C. Diff Nearly Always Linked to Health Care

About 92% of U.S. cases of a dangerous intestinal infection are related somehow to health care, a government study finds. About 3 out of 4 people began to show symptoms outside of hospitals. But most had recently been in a nursing home, hospital or doctor’s office. The study focused on Clostridium difficile (C. diff). The infection often occurs in people who recently took antibiotics for another reason. These drugs also kill “good” bacteria, allowing C. diff to grow and release toxins. Researchers from the Centers for Disease Control and Prevention (CDC) did the study. They used laboratory data on stool tests in 8 regions. Only 1 out of 4 patients was in a hospital when symptoms began. Another 1 out of 4 had been in a nursing home. But about 2 out of 3 nursing home cases had been in the hospital recently. Some hospital cases also had been in nursing homes recently.
