Report Date: 2021

Launched by the World Health Organization (WHO) in 2015 to support the strengthening of the antimicrobial resistance (AMR) evidence base, the Global Antimicrobial Resistance and Use Surveillance System (GLASS) is the first system that enables harmonized global reporting of official national AMR and antimicrobial consumption (AMC) data. The report highlights the new technical module on AMC surveillance, which provides a common, standardized set of methodologies for measuring and reporting the consumption of antimicrobial medicines at country, regional, and global levels. The report also describes developments over the past years in other surveillance programs led by WHO, including resistance to anti-human immunodeficiency virus (HIV) and anti-tuberculosis (TB) medicines, antimalarial drug efficacy, and environmental surveillance of AMR.
