Here are the 10 most invasive parasites inthe world. Despite their size, these tiny terrorizers will leave you digging into yourown skin. Number 10: Blood FlukesScientifically known as schistosoma, blood flukes are one of the most common parasitesin the world, affecting hundreds of millions of people worldwide. They're a type of flatwormparasite that uses snails as an intermediate host by latching onto them then attachingthemselves onto human skin hatching eggs inside the human's bladder or intestine. Once inside your body, blood flukes can livea very long time. The initial symptoms of
itching rashes begin appearing in just afew days. After a couple months, diarrhea, coughing, headaches, fever will likely occur.Several years of leaving it untreated will then lead to the eggs spreading infectingorgans such as the lungs, liver, bladder. They may even affect the spinal cord and brain,thus causing paralysis seizures. This parasite is found primarily in Africa,the Middle East, South America, parts of South Asia. Children are at especially highrisk as they can develop learning disabilities suffer from malnutrition. As such, the WorldHealth Organization considers blood flukes to be among the most socioeconomically damagingparasites in the world.
Number 9: The Horsehair WormAlso known as â€œgordian wormsâ€� or â€œnematomorpha,â€� the horsehair worm is a parasitic worm foundin watery areas such as pools, creeks, puddles. Scientists believe this parasite is comprisedof anywhere between 350 to 2,000 different subspecies. While horsehair worms do not pose any directthreat to humans, they do pose an interestingly unique specific danger towards crickets.They hatch as larvae at the bottom of a creek, stream, or puddle, then wait to be eaten bya cricket. Once consumed, the horsehair worm will navigate its way into the cricket's bodycavity, where it absorbs nutrients from the
cricket. As soon as this parasite breaks free,it coaxes the cricket into drowning itself so the horsehair worm can fully emerge. Afterleaving the dead cricket, it then finds a mate, who helps it reproduce by laying eggs.The male worm dies the deadly cycle continues. Number 8: RoundwormsRoundworms are parasites responsible for causing a disease in humans known as filariasis. Carriedby flies mosquitos, they infect one's bloodstream with the potential to reach the lymphaticsystem, causing the body parts (such as your limbs genitals) to swell up well beyondtheir normal size. The skin will also become thick painful as a result of infection.
Roundworminduced filariasis affects closeto 1 billion people in 80 countries throughout the world. Fortunately, this condition istreatable through the use of oral drugs such as Diethylcarbamazine, which kills off theinfection prevents further transmission to other people. Number 7: The Tsetse FlyFound in Africa, the tsetse fly is one of the main causes of trypanosomiasis, or Africansleeping sickness. This parasitic disease affects roughly 10 million people is mostcommon in more rural areas. Symptoms include headaches, fever, joint pain,poor coordination, confusion, muscle weakness,
paralysis of the limbs, trouble sleeping.It can eventually prove fatal if treatment is not sought, causing death due to eventualorgan failure. While the disease has been present in Africafor thousands of years, the death rate has decreased in recent years due to advancesin modern medicine. In 1990, for example, about 34,000 people died from African sleepingsickness, which is close to four times higher than its current death rate of 9,000 peopleper year. Number 6: The Emerald Jewel WaspAlso known as the â€œemerald cockroach,â€� the emerald jewel is known for paralyzingcockroaches in order to use them for their
