FDA: Antimicrobial Resistance

IDSA (The Infectious Diseases Society of America): Antimicrobial Resistance


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.

Facts about Antibiotic Resistance

The incidence of antibiotic-resistance has been rapidly increasing. At the same time, fewer new antibiotics are being developed.

Patient Stories

Many patients and their families have suffered the debilitating effects of drug-resistant infections.IDSA believes it is important to tell their stories to spur the development of new treatments and to strengthen efforts to control drug resistance. If you would like to share your story, please contact John Heys at jheys@idsociety.org.

Patient Education Guides on MRSA and other HAIs

IDSA partners with the Society for HealthCare Epidemiology of America (SHEA) and others to offer free guides to educate the public about preventing seven common health care-associated infections (HAIs). Many HAIs, such as methicillin-resistant Staphylococcus aureus (MRSA), are drug-resistant.
