Introduction Antimicrobial resistance (AMR) is compromisingthe effectiveness of life-saving treatments,posing a serious, growing threat to globalhealth and undermining the foundations ofmodern medicine. In response, World HealthOrganization (WHO) established the GlobalAntimicrobial Resistance and Use SurveillanceSystem (GLASS) to strengthen evidence on AMRthrough standardized data collection, analysis,sharing and reporting. Launched in 2015 tomonitor AMR and extended in 2020 to includeantimicrobial use (AMU), the system receivesdata on AMR from the human health sectoron infections of both hospital and communityorigin. The findings are concerning. Resistance toessential antibiotics – particularly among Gram-negative bacteria – is widespread, increasing andunevenly distributed. The effectivene
