An Italian study—prompted by a local outbreak—found that 82% of people who were clinically affected also had pre-existing symptoms of irritable bowel syndrome. In these patients the antibiotic given to eliminate the bug didn't modify the symptoms, but in those without irritable bowel syndrome the treatment was clearly …
