Imagine going to the hospital for a bacterial ear infection and hearing your doctor say, “We’re out of options.” It may sound dramatic, but antibiotic resistance is pushing that scenario closer to becoming reality for an increasing number of people. In 2016, a woman from Nevada died from a bacterial infection that was resistant to all 26 antibiotics that were available in the United States at that time.
The US alone sees more than 2.8 million antibiotic-resistant illnesses each year. Globally, antimicrobial resistance is linked to nearly 5 million deaths annually.
Bacteria naturally evolve in ways that can make the drugs meant to kill them less effective. However, when antibiotics are overused or used improperly in medicine or agriculture, these pressures accelerate the process of resistance.
As resistant bacteria spread, lifesaving treatments face new complications – common infections become harder to treat, and routine surgeries become riskier. Slowing these threats to modern medicine requires not only responsible antibiotic use and good hygiene, but also awareness of how everyday actions influence resistance.
Since the inception of antibiotics in 1910 with the introduction of Salvarsan, a synthetic drug used to treat syphilis, scientists have been sounding the alarm about resistance. As a microbiologist and biochemist who studies antimicrobial resistance, I see four major trends that will shape how we as a society will confront antibiotic resistance...
