Fast-forward to September 2024 and researchers have predicted that 39 million people will die of drug-resistant infections between 2025 and 2050.
Annual deaths will increase by 70% over this quarter-century, to 1.9 million deaths a year by 2050, according to The Global Research on Antimicrobial Resistance Project.
