Overview

Narrative review reveals escalating antimicrobial resistance caused 1.27 million direct deaths globally in 2019, highlighting the imminent risk of entering a post-antibiotic era without policy action.

Key Points

  • Synthesize global evidence on the disease burden, biological and environmental drivers, economic consequences, and systemic solutions associated with escalating antimicrobial resistance.
  • Synthesized global surveillance and research data from 2000 through early 2026, incorporating Global Research on Antimicrobial Resistance (GRAM) datasets and World Health Organization records.
  • Evaluated One Health drivers spanning human clinical prescribing, agricultural livestock consumption, and environmental water contamination alongside macroeconomic projection models.
  • Bacterial resistance caused 1.27 million direct deaths and contributed to 4.95 million total deaths in 2019, with the highest burden concentrated in low- and middle-income countries.
  • Identified primary systemic drivers, including 70% of global antibiotic consumption occurring in agriculture, 30% inappropriate prescribing in high-income settings, and resistance genes present in 72% of rivers.
  • Documented near 50% intensive care unit mortality from critical ESKAPE pathogens, with macroeconomic forecasts estimating global annual GDP reductions between 1.1% and 3.8% (up to approximately 5%) by 2050.
