Antibiotics, antivirals, and other antimicrobials have saved millions of lives worldwide, but these drugs are losing their effectiveness because of antimicrobial resistance. Antimicrobial resistance refers to microbes' natural ability to evolve genetically to counter the drugs. Some of this is inevitable, but over-prescription and improper use of antimicrobials plays a big role. Up to half of antibiotic use is unnecessary or inappropriate.
Drug-resistant infections can strike anyone—young or old, healthy or sick, as these real life patient stories show. Treating resistant infections costs the U.S. health care system an estimated $21 billion to $34 billion annually. IDSA is working on many fronts to counter these "bad bugs" and save lives.
Faces of Antimicrobial Resistance: The Human Cost of Antimicrobial Resistance
Many patients and their families have suffered the debilitating effects of antibiotic-resistant infections, and more and more patients are losing their lives due to these infections. These compelling and heart-wrenching stories engender a strong sense of urgency to address drug-resistant infections and the lack of new antibiotic development.

Facts about Antibiotic Resistance
The discovery of antibiotics in the 1930s fundamentally transformed the way physicians care for patients, shifting their approach from a focus on diagnoses without means to intervene into a treatment-focused approach that saves lives. Now, nearly 70 years later, we’ve reached a critical point in treating infectious diseases: new drugs are not being developed at anywhere near the pace necessary to keep ahead of the natural ability of bacteria to evolve and defend themselves against antibiotics. The result is that some of our most powerful drugs are becoming useless.
