The Deadliest Virus on Earth

[@tux75]

It has been suggested that the vampire myth originated from people infected with rabies. Since rabies causes light hypersensitivity, hydrophobia, aggression, and occasional biting, it fits the narrative of a typical vampire who goes out at night, is scared of holy water, and sometimes bites people. It’s interesting to think about anyway!

[@Balin_James]

That also explains why the myth of vampires includes creating other vampires through biting sometimes! That’s cool, I honestly never drew that connection

[@christiandaniellloyd]

When I was 19, an erratic bat that crashed with almost every object around entered in my house, and when I tried to grab the creature to throw it back outside, it bit me. My mother was highly concerned about what just happened, she seemed almost hysteric and I of course thought she was overreacting. She took me to a clinic that same night and made me take the anti-rabies vaccine, the first shot of many that I had to take in order complete the treatment. Reading afterwards about the awful and agonizing death that rabies patients suffer when they are left unattended, I am very grateful to my mother for her urgency and don't wanna think too much about what would have happened if she hadn't been around to act so quickly and decidedly. Most probably I would have forgotten about the bite the next day and would have died in the next few months. She saved my life.

I’m so sorry you had to go through that. Feel free to ignore this, I’m just curious.

Humans don’t usually show aggression through biting. I thought that the ‘furious’ part of the virus was just general aggression/agitation of the victim. Is that not the case?

I remember reading that one of the most-affected parts of the brain by rabies is actually the amygdala, which controls a person's fear response.

@@hoihoipoipoi This isn't true. Rabies is definitely slow with an incubation period of 2 - 3 months according to the WHO and "weeks to months" according to the CDC. You can get the vaccine any time within that incubation period. The full vaccination course (with 5 doses) takes 14 days, and while a few people have survived without the full 5 doses (take this part with a grain of salt because I don't fully remember it), it's generally best to get all the shots. Rabies may kill people quickly after symptoms present, but it's more likely than not that they were actually exposed to the virus months in advance. Secondly, if we're referring to the same person, they were using an experimental treatment called the Milwaukee Protocol to try to treat rabies. While that procedure worked on the patient, it has only worked that single time, while failing on 25 other patients it was attempted on. Due to this low success rate and high cost, it's more likely that the success was a fluke due to outside factors, and so it's generally not recommended now if I remember correctly.

Two months ago, I thought I was going to die from rabies. I was on vacation in Morocco and attempted to pet a dog on the beach. It bit me and ran off. "Oh, that guy is angry, lol." - I thought. I had never heard that rabies was fatal, so I just ignored the subject, returned to my home country, and resumed my normal life. Ten days later, I was on my way to work and began to feel an itchy sensation in the area of the bite, accompanied by a strange headache. I searched for my symptoms online and discovered that rabies could be the cause. I then researched rabies further and watched a video that explained everything. That marked the beginning of the worst ten days of my life. Then, I immediately sought medical assistance. I went to the ER and described my symptoms. The doctors were concerned, as rabies rates in Morocco are high. Unfortunately, the rabies vaccine was only available at one hospital in the entire city, so I had to wait an entire day to receive it. That night, I didn't sleep, work, or eat I went to get my vaccine, fully aware that if rabies was the cause of my symptoms, it might be too late. The doctor who administered the vaccine appeared worried as well, though she tried to hide it. I received two doses of the vaccine and immunoglobulin to boost my immune system. Now, it was a matter of waiting. Unfortunately, my symptoms worsened. I started to feel dizzy and very anxious, both symptoms of rabies. However, I also experienced panic attacks. So I wasn't sure if I had rabies or if I was just having a panic attack. I was terrified, so I created my will online. I recorded a video for my mom, my girlfriend, and my two best friends, explaining why I thought I was going to die and wish them the best. The next day, I developed a fever (which I later learned was also a side effect of the vaccine). I couldn't help but cry. I wasn't afraid of dying; I was afraid of dying from rabies. The following day, I visited a rabies specialist in my city and described my symptoms. He assured me, "You don't have rabies. Go home and live your life." Of course, there was no way to verify his claim. Apparently, there's no such thing as a reliable rabies test. You can receive false negatives until you are literally in the ER being resuscitated. Luckily, rabies kills quickly, so I just had to endure ten days of agony. If I wasn't dead in ten days, I would be rabies-free. That's exactly what happened. I received my additional doses and now I am fine. I wouldn't wish this experience on anyone. It's mentally and psychologically exhausting. Even now, watching videos related to rabies makes me feel uncomfortable. It took me weeks to return to a normal sleep schedule and social life. Please, if you get bitten, seek vaccination immediately.

