Antimicrobial resistance (AMR) is one of the most consequential but under-recognized threats to global health. When bacteria, viruses, fungi or parasites evolve to withstand the drugs designed to kill them, routine infections become harder—or impossible—to treat. This undermines surgeries, chemotherapy, childbirth safety and everyday care where antibiotics are relied upon.
Why AMR matters
Resistant infections increase illness duration, healthcare costs and mortality risk. They strain hospital capacity and complicate management of chronic conditions.
AMR also threatens food security when resistant pathogens affect livestock and crops. Because microbes spread across borders, no country is safe until AMR is controlled everywhere.
Main drivers of resistance
– Overuse and misuse of antimicrobials in humans: prescriptions for viral illnesses, incomplete courses and self-medication accelerate resistance.
– Agricultural use: antibiotics used for growth promotion or routine disease prevention in animals select for resistant strains that can transfer to people through food, environment or direct contact.
– Poor infection prevention: overcrowding, inadequate sanitation and under-resourced healthcare settings facilitate transmission.
– Weak surveillance and diagnostics: without timely detection, resistant infections circulate unchecked and clinicians resort to broad-spectrum drugs.
– Limited new drug development: economic and scientific challenges mean fewer novel antimicrobials reach the market.
A One Health response
AMR requires a One Health approach that links human, animal and environmental health.
Coordinated policy and practice across these sectors improves outcomes and keeps interventions aligned.
Priority actions that reduce risk
– Strengthen antibiotic stewardship: hospitals and clinics should implement stewardship programs that guide appropriate prescribing, use rapid diagnostics, and review antibiotic use regularly.
– Improve surveillance and data sharing: expanded, standardized surveillance in community and clinical settings helps identify resistance trends and informs targeted responses.
– Scale up infection prevention and control (IPC): hand hygiene, clean water, sanitation, vaccination and safe healthcare practices cut transmission at the source.
– Reduce agricultural misuse: phased limits on non-therapeutic antibiotic use in livestock, combined with better animal husbandry, reduce selection pressure.
– Incentivize research and development: push-pull mechanisms, public–private partnerships and market-shaping policies can revive antibiotic pipelines and promote alternative therapies like phage therapy and immunomodulators.
– Encourage vaccination: vaccines prevent infections that might otherwise require antibiotics, lowering overall antibiotic use.
– Environmental safeguards: monitoring pharmaceutical waste and improving wastewater treatment reduces environmental reservoirs of resistant genes.
What individuals can do
– Use antibiotics only when prescribed and complete the full course if prescribed.
– Avoid pressuring clinicians for antibiotics for viral illnesses; ask about symptomatic care and expected timelines.
– Practice good hygiene: handwashing, food safety, and keeping vaccinations up to date protect against infections.
– Support responsible food choices: seek meat raised without routine antibiotic use when possible and advocate for transparent supply chains.
– Stay informed and support policies that strengthen stewardship, surveillance and sanitation investments.
Global coordination and local action together create the strongest defense. By reducing unnecessary antibiotic use, improving infection control, and revitalizing drug development, health systems can preserve lifesaving medicines for current and future generations. Every sector—from clinicians and farmers to policymakers and individuals—has a role in slowing resistance and protecting global health.
