Superbugs, bacteria that are immune to all antibiotics, have health care professionals worried. They can cause pneumonia, urinary tract infections, and bloodstream infections. This past summer seven people died of a superbug at an NHI clinic in the Washington D.C. area, and now the antibiotic-resistant bugs have been found in hospitals in Minnesota. According to State epidemiologist Ruth Lynfield, they’re not that common in our state, but there is concern not just that superbug germs could spread, but that these bacteria could spread to other strands of bacteria. On the larger health care spectrum this is a warning sign that the pharmaceutical industry should continue to develop new antibiotics as we approach “a post-antibiotic era.”
