What is antimicrobial resistance (AMR)?
Antimicrobial resistance is the ability of a microorganism (like bacteria, viruses and some parasites) to stop antimicrobials (such as antibiotics, antivirals, and antimalarials) from working against it. As a result, standard treatments become ineffective, infections persist and may spread to others.* AMR can affect anyone, of any age, in any country.
How does it happen?
There is usually a small number of bacteria that are resistant to antibiotics→
antibiotics kill bacteria causing the illness - but they also kill the good bacteria that protects the body from
The drug-resistant bacteria survive and multiply→
Eventually, the drug-resistant bacteria becomes dominant and spreads
