The problem
Antimicrobial resistance (AMR) occurs when bacteria evolve to survive the medicines designed to kill them. Resistant infections are harder and costlier to treat and cause substantial global mortality.
What drives it
Overuse and misuse of antibiotics in people and animals accelerates resistance. Taking antibiotics for viral illnesses, skipping doses, or using leftover medicines all contribute.
What helps
Use antibiotics only when prescribed, complete courses as directed, never share medicines, and prevent infections through vaccination and hygiene. Health systems combat AMR through stewardship programmes and surveillance.
