Crohn's disease is a type of inflammatory bowel disease (IBD) that may affect any part of the gastrointestinal tract. Signs and symptoms often include abdominal pain, diarrhea, fever, and weight loss, and possible bowel obstruction. Other complications may occur outside the gastrointestinal tract and include anemia, skin rashes, arthritis, and tiredness. Crohn's disease is caused by a combination of environmental, immune and bacterial factors in genetically susceptible individuals. It results in a chronic inflammatory disorder, in which the body's immune system attacks the gastrointestinal tract possibly directed at microbial antigens.
Quarantine Area: Korean Patients Tested By Mers Lockdown
Hwang Jeong-rye went to hospital in Seoul on June 9 for a back problem and has been stuck there ever since - locked in along with 78 others as South Korea scrambles to control an outbreak of the deadly Middle East Respiratory Syndrome (MERS).
"It is a prison without bars ... It hurts me because she wants to see my face even at a distance," said Jeong Yeon-seok, fighting back tears after catching the eye of his 72-year-old mother on the sixth floor of the Mediheal Hospital.
Thousands of Koreans have been put under quarantine, including those inside two hospitals that are under a two-week lockdown - meaning no one can enter or leave.
