually made of microorganism .We can't live without them they literally generate oxygen in the atmosphere. In fact, we have trillions of microorganisms living inside our bodies at any given time.Is it not possible that one day earth gets hit by an asteroid containing some of sort of microorganisms that are capable to infect humans and literally turn them into sort of a ''zombies''

  20. Zechariah 14:12
    and this shall be plague with which the lord will strike all the peoples that wage war on Jerusalem:their flesh will rot while their standing on their feet,their eyes will rot in their sockets,and their tounges will rot in their mouths

  21. Hey I got a good idea. Lets take the disease and keep forcing it into other animals that have similar dna as humans and see if we can speed up the evolution of it. 🤦‍♂️🤦‍♂️🤦‍♂️

  22. what is wrong with you people this is not going to happen God is looking after us all but worst case scenario there are only one type of people that would survive a zombie apocalypse I will give you a hint the name starts with g okay screw it I'm just going to tell you GAMERS

  23. Alright, alright, alright. The deers are not dead when they catch this. It causes warts, tumors, and sores. They're just sick. All of you guys think they are dead.

    If anything, rabies would start the apocalypse.

  24. Dr. James Kroll sets the record straight regarding CWD: LINK: ** A MUST SEE video!!

  25. I think it can, I mean if chronic wasting disease can be transferred to deer to humans, yes it can be transferred to humans.

  26. Pretty sure if we survived Scrapie and BSE aka Mad Cow outbreaks which ARE transmitted to humans so deer with CWD that is NOT transmitted to humans I dont think the walking dead is around the corner anytime soon

  27. Saw a deer running in circles before it jumped into the front of my car today. Looked pretty skinny. This could explain why it was downtown running around.

  28. Ok but your saying it’s not able to transmit to humans then how will it evolve if it’s been around for decades ? It hasn’t evolved. Ans probably won’t. I just think this video is trying to scare us.
