Antimicrobial Resistance

Facebook Twitter LinkedIn Email

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.
