Landmark CDC Report Details Threat of ‘Postantibiotic Era’

The Centers for Disease Control and Prevention (CDC) released its “landmark” report today on the rising and lethal threat of antibiotic resistance, titled Antibiotic Resistance Threats in the United States, 2013.

The report describes a complex problem and the steps that must be taken to prevent catastrophic consequences.

In it, experts describe “what happens when the microbes can outsmart our best antibiotics,” explained CDC Director Tom Frieden, MD, MPH, at a press conference. He elaborated by describing his hope that the report will prioritize pathogens and propel action to curb antibiotic resistance.