A few points: 1) Up to 2004 no person had survived rabies after the onset of symptoms. However, since that time 29 people have survived through new techniques such as The Milwaukee Protocol. Still, when you consider that over 55,000 people die from rabies each year, 29 survivors in 18 years still means that rabies is almost 100% fatal after the onset of symptoms. 2) Birds have been found to carry rabies antibodies, showing that they’ve been infected. However they never become symptomatic. 3) At one point near the end, you imply (with a picture) that squirrels may be rabid. While this is possible since squirrels are mammals, it would be an extremely rare event, because any squirrel that’s bitten by a rabid animal will very likely die immediately. This is why rabies is more common in larger mammals, which can be bitten but survive long enough for the virus to incubate.

Tetanus coming from rusty metal is a medical old-wives tale, you can get tetanus from anything unsanitary, it’s a bacterial infection.

[@shaggyrogers9028]

Actually, tetanus doesn't have much to do with rusty nails, the bacteria that causes it lives in a lot of places, almost everywhere. For example, if you cut yourself, and then smear dirt all over the cut, you might get tetanus. Rust is just usually an indicator that the nail itself probably has the bacteria on it, because it's been out for long and had a good chance to get infected, and nails are just... pretty good at poking you and getting the bacteria in your body, but the disease itself doesn't have much to do with rust.

@@65nidheeshkumarprabakaramo68 The extrinsic pathway for apoptosis induced by CD8 cytotoxic T cells involves FAS signaling and utilizes caspase 3 to activate apoptotic effectors, thereby inducing DNA and protein digestion within the cell and ultimately leading to blebbing from the membrane while containing the viral particles within those discrete membrane pieces. While recent literature have identified alternative routes such as necroptosis, it would appear that mechanism may be involved in the lysis of tumor cells. Furthermore, from an evolutionary approach, it would appear counterproductive for the immune system to utilize necrosis in the case of viral infection due to how the rupture of infected cells results in the explosion of infectious particles into the surrounding matrix, thereby further propagating the infection.

The Milwaukee Protocol was, at one point, theorized as our best chance to combat rabies once it entered the body in the event that it was too late for the vaccine but before advanced symptoms developed. The idea was to put the patient in a medically induced coma and being pumped with antivirals as well as other drugs such as Ketamine. The suppressed brain activity would essentially slow the spread of the virus which would provide the body with extra time to combat the viral infection. While it worked in one case which became the first known survival of rabies it also failed in over two-dozen other attempts and is only seen as a last resort.

[@WhoWantsCake0]

Just wanted to point out that while the animation at 8:40 shows a squirrel foaming at the mouth, squirrels and small rodents are almost never found to be infected with rabies. The leading hypothesis as to why is that in order to be infected the small animal has to get bit, but when the animal is that tiny they usually just die from the mauling before becoming infectious. That's why if you get bit by a squirrel, rat, mouse, rabbit, etc. doctors will usually brush it off unless you specifically saw the animal showing symptoms (foaming, erratic/aggressive behavior, averse to water)

this is the story of my heart. for more than half a year I am very sensitive to animals that transmit rabies. even when I pass by, or see a dog I break out in cold sweat, and immediately run away from it. I don't even want to step on the floor of the house, if there are guests who have dogs. Even holding money I wash my hands 😭. I also consult a doctor every time I see a dog, I ask if I catch rabies if the virus evaporates in the air. In fact, I always felt that my life would not be long, even though I had never been bitten or scratched by an animal. and every day I'm always in a panic. I don't know, because when I went to school I passed a dog. until I always buy handsanitazer and masks when leaving the house. oh god I'm tired of living in fear. every day there is something that makes me afraid of rabies. and today I met a bat when running the motorbike at high speed and the bat was right in front of me but fortunately after I checked my body no one was bitten. and I am currently haunted by what if bat saliva gets into my eyes. and it always gets past me. i hope nothing happens what i want . God bless

Whatever happens is God’s decision, so it will always be for the better. Jesus loves you, accept His peace through a prayer like this: God, I love you.

