Human health
Resistant infections can make common treatment more difficult and increase the burden on patients and health systems.
Animal health
Antimicrobial use and resistant organisms connect veterinary care, livestock and food systems.
Environment
Water, wastewater, soil and waste can carry antimicrobials and resistant organisms between settings.
How resistance can spread
Between people and care settings
Contact, travel, healthcare and shared environments can connect transmission pathways.
Across food, water and ecosystems
One Health surveillance helps reveal links that a single sector cannot see alone.
Through antimicrobial pressure
Inappropriate or excessive use can select for resistant organisms.
Prevention and surveillance
- Use antimicrobials only when needed and as directed.
- Prevent infection through hygiene, vaccination and safer care.
- Collect consistent laboratory and epidemiological data.
- Share signals quickly so teams can investigate and act.

Annual US cost (CDC)
Why misuse happens
Patients
Taking medication without prescription, using antibiotics for non-bacterial conditions such as cold and influenza, and not completing the treatment course.
Healthcare practitioners
Random dispensing of antibiotics by physicians and pharmacists increases susceptibility to resistance.
Health facilities
Absence of strategic stewardship plans and infection-control programmes worsens the condition.
Agriculture and livestock
Antimicrobial use in animals and food production drives resistance across sectors.
Regulation
Lax pharmacy legislation and weak enforcement allow antimicrobials to be obtained without oversight.
