The Bugs That Lay Eggs All Over Your Body

The Bugs That Lay Eggs All Over Your Body

In 2018, a cockroach crawled
inside a sleeping man’s ear and laid an egg sac. Luckily, roaches don’t go
out of their way to do this, so it doesn’t happen very often. But there are a bunch
of other unsavory bugs that will lay eggs all
over your body on purpose. First up, the human botfly. These insects, which are native to Central and South America, glue
their eggs to mosquitoes and other blood-sucking insects. When the mosquito bites
you, the eggs hatch. Then the larvae wriggle into your skin, creating a painful pimple that leaks pus. Or, as the baby botflies call it, lunch. After five to 10 weeks, they escape. Not long after that, they reach adulthood, ready to mate, and start
the cycle all over. Another tropical parasite
is Tunga penetrans, more commonly known as the sand flea. Females burrow into
the bottom of your foot and slurp your blood. They start off smaller
than a grain of sand but grow to 2,000 times
their size within a week as they swell with your
blood and up to 200 eggs. Those eggs fall to the ground and hatch, waiting for the next bare foot to pass by. But some egg-laying parasites
go more than just skin deep. Tapeworms, for example,
invade your intestines. Adults can grow to be
longer than a bowling lane and block up your digestive system. But it gets worse, because they lay tens
of thousands of eggs, which can hatch and migrate, spreading throughout your lungs, muscles, and even your brain. If that sounds gruesome,
just wait till you hear about the Loa loa worm. It can be passed from human to human by hitching a ride inside of deer flies. When the flies bite you, the
larvae enter through the wound. After five months growing
beneath your skin, they reach adulthood and start to release thousands of embryos a day. Sometimes you can even see the worms moving under your skin
or across your eyeball. But, hey, not every egg-laying
invader is sinister. Face mites, for example,
are pretty innocuous. They live on pretty much everyone’s face, and most people just never notice. After all, they feed on
facial oil, not flesh. When it comes time to breed, females just lay one egg
inside of your pores. Even better, researchers can
now study your face mites to track how your ancestors
migrated across the planet, because we usually pass
them from parent to child, so the mites stay in the family. But face mites aren’t the
only helpful bug around. Green bottle flies might
be useful in medicine. They lay their eggs inside of open wounds, and then the maggots hatch
and devour the damaged flesh. That sounds brutal, but one day we might be able to harness this process to treat diabetic foot ulcers and other slow-healing wounds. Because when the maggots go to town, they actually clean the area and remove a lot of the dead tissue. They even secrete proteins
that reduce inflammation. So maybe botflies, fleas, and tapeworms could learn a thing or two and at least make themselves useful if they’re going to move right in.

  1. Half of my brain before clicking the vid. "Come on dude, that's new info."
    After watching my brain's ranting " you'll regret why u click this!"

  2. The tapeworm animation is incorrect. Only one tapeworm survives in the small intestine and the rest of them are killed because of auto-immunity. Their eggs are all passed out with the faeces. If those eggs somehow get into the human body, they hatch and subsequently, the Cysticercus larva is developed that may reach the brain.

  3. In around 400 Billion years us and another galaxy will crash and everything will be distroyed they better not take there sweet as time

  4. Ever since learning the beauty of bees in this world and meeting cute baby snakes, this doesn’t creep me out/ gross me out heh 😅

  5. True story: I never knew cockroaches could crawl into human ears until it happened to my ex's sister. She went to hospital complaining she felt movement and pain inside her ear. When they checked, they found a small roach trying to burrow into her ear canal. To get it out, they had to quickly kill the roach without scaring it (or it'd burrow harder and damage her ear drum). My ex didn't tell me what they used to kill it, but the roach died and they used thin tweezers to pull it out. After he told me about her experience, I wore ear plugs to sleep for 2 weeks 😅
    I felt bad for his sister, her siblings would tease her about it.

  6. Loa Loa worm:
    Loa loa is commonly found in Africa. People at the highest risk for acquiring loiasis are those who live in the rainforests of West or Central Africa. Furthermore, the probability of getting bitten by a deer or mango fly increases during the day and during rainy seasons. The flies are also attracted to smoke from wood fires. These flies do not commonly enter houses, but they are attracted to the houses that are well lit, so will congregate outside.

