Antimicrobial resistance
Antimicrobial resistance (AMR) is resistance of a microorganism—bacteria, viruses and some parasites—to an antimicrobial medicine—such as antibiotics, antivirals, and antimalarials—so that standard treatments become ineffective and infections persist and may spread to others to which it was previously sensitive.
AMR is a consequence of the use, particularly the misuse, of antimicrobial medicines and develops when a microorganism mutates or acquires a resistance gene. Other factors also increase the magnitude of the problem, such as the use of antibiotics in agriculture and animal consumption, and fragile programs on Infection Prevention and Control.