Only 29 documented people have survived rabies. 18 of them had severe damage like complete paralysis. One of the 18 died five years later, anyway. 4 had moderate damage like partial paralysis. 3 had mild side effects likes weakness, poorer coordination, or involuntary movements. Only two made a complete recovery with no noticeable symptoms. Also, only 2 of the 29 people who recovered weren't vaccinated. Most of the 29 cases' vaccination failed. Out of the two complete recovery cases, one (17 yr old from Turkey) received one dose of a rabies vaccine post-exposure (you should get 4 doses plus immunoglobulin). The other case (6 yr old from USA) received a dose of a vaccine just two days before symptoms showed up (18 days after the bite), which is definitely too late. It's said that after 3 days, it's too late to get vaccinated and this is 6 times that, so it's unclear how much the vaccine helped. Neither of these patients were treated with the Milwaukee Protocol or Recife protocol since the American kid's case happened in 1970 (Milwaukee Protocol was first used in 2003) and the other kid's case was in Turkey in 2008, only 5 years after the Milwaukee protocol's first use in a different country. That said, it's not very common to use the Milwaukee protocol. Only 36 patients were treated with it, out which 5 survived, yielding it a 14% survival rate compared to 0% of people: 29 people including those who survived using the Milwaukee protocol out of so many people: 59,000 dead every year worldwide (that's every year, not total).

So, yeah; There were countless false reports about rabid raccoons being Everywhere. From the way of things, it was easy to believe that stepping outside just for a moment, to call the family cat or dog, or do anything, really, was pretty much a guarantee of being bitten by a swarm of crazed raccoons, and then slowly and painfully turned into a rabid, hybrid, zombie raccoon person, like in a real life Stephen King book.

(also the motor proteins are borderline impossible to properly explain so that incredible drawing will help too) On a completely separate note, I find it intriguing that rabies maintains a lysogenic stage even while active, conventional knowledge is that if a virus is active it is always chewing through cells as well as creating plenty of MHCI markers so it is always impressive to find an exception to the rule. It also is puzzling to me as to how an infection that does not destroy a cell still ends up killing or at least disabling it. Perhaps the viral proteins simply oversaturate protein production making it impossible for crucial proteins to be made meaning it would simply disable the neurons rather than killing them.

If it counts for anything, diseases such as "Mad cow disease" (Bovine Spongiform Encephalopathy), or the similar condition in humans (Creutzfeldt-Jakob Disease) are FAR scarier. While they aren't common, they're 100% fatal, there is no treatment for them, there is no current diagnostic test that can be used to detect the disease before death, and usually symptoms don't appear until you're well into your 50's/60's, regardless of when you were exposed. It presents very similarly to dementia, so it can be difficult to diagnose, but unlike dementia, people suffering from CJD tend to not survive more than a year past the appearance of symptoms. Even more wild is the fact that it can be caused by a rare genetic mutation, and that mutation can be passed to your children, increasing their chances of developing CJD on their own without being infected. It is caused by a misfolded protein, called a prion, and these prions induce misfolding in normal proteins. And since it is just a protein, you cannot just "disinfect" contaminated surfaces, and it cannot be "killed", per se. Because it's not alive, it can stay on surfaces for upwards to two years, remaining infectious the entire time. CJD is the reason why most countries do not allow people to donate blood if they spent more than 3 months in the UK between 1980 and 1996. As a medical lab technologist, there is not a virus or bacteria that scare me more than prions. And not because they are common, or super infectious or anything like that, but rather because they're so insidious. Imagine rabies, except it cannot be detected until you die, it presents similarly to dementia and can be missed, it can potentially remain on surfaces for years infecting you long after the surface was contaminated, it doesn't present symptoms for 10-40 years after infection, and it's 100% fatal. At least you can be protected from rabies, and there are very successful treatments up until the final stage of infection. Id much rather take my chances with Ebola or Lissavirus. Nothing scarier than getting a call from a doctor that the CSF you just processed last week came from a patient who is now suspected of having CJD (or worse, now confirmed). You have no idea where those prions potentially have ended up, and the amount of cleaning of the lab that occurs because of them is mind boggling. @Kurzgesagt, you should totally do a video on prion diseases!!

No need to be terrified of it. Just get a vaccine.
