Almost 100 hospitals reported suspicious data on dangerous infections to Centers for Medicare & Medicaid Services officials, but the agency did not follow up or examine any of the cases in depth, according to a report by the Health and Human Services inspector general's office.

Most hospitals report how many infections strike patients during treatment, meaning the infections are likely contracted inside the facility. Each year, Medicare is supposed to review up to 200 cases in which hospitals report suspicious infection-tracking results.

Friends and classmates of an Oviedo woman with bacterial meningitis have been notified they are at risk of the highly contagious disease that causes inflammation of membranes around the brain and spinal cord , the Orlando Sentinel reports.

The CDC is sounding alarm bells over the rise of a drug-resistant “superbug” in hospitals across the country; only six states require hospitals to report the infections, and Florida isn’t one of them, McClatchy Newspapers reports. 

Federal officials warned Tuesday that an especially dangerous group of superbugs has become a significant health problem in hospitals throughout the United States.

These germs, known as carbapenem-resistant Enterobacteriaceae, or CRE, have become much more common in the last decade, according to the Centers for Disease Control and Prevention. And the risk they pose to health is becoming evident.
