Abstract
Antimicrobial resistance (AMR) is a recognised global threat to health security. However, mainstream responses to this threat to public policy have remained elusive, and anti-AMR measures have been limited to health interventions. AMR is caused by global factors, including sustained and irresponsible antibiotic use in humans and animals, as well as climate change. Hence its effective management also requires global collaborative efforts. This policy brief provides an overview of AMR, its significance, and the current landscape of policies, national action plans, and funding for AMR research and surveillance within the G20 countries. It also highlights the need for concerted action and international cooperation to address this critical issue.
