How AI Could Help Combat Antibiotic Resistance

AI Could Change the Antibiotic Resistance Fight, but Access May Be the Hard Part

AI could speed diagnosis of drug-resistant infections that currently take days to confirm.
Fast diagnostics matter because delayed treatment raises risk in severe infections such as sepsis.
Deployment and incentive problems may be as important as the technology itself.
