What is AMR? Antimicrobial resistance (AMR) occurs when microorganisms adapt after exposure to antimicrobial drugs… Continue reading The economics of antimicrobial resistance and the role of water and sanitation services

The Minoans understood that piped water on… Continue reading Incremental benefits from increases in sanitation service level
