Invisible killer: What is antimicrobial resistance?

Antimicrobial resistance (AMR) is an invisible killer, which is directly responsible for 1.3 million deaths and a contributing factor to five million other fatalities every year. Everyone seems to have had a family member or friend who has either gotten seriously ill or died due to acquiring an infection that did not respond to prescribed medicines, and the underlying reason was often antimicrobial resistance. Yet, there are many ways of addressing this threat, from hygiene and sanitation to vaccination and avoiding overuse or misuse of medicines.
