The Absolute SCARIEST Human Parasites!

Check out the worst human parasites that you
definitely don’t want to get! 8 – Pork Tapeworm
The pork tapeworm is one big reason to not undercook pork. The adult pork tapeworm is found in humans
and has a flat, ribbon-like body, which is white in color, and measures on average 2
to 3 meters in length! But they can become much larger, and some
worms can grow to over 8 meters long! After some unlucky person eats infected pork,
the larva found in the meat finds its way into the small intestines of its host and
attaches itself on the intestinal wall, where it grows in size with nutrients from its surroundings. The worm itself really isn’t a problem,
but it’s really the eggs it produces that are the issue. Basically, the eggs hatch into what’s called
oncospheres, and these guys migrate to places such as striated muscles, liver, and the brain,
where they settle to form cysts. If you get one of these cysts in the brain,
THIS is when major problems start. Everything from eye problems, blindness, seizures,
paralysis or even death…..well, that escalated quickly! I guess this is what happens when things start
eating your brain. This parasitic infection is THE main cause
of acquired epilepsy worldwide. The answer to everything? Thoroughly cook your food! Most parasitic infestations can be completely
prevented by eating properly cooked meats, washing vegetables, and drinking clean water. 7 – Pinworm Infection
A pinworm infection, is a human parasitic disease caused by, surprise surprise, another
worm! The entire lifecycle of a pinworm from egg
to adult takes place in the human intestinal tract of whoever is lucky enough to get these
guys in their body. WInner winner chicken dinner!! You guys know I’m being sarcastic right? The most common symptom is uh……..itching
in the anal area. I bet that can make sleeping a lot more fun. The craziest thing about these worms is that
they could virtually be anywhere because they’ve evolved to be very effective at travelling
from host to host in egg form. These pinworms are spread ONLY between people,
as other animals don’t spread the disease. The eggs come out first around the anus and
can survive for up to three weeks under extreme conditions. I meant that as in the eggs can still survive
on say, a kitchen counter. You can easily become infected if you touch
a contaminated surface and then inadvertently touch your eyes or mouth. Eggs are frequently swallowed following contamination
of the hands, food, or basically anything that the eggs can come in contact with. The people most at risk are those who live
in dormitories, in health care institutions, or worse yet, prisons. Another reason not to go to prison guys. The surface of the eggs is sticky, which allows
them to stick to whatever surface they can grab onto. Pretty much anything and everything you can
imagine. When these little eggs get into the dust on
the floor or on a bookshelf, they can become airborne and be widely dispersed! Another instance would be when someone shakes
out sheets or dusts furniture around someone who’s infected. This means you can get infected by breathing
infected air, touching infected surfaces, or sleeping in an infected bed even if the
originally infected person was there 3 weeks ago! It’s the most common worm infection in the
developed world, and kids in school are the most common sufferers. So if you know or see someone that’s constantly
scratching their a*s……stay away…..stay far away! 6 – Eyelash mites
Most people think that mites are usually an infestation that only affects pets, such as
cats or dogs. Welllll, these people are gonna have to think
again. These tiny, eight-legged creatures chill in
our brows and lashes, feasting on skin cells and oils that we produce. These eyelash mites, whose scientific name
is “demodex”, spend most of their time buried in hair follicles and are most active
while people sleep, because they hate light. Around 65 species of Demodex are known, but
only two species live on humans. They thrive on the natural oils produced by
the body, but both species are primarily found on the face, specifically near the nose, eyelashes,
and eyebrows, but they also can thrive elsewhere on the body. The good news is that these mites usually
don’t cause any symptoms, although occasionally some skin diseases can be caused by the mites. If you catch them under a microscope, you’ll
see them swimming around skin cells in their colonies. Mite infestation is incredibly common, in
fact, a recent study showed that mites were present in 100% of the people they tested
over the age of 18. Don’t think about it now, but this means
you and I pretty much have these guys all over our eyes. Eyelash mites are transmitted through direct
facial contact. Basically, whenever you get close to someone
that’s infected, you’re getting these mites. But then again, apparently the question is
more who DOESN’T already have these guys on their bodies?! A typical eyelash mite has a two- to three-week
cycle and will eventually die, but all their kids are just gonna continue the process. What’s the only way out of it? Steam your bed constantly and wash everything
in hot water as often as possible. 5 – Lymphatic Filariasis
Ever seen pictures of people with inflamed limbs? A lot of the time, it’s caused by parasitic
filarial worms. Having lymphatic filariasis can cause elephantiasis,
which happens when these parasitic worms lodge in the lymphatic system and cause blockages
to the flow of fluids. These worms cause swelling mainly in the lower
half of the body. So how does someone get infected? These worms are spread by the bite of an infected
mosquito. In fact, lymphatic filariasis was the first
mosquito-borne disease to be discovered. The disease is transmitted by different types
of mosquitoes, and although it mainly affects the lower limbs, different filarial worms
tend to affect different parts of the body. Adult worms live in the lymphatic system and
disrupt its function. The infestation can be controlled and even
cured if it’s detected in the early stages, but after years of affecting the lymphatic
systems and becoming a chronic inflammation, the only solution after that is surgical. About 40 million people worldwide were disfigured
or incapacitated by the disease in 2015, and elephantiasis by lymphatic filariasis is one
of the most common causes of disability in the world. 4 – Trichinella spiralis
Trichinella spiralis is a roundworm that’s commonly found in all sorts of animals, but
the most common way for people to get it is to eat undercooked infected pork. This is one of the most widespread parasites
in the world, and catching these worms is incredibly easy. The first symptoms appear between 12 hours
and two days after eating infected meat. These worms live in the small intestine of
