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.
South Korea's Health Ministry confirmed five additional cases of Middle East Respiratory Syndrome (MERS) on Thursday, raising the total to 35, including two more health care workers who treated infected patients.
Aside from the health care workers, one of the new confirmed cases was in a person who had shared a hospital room with an infected patient and two were in people who had visited the ward at another institution where the country's first confirmed patient had been admitted, the ministry said.
The transmissions occurred before the existing patients were confirmed to be MERS positive, the ministry said. Three health care workers have previously been diagnosed as having MERS.