    Travelers can be infected in less than 30 days after arriving in an affected area, although they are more likely to be infected whilst being bitten by multiple deerflies over the course of many months. Men are more susceptible than women due to their increased exposure to the vectors during activities such as farming, hunting, and fishing.

    Reports of microfilaremia have been made in Angola, Benin, Cameroon, Central African Republic, Congo, the Democratic Republic of Congo, Equatorial Guinea, Gabon, Nigeria, and Sudan, and possibly rare cases in Chad, Ghana, Guinea, Liberia, Uganda, and Zambia. Of the 10 countries that have high rates of infection, about 40% of the people who live in the area have reported being infected with the worm in the past. The population in high-risk areas is about 14.4 million; in addition, 15.2 million people live in areas where around 20–40% of people admitted to having the worm in the past.

    A study performed to review reported cases of L. loa in nonendemic countries in the past 25 years reviewed 102 cases of imported loiasis, 61 of them from Europe and 31 from the USA. Three-quarters of the infestations were acquired in three countries considered endemic: Cameroon, Nigeria, and Gabon. In the subjects viewed, peripheral blood microfilariae were detected 61.4% of the time, eye worm migration 53.5% of the time, and Calabar swellings 41.6% of the time. A trend appeared in the symptoms of the patients where Calabar swellings and eosinophilia were more common among travelers. African immigrants tended to have microfilaremia. Eye worm migration was observed in a similar proportion between the two groups. Only 35 of the patients underwent clinical follow-up. The researchers concluded that L. loa would end up migrating to Europe and the United States, due to increased travel to already endemic regions.

    Prevention:
    Currently, no control programs or vaccines for loiasis are available. However, diethylcarbamazine treatment is suggested to reduce risk of infection. Avoiding areas where the vectors, deer and mango flies, are found also reduces risk. This includes swamps, bogs, and shaded areas near rivers or near wood fires. Fly bites can be reduced by using insect repellents such as DEET and wearing long sleeves and pants during the daytime. Permethrin treatment on clothes is an additional repellent that could be used. Also, using malaria nets can reduce the number of fly bites acquired.

    Treatment:
    In the western part of Africa, an increase in prevalence has been associated with the distribution of ivermectin, which is used to prevent the infection of onchocerciasis, which is also very prevalent in the same region. Patients with L. loa who are treated with ivermectin have extreme adverse effects, including death. 

    Ivermectin has become the most common antiparasitic agent used worldwide, but can lead to residual microfilarial load when given in the management of loiasis. Treatment with ivermectin has shown to produce severe adverse neurological consequences in some cases. These treatment complications can be increased in individuals co-infected with onchocerciasis. Some of these patients experienced cases of coma and resultant encephalopathy, parkinsonism, and death. After about 12 hours, the first signs start to appear and include fatigue, pain in joints, mutism, and incontinence. Severe disorders of the consciousness start to develop after about a day.

    Although Ivermectin is a common treatment for loiasis, the Center for Disease Control (CDC) recommends treatment with diethylcarbamazine (DEC). Symptoms may be resolved with as little as 1-2 courses of DEC. DEC is chosen over Ivermectin because evidence supports its ability to kill both the adult worms and the microfilariae, which are the main cause of the severe neurological problems mentioned above. In some cases, albendazole may also be an effective treatment used to reduce the microfilariae prior to treatment with DEC. The body's response to albendazole is slow, so the patient being treated must be monitored closely and frequently to ensure it is effective.

  7. Oh my god i always habe pimples like that described in the video and i have no idea that a bug will crawl into my body 😭😭😭

  8. I work at a veterinary hospital, and you would not believe how large botfly larvae can become if they are trapped under a dog’s skin. It’s absolutely disgusting removing them.

  9. Why the hell I watched this video. I shouldn't have clicked on it. I will not be able to sleep tonight. Feeling so disgusting 🥺😬😬😟😟😟😟😰😨😨😰😰😥😥😥😱😱😱😵😵😵😵😩😩😩😩

  10. Stopped after lay sack of eggs that happened to my neighbor in Haiti 😭 i don't need to know anything else NoT watching it🚶🏾‍♀️🚶🏾‍♀️🚶🏾‍♀️🚶🏾‍♀️

  11. This why i take two shower by day and i eat garlic and olive oil at each meal.
    I know it's pure placebo, but i can't handle the parasite bug thing.

  12. I like green bottle flies and face mites cause the green bottle flies clean the area and remove the damaged tissue
