A leechlike disease affecting mammals , medieval serfs view as what we now know as dracunculiasis as an intrusion of bantam dragons — dragons that finally burrowed out of the pelt . Multiple ancient text refer to the disease , with the manner for process dracunculiasis go forward to be a uncomplicated one . But how does one become infected with these “ flyspeck dragons ” , what is the protrusion mental process like , and how has one group nearly eradicated the disease in a little over 25 years ?
admonition : The following contains an ikon of a guinea fowl dirt ball origin as well as a Carter Center video detailing the process .
How is this invasion of “ little dragons ” spread ?
The oldest reference to what we now call dracunculiasis is a 1550 B.C.E Egyptian text , theEberstext , which document the disease and a build of intervention . The scary - as - hell “ small Draco ” language comes from a Latin origin of the intelligence dracunculiasis .
Modern causa of dracunculiasis are predict by a childlike name , ginzo louse disease . This modification in names is due to an early modern watching of the disease in humans living along the Guinea Coast of West Africa .
Copepods , a bantam crustacean present in stagnant water , is the delivery method acting of choice for Dracunculus medinensis larva . One can observe copepods on the airfoil of water — these arthropod show up as trivial white-hot specks dancing on the surface . Due to a lack of drinking water in touch on areas , this foul water often has to be used , let a embarrassment of these Dracunculus medinensis - carry copepod to build up the body .
When swallowed , the copepods are break away asunder in the digestive tract , releasing the Dracunculus medinensis larvae into the intestine and beginning a year of pain .
Moving from the intestines throughout the soundbox , the grown worm often settles in subcutaneous tissue paper . Within humans , the white worm grows to up to a meter in duration and to a thickness of up to 2 millimeters over the course of a twelvemonth — about the same width as angel hair pasta .
At the end of a class , the louse set out to exit the human horde . The worm typically leaves through the leg or foot , but cases of exit through the testes or the tissue around the heart are on record .
New larvae are enclose into the water supply when the afflict attempt to benumb the pain in the ass brought about by a guinea worm by submerging the exit wound in water . This lead off the round again , inaugurate more Dracunculus medinensis larvae into the water provision , which latch onto copepod .
Due to the tenacious brooding menses , a human host will go the good part of a twelvemonth without symptom . When symptom do arise , they are often drain , taking the person out of work and category life for the excruciatingly afflictive 2 - 3 calendar month peroid as the dirt ball makes its exit or is delicately teased out . This downtime is particularly prejudicial to children , as the young are often pick out out of school to work and leave for their phratry if a parent or provider is infect .
descent must be carried out slowly . The patient ’s extruded dirt ball is often wrapped around a little stick , with fossil oil used to help physically aid remotion , a procedure that can only squeeze out centimeters of a worm at a time . If emphatic removal of the worm is attempted , its 1 milimeter body can snap , leaving a long segment inwardly of the body to putrefy , damaging the tissue around it , or calcify .
Eradicating this gruesome disease
In the mid-1980s , former United States President Jimmy Carter , through the Carter Center , push for obliteration of dracunculiasis through education of at - risk of exposure population .
By post security force around inland water supply , doling out information as to how to filter copepod in drinking urine , and encouraging at - house treatment of exiting insect using a musical composition of equipment as simple as a plastic bucket fill up with water , the number of afflicted has decrease from3.5 million casesin the mid-1980s to less than afew thousand casesa year worldwide .

The bucket of water is used to provide the same relief to the patient as that sought by dip the exposed field in nearby body of crapulence water . The water is then spread along the terra firma out from a body of weewee , leading to the dying of larvae as the answer dry .
Thanks to these practices , the Carter Center , which currently receivesfinancial aidfor the effort from the Bill and Melinda Gates Foundation , is unaired to eradicate this gruesome disease worldwide .
