Receiving medical care for any reason may increase the risk for hepatitis C and B, according to a study in the journal Hepatology. Older adults with hepatitis were more likely than healthy patients to have had surgery, blood transfusion, hemodialysis and health care-related injections, the study said. Patients with the disease also were more likely to have been treated at an emergency room or stayed at a hospital overnight. "Our case-control study demonstrated that health care exposures may represent an important source of HBV and HCV infection among older adults and suggests that health care transmission is not limited to recognized outbreaks," according to researchers.
