What Is Antimicrobial Resistance and Why Is It a Threat?
Antimicrobial resistance (AMR) occurs when microorganisms such as bacteria, viruses, fungi, and parasites evolve to resist the effects of drugs that once killed them. This makes infections harder to treat and increases the risk of disease spread, severe illness, and death. AMR is a growing threat worldwide, exacerbated by the overuse and misuse of antibiotics in humans and animals.
