Antimicrobial resistance (https://nnast.org/) occurs when bacteria, viruses, fungi, and parasites change over time and no longer respond to medicines designed to treat them. This makes infections harder to treat and increases the risk of disease spread, severe illness, and death. Misuse and overuse of antibiotics in humans, animals, and agriculture accelerate antimicrobial resistance, making it a major challenge for healthcare systems and global public health efforts.
