Background on AMR

Antimicrobial Resistance; a Global Health Concern Requiring Global Governance

Antimicrobial resistance (AMR) has long been a concern dating back to the discovery of penicillin by Alexander Fleming who at his Nobel Prize acceptance speech in 1945 warned the medical community that “negligent use of penicillin” - by which he referred to under-dosage - could lead to resistance. The ensuing golden decades of discovery of new antimicrobials from 1950s to the end of 20th century - the so-called Antibiotic Era - did not eliminate the microbial threats, mainly because of misuse and overuse of antimicrobials in healthcare and livestock industry, poor sanitary conditions, inappropriate food handling and poor infection prevention and control in hospitals. And now we find ourselves in such a precarious situation facing a global tsunami of AMR that even in his prescience A. Fleming could not have predicted. With very few antibiotics in the pipeline, outdated antimicrobial research and development models and marketing practices, a constant tug of war between the Global North increasingly wary of inappropriate use of Antimicrobials, and the Global South concerned of affordable access thereto, the consequences are staggering; according to a recent report on the global burden of bacterial AMR that in 2019 there were 4.95 million deaths associated with bacterial AMR, including 1.27 million deaths directly attributable to it.

It is not all doom and gloom, however. While the global recognition of, and response to, AMR has been rather tepid for many decades, and louder in words than in action, there has been significant progress since the issuance of the WHO Resolution of the AMR Global Action Plan (GAP) in 2015. It had five objectives:

  1. improved awareness and understanding of antimicrobial resistance;
  2. strengthened knowledge and evidence base through surveillance and research;
  3. infection prevention through effective sanitation and hygiene;
  4. optimal use of antimicrobial medicines in human and animal health; and
  5. development of an economic case for sustainable investment that takes account of the needs of all countries and to increase investment in new medicines, diagnostic tools, vaccines and other interventions.

The GAP was followed by the High-Level Meeting report at the UN General Assembly in 2016 which kickstarted a flurry of activities, reports and initiatives for global advocacy, governance and action to prevent and contain AMR, and mitigate its consequences on health, healthcare, environment, animal health, poverty and the economy. These included, among others:

  1. The UN resolution in September 2016 that led to the establishment of the Inter-Agency Coordination Group (IACG) which in its report in 2019 recommended, inter alia, development and implementation of One Health Action Plans, phasing out of use of Antimicrobials in livestock for growth promotion, increased investment in new antimicrobials, and more effective global governance.
  2. AMR featuring prominently in declarations, communiques, and press releases by G7 and G20 since the very first G7 declaration on AMR in Berlin in 2015.
  3. The establishment of https://globalamrhub.org/, https://gardp.org/, https://www.phe.gov/about/barda/Pages/default.aspx, https://carb-x.org/, https://www.repair-impact-fund.com/, https://www.imi.europa.eu/ https://www.amractionfund.com/
  4. Several technical reports by the World Bank, OECD, WHO and others on AMR and its impact on health, healthcare and the economy; and more recently
  5. Country specific initiatives such as the Infection Management Control Report in the UK.

Yet what seems to be missing is an effective global governance mechanism to lead, steer, advocate for and account for progress on the ground. The existing Tripartite mechanism that brings together WHO, OIE and UNEP, while a great step forward towards the adoption and implementation of One Health, appears to be inadequate given the multiplicity of partners and stakeholders both in the public and private sphere across a range of technological challenges along the continuum, stemming from bench research on novel antimicrobials all the way to trade and economy, and future growth. The economic consequences of AMR have reached too critical a threshold to ignore. Expected losses from AMR between 2015 and 2050 may reach up to $85 trillion in GDP and $23 trillion in global trade, equivalent of up to 4% decline in global GDP by 2050, mostly among the poor in low- and middle-income countries, as a result of decline in livestock production and trade, and increase in healthcare costs. And these estimates were made before the COVID-19 pandemic with its own consequences on inappropriate use of antimicrobials, the surge in demand on public and veterinary health systems and healthcare, and the global economy.

We are at a critical juncture. We must find effective means of governance and accountability to act globally as well as locally to proactively contain AMR and mitigate its consequences through policy, oversight, metrics, surveillance and R&D. The recent evaluation of the progress with GAP made it very clear that the progress thus far has been patchy, with very few success stories in between, and the need for more effective global AMR governance.
