As if they didn`t have enough to worry about.
A North Korean defector shot five times while running across the border to South Korea has been found riddled with parasites, one of which has never been seen in the country.
North Korean defectors often come over to South Korea with parasites, in one case with more than 30 types of ringworm.
South Korean surgeons operating on a North Korean defector who ran across the Demilitarised Zone between the two countries under a hail of gunfire on Monday have found a parasite in the man`s stomach unlike any other they had seen.
The defector, who was shot five times, remained in critical condition after hours in two rounds of surgery, said an article in the Korea Biomedical Review published Wednesday.
"We are struggling with treatment as we found a large number of parasites in the soldier`s stomach, invading and eating into the wounded areas," Lee Guk-jong, the physician who treated him, told the Review.
"We have also discovered a parasite never seen in Koreans before," Lee said. "It is making the situation worse and causing tremendous complications."
It`s unclear whether the parasite has been seen in other parts of the world.
A professor at a medical school told the Review that North Korean defectors would often come to South Korea riddled with parasites, with one patient having more than 30 types of roundworms in her body.
The problem is common among defectors, the professor said, but may not be reflective of the North Korean population.
But the case of this defector stands above the others - his small intestine is ruptured, contaminated with faecal matter, and infected with parasites, Lee told the Review.
"He has everything that he could have," Lee said.
"It is very likely that the prognosis will be worse than other general trauma patients as he has been in a state of shock induced by heavy bleeding and we expect to deal with many complications."
