## Key takeaways

- Resistance is evolution under exposure: every course of antibiotics, needed or not, selects for the bacteria that survive it.
- The pipeline problem is economic, because a new antibiotic used sparingly cannot repay its development under normal drug pricing.
- Individual behaviour still matters: not pressing for antibiotics for viral illness, and vaccination that prevents infection, both reduce the selection pressure.

Modern medicine rests on a quiet assumption: that bacterial infection is a solved problem. Surgery, chemotherapy, caesareans, transplants and the treatment of everyday wounds all presume antibiotics will work afterwards. Antimicrobial resistance is the slow withdrawal of that assumption, and global estimates already attribute over a million deaths a year directly to resistant infections, with several million more associated. The projections that made headlines, resistance rivalling cancer as a killer by mid-century, were not science fiction but extrapolation.

The mechanism is evolution operating exactly as described. Bacteria reproduce in minutes and mutate constantly. An antibiotic kills the susceptible; any survivor carrying a resistance trait inherits the vacated territory, and bacteria compound the problem by trading resistance genes between species. Every exposure selects for survival, which reframes the everyday transaction most people have with these drugs. The course taken for a viral chest infection it could never treat, the broad-spectrum drug used where a narrow one would serve, the animals dosed for growth in farming systems: none is an isolated waste, each is a small evolutionary vote for the wrong side. Roughly a fifth of antibiotic prescriptions in English primary care have been estimated as unnecessary, which is why prescribing has tightened and why the GP who declines to prescribe for a cold is following the evidence rather than rationing.

## Why new drugs do not simply arrive

The natural response, invent more antibiotics, has run into economics rather than chemistry. A genuinely novel antibiotic would rightly be held in reserve, used rarely to preserve its power. Under normal pharmaceutical pricing, a drug that must not be sold in volume cannot repay its development, so most large companies left the field decades ago and the pipeline thinned to a trickle of variations on existing classes. The fixes now being trialled invert the deal: subscription models, pioneered in the UK, pay developers a flat annual fee for access to a new antibiotic regardless of quantity used, decoupling revenue from volume. It is the rare health policy that treats a medicine like a fire extinguisher, valued for existing rather than for being used.

Individual actions map neatly onto the mechanism. Take antibiotics exactly as prescribed when they are needed; do not press for them when a clinician says the illness is viral; never share or hoard leftover courses. Vaccination belongs on the list for an underrated reason: every infection prevented, viral or bacterial, is antibiotic demand that never occurs. Hand hygiene and food safety cut transmission of resistant strains as effectively as of any other kind.

Resistance will never be abolished, because evolution does not stop. The achievable goal is a permanent stalemate, in which stewardship, surveillance and a refilled pipeline keep the drugs ahead of the bacteria. The emergency's defining feature is its speed, slow enough to ignore in any given year, which is precisely how solved problems come apart.