its host. The migration of adult worms in the intestinal
walls can cause traumatic damage, and the waste products these worms excrete can provoke
a severe reach reaction, such as nausea, vomiting, sweating, and diarrhea. Five to seven days after the appearance of
these symptoms, severe swelling in the face and fever may occur. Ten days following ingestion, intense muscular
pain, difficulty breathing, weakening of the pulse and blood pressure, heart damage, and
various nervous disorders may occur, eventually leading to death because of heart failure,
respiratory complications, or kidney malfunction! This is all because of larval migration. Kinda a big deal for accidentally eating some
undercooked meat don’t you think? The answer to all this? Again, just properly cook any meat that you
eat! When properly cooked, trichinella worms die. 3 – Cutaneous larva migrans
The next time you’re going off on a nice tropical vacation, be on the lookout for cutaneous
larva migrans, or CLM, as it’s quite common. If you experience intense itching and skin
eruption after visiting a sandy beach, you might have come in contact with larva of one
of the various parasites of the hookworm family. This is one of the most common types of cutaneous
conditions in the world. This parasite lives in the intestines of dogs,
cats, and other wild animals, and its larvae can live in the sand and dirt for a long time
after animals have pooped in the ground. This is actually the reason why most beaches
limit the entry of dogs and other animals. After being laid in the ground, hookworm eggs
develop over a period of 1–2 weeks into the infectious larval form that can burrow
through any intact skin that comes into contact with sand or soil that’s been contaminated
with infected feces. Because they’re able to infect deeper tissues
of other animals, such as the lungs and the intestines, humans aren’t these parasites’
ideal hosts. The larvae are only able to penetrate the
epidermis of the skin. The worms can move an inch or more everyday
creating what’s known as a creeping eruption! This can cause intense itching, but at least
it heals by itself over the next months. However, the symptoms and the intense itching
usually causes the people infected to seek medical treatment before this has time to
happen. I guess the best way to prevent this is to
just stay away from any visible logs at the beach and then you’re on your own after
that! 2 – Loa loa worm
There are a lot of different parasites that come in all kinds of shapes and sizes. The scariest of them all might be the Loa
Loa worm. Like a lot of parasites, it’s small and
it’s worm-like. Well, actually, it IS another worm. The scariest thing about it is where it could
live on humans. When a person is infected, the Loa Loa worm
can live and thrive in the eye! How exactly does someone get it? If an infected mango fly or a deer fly bites
someone, the Loa Loa parasite gets into someone’s skin, where it’ll penetrate skin tissue
and migrate, and a lot of times it’ll get to someone’s eyes. Loa loa doesn’t normally affect a person’s
vision, but it can be painful when it’s moving around the eyeball or across the bridge
of the nose. Typically these worms are found in rainforest-like
environments in west and central Africa. In the human host, the worm grows slowly and
the person rarely has any symptoms. Loa loa larvae migrate to the subcutaneous
tissue where they mature to adult worms in approximately one year, but it can sometimes
take up to four years! Adult worms migrate in the subcutaneous tissues
at a speed of less than 1 cm/min. Adult worms can live up to 17 years in the
human host! The worm will temporarily live anywhere on
the body beneath the skin. The usual symptoms are painless, but itching
and swelling can occur in any infected body part. In cooler temperatures is when the worm has
a frequency to migrate to the surface of the eye, causing itching, pain and tenderness. I’d think the worst part has to be feeling
something moving INSIDE your eye. Uggggghhhh! This small parasite has been known to have
affected Egyptian Pharaohs more than 4 thousand years ago. Hmmmm, I guess they found some of these mummified
worms out there? 1 – Leishmaniasis
If you’ve ever travelled to the jungle, you might have heard about leishmaniasis. This parasitic infestation is transmitted
by the bite of an infected sandfly and affects the nose, mouth and that general region. This parasite usually targets the most superficial
layers of the skin, and the Brazilian version travels through the skin until it reaches
the nose, mouth and pharynx region of whoever it’s found. This infection might even lead to the complete
destruction of the nose and other mucosa. Not exactly a nice little souvenir! Leishmaniasis infestations develop in the
form of painful ulcers in the skin and it can become infected if the patient scratches
their skin and then doesn’t take care of the wound. When it reaches the nose, the patient might
feel nasal symptoms such as stuffiness or bleeding. It can go unnoticed for up to twenty YEARS
and, if left untreated, these ulcers can evolve and cause serious oral and nasal lesions. This damages the mucus membranes and ultimately
destroys much of the affected areas, such as perforation of the nasal septum. Ugh. As It turns out, there are no vaccines or
drugs to prevent infection, and the only way is to avoid getting bitten by an infected
fly. Yeah, that’s gonna be a bit tricky. Here’s what’s next!

  1. I'm so glad that most of these aren't fatal.

    Eyelash mites are my homies. Feel free to chill at my pad and drink all the free grease you want.

    Botfly Larvae and Hookworm aren't that bad if you get treatment quick.

    Always cook your food til it's 70 degrees (Celsius) or more. You can buy a thermal probe to check the temperature of meat online. If not just be sure to preheat your oven and follow the cooking instructions on your food. Even if you slightly burn your meal it's much better than getting parasites.

    If you're going near the equator or the southern hemisphere, be sure to research what diseases and parasites are there and how to avoid getting infected.

  2. theres this mate whp thinks he can be on every comment

    technically. if i delete this comment, he is unable to be on this comment and therefore is not on every comment

  3. I have pinworm
    they are so fucking annoying they wiggle like crazy. I feel to insert a nuke i inside. it feels great when I fart

  4. if i had Cutaneous larva migrans i would just slice my skin and take out the worm (i have no problems cutting my skin..thats why im wierd)

  5. I had pin worm when I was like 12 or 13 and I literally couldn't sleep because I could feel them moving and crawling around
