· MDR organisms are of particular concern. MDR bacteria have developed resistance to one or more of the antibiotics used to treat them. Multi‐drug resistance in an organism may develop when antibiotics are not used properly. 1 Taking antibiotics for the incorrect duration or using antibiotics when they are not needed, such as for viral

· Background Antimicrobial resistance (AMR) among bacteria is an escalating public health emergency. An estimated 1.27 million deaths were attributed to bacterial AMR in 2019. 1 If left unchecked, AMR may lead to an estimated 10 million deaths each year by 2050. 2 Moreover, there have been dramatic global increases in AMR

Antimicrobial Resistance (AMR) occurs when bacteria, viruses, fungi and parasites no longer respond to antimicrobial medicines. As a result of drug resistance, antibiotics and other antimicrobial medicines become ineffective and infections become difficult or impossible to treat, increasing the risk of disease spread, severe illness, disability
