Antimicrobial Resistance (AMR) occurs when bacteria, viruses, fungi and parasites change over time and no longer respond to medicines making infections harder to treat and increasing the risk of disease spread, severe illness and death. How big a problem is that?
There were an estimated 4·95 million deaths associated with bacterial AMR in 2019. A paper published earlier this year by the Antimicrobial Resistance Collaborators in The Lancet aims to quantify the size of the problem. The authors used a variety of data sources including systematic literature reviews, hospital system data, surveillance systems, and other sources.
