A rarefied term call elephantiasis , which tend to strike masses in tropical parts of the world , was long thought to come due to a parasitic contagion . But a new discipline show that the condition can have another crusade : keen crystals find in certain soils .
Inelephantiasis , a person ’s limbs become discolored and egotistical with fluid . They may tumesce to enormous size of it , resemble the limbs of anelephant . The most common cause of the condition is a mosquito - borne parasitic infection call lymphatic filariasis , in which microscopic worms invade the body ’s lymph nodes and vessels , causing the swelling .

But in 2014 and 2015 , there were reports of two vivid eruption of elephantiasis in westerly Uganda , an surface area that is not bonk to harbour these worms . [ The 10 Most mephistophelian and Disgusting Parasites ]
Indeed , when the Uganda Ministry of Health investigated the irruption , the agency identified another causa of elephantiasis : a disease call off podoconiosis . And what was thought to be an outbreak of a parasitic disease was far from it ; rather , the symptoms of podoconiosis slowly build up over decades , gradually recrudesce into elephantiasis , the survey say .
" People can be suffer from podoconiosis , a noninfectious disease , for ten before it becomes obvious that they are develop elephantiasis , " lead study generator Dr. Christine Kihembo , a elderly subject field epidemiologist at the Uganda Ministry of Health , said in a assertion . " Many of the citizenry touch in western Uganda probably had been suffering silently without help for more than 30 years . "

In September 2015 , Kihembo and her team bring down the region to seek to determine why people there were getting the disease . Their findings were published published Monday ( April 10 ) in the American Journal of Tropical Medicine and Hygiene .
In the study , the researchers looked at 52 hoi polloi who had hard , asymmetric swelling of both legs that live on for at least one calendar month , along with other relevant symptoms , such as itching or burn off in their legs , fixed toes and skin with a " mossy " coming into court , the researchers wrote in the written report .
They ran lineage tests and ruled out the usual case of this swelling , the leechlike transmission called lymphatic filariasis . In 40 of the 52 hoi polloi with symptoms , the sponger contagion was not found . And so the research worker concluded that these 40 citizenry plausibly had the other cause of the puffiness , podoconiosis .
But what causes podoconiosis ? To suffice this query , the researchers take care to the soil .
Prolonged photograph to volcanic soil was call up to stimulate podoconiosis , the study enunciate . When a person spends a circle of time walk barefoot on volcanic soil , mineral quartz penetrate the soles of his or her foot . These lechatelierite make their way into thelymphatic system , and damage it . The lymphatic system , which includes the lymph nodes , is a internet of tissues and organs that help rid the torso of waste . When the system is damaged , a clear fluid called lymph , which containswhite lineage cellphone , can build up , causing the characteristic lump of elephantiasis .
From interviews with the participants , the research worker learned that about one-half were farmers . Of these Farmer , about two - third never wore shoes while farming and two - third never washed the soil off their feet during the day , the researchers found . In line , most of the masses in the restraint group hold out place while farming . However , not wearing skid at rest home was also associated with developing the disease .
Farming whilebarefootwas strongly associated with germinate the disease , the researchers write .
Indeed , the researchers recommended that in the future , the villagers be provided with shoes to help shorten their risk of developing the disabling disease .
