Home Antimicrobial Resistance (AMR) WHO outlines 40 research priorities on antimicrobial resistance

WHO has published its first global research agenda for the world’s scientists to address the most urgent human health priorities to combat antimicrobial resistance (AMR). It outlines 40 research topics on drug-resistant bacteria, fungi and Mycobacterium tuberculosis that must be answered by 2030, in line with the Sustainable Development Goals.

The WHO Global Research Agenda for AMR in human health will catalyze innovation and implementation research, spanning the epidemiology, burden and drivers of AMR, context-specific and cost-effective strategies to prevent infections and emergence of resistance.

It will also involve the discovery of new diagnostic tests and improved treatment regimens, the identification of cost-effective methods to collect data and translate it into policy, as well as how to implement current interventions more efficiently in resource-limited settings. Ultimately, the generated evidence will inform policies and interventions to strengthen the response to antimicrobial resistance, particularly in low- and middle-income countries.

“Antimicrobial resistance is an urgent public health and economic challenge, and good quality research is a vital part of the response. To help preserve antimicrobials and save lives and livelihoods, this research agenda is a crucial tool for researchers and funders to prioritize research questions, and promptly and efficiently generate evidence that informs policy,” said Dr Hanan Balkhy, WHO Assistant Director-General for AMR. “This first research agenda from WHO will provide the world’s AMR researchers and funders with the most important topics to focus on and give the world its best chance to combat AMR,” added Dr Silvia Bertagnolio, Unit Head in WHO AMR Division.

The research agenda was developed based on a review of over 3000 relevant documents published over the past decade. The review identified 2000 unanswered questions or knowledge gaps, which were further consolidated and prioritized by a large group of AMR experts to conclude with the 40 most pivotal research topics. A summary report containing the research priorities is available here.

AMR occurs when bacteria, viruses, fungi and parasites change over time and no longer respond to antimicrobial medicines making infections harder to treat and increasing the risk of disease spread, severe illness and death.

As a result, antimicrobial medicines become ineffective and infections persist in the body, increasing the risk of transmission to others. AMR remains one of the top global public health threats facing humanity and was associated with the death of close to 5 million people globally in 2019. Importantly, it is also a threat to the global economy, with impact on international trade, health care and productivity. If no action is taken, AMR could cost the world’s economy US$ 100 trillion by 2050.

Antimicrobial resistance research priorities

Water, sanitation and hygiene (WASH)

  • Investigate the impact, contribution, utility, effectiveness and cost–effectiveness of interventions to ensure safely managed water, sanitation and hygiene (including hand hygiene) and waste management practices in the community setting on reducing the burden and drivers of antimicrobial resistance, such as unnecessary antibiotic consumption for diarrhoeal diseases in low- and middle-income countries.
  • Investigate implementation strategies of WASH-related interventions in health-care settings (including ensuring access to safely managed water and sanitation, safe hand hygiene, safe management of waste and environmental cleaning), and assess their impact, acceptability, equity and cost–effectiveness on the burden and transmission of resistant health care–associated infections and antimicrobial medicine prescribing across socioeconomic settings.

Infection, prevention and control

  • Identify the most effective, cost–effective, acceptable and feasible multimodal infection and prevention control strategies (such as hand hygiene, contact precautions and patient isolation) and the relative effect of their components in reducing different types of health care–associated infections caused by multidrug-resistant pathogens across geographical and socioeconomic settings.


  • Assess the impact of vaccines on preventing colonization and infection by resistant pathogens (whether specifically targeted by the vaccine or not) and on reducing the overall use of antimicrobial medicines, health-care encounters and health system costs among adults and children, and across socioeconomic settings.

Diagnosis and diagnostics

  • Investigate and evaluate rapid point-of-care diagnostic tests (including biomarker-based tests) and diagnostic algorithms to discriminate between bacterial and viral infections and non-infectious syndromes that are feasible for use in limited-resource settings and among different subpopulations (including children and neonates).
  • Investigate and evaluate phenotypic and genotypic methods of rapid antimicrobial susceptibility testing and resistance detection directly from positive blood culture bottles, especially for use in low- and middle-income countries.
  • Investigate and evaluate diagnostic tests for isolating, identifying, antimicrobial susceptibility testing and/or detecting resistance of bacterial pathogens (including multiplex panel–based tests and tests using novel technologies) that are fast, (near) point of care, affordable, feasible for use in limited-resource settings and among different subpopulations and from a variety of specimen types.
  • Investigate and evaluate rapid, (near) point-of-care diagnostic tests (including antigen and multiplex panel–based tests) for detecting drug-resistant WHO fungal priority pathogens with critical importance for antimicrobial resistance (such as Candida auris, Aspergillus fumigatus and Cryptococcus neoformans) feasible for use in limited-resource settings and among different subpopulations.
  • Investigate and evaluate the clinical utility and diagnostic accuracy of phenotypic antifungal susceptibility testing (including determining minimal inhibitory concentration breakpoints and testing for in vitro and in vivo synergy between antifungal medicines) and their impact on clinical outcomes.
  • Investigate, assess the performance and evaluate the implementation of novel rapid point-of-care molecular and non- molecular assays and optimal testing and screening approaches (including self-testing) for Neisseria gonorrhoeae and antimicrobial resistance detection to reduce inappropriate antibiotic prescribing and emergence of antimicrobial resistance.

Treatment and care
Antimicrobial stewardship

  • Investigate antimicrobial stewardship interventions (such as implementing the WHO AWaRe antibiotic book,11 guidelines, clinical algorithms, education and training, audit and feedback), alone or in combination, that are context specific, feasible, sustainable, effective and cost-effective to avoid antimicrobial misuse in outpatient and inpatient settings, especially where diagnostic capacity may be limited.
  • Identify feasible, effective and scalable pharmacist antimicrobial medicines dispensing practices in community pharmacies and related regulatory frameworks (such as incentives and disincentives) to improve antimicrobial stewardship in the community, especially in low- and middle-income countries.
  • Investigate criteria and strategies to optimize empirical antimicrobial therapy (such as antimicrobial spectrum, dose, timing of initiation, de-escalation, and stopping), weighting the benefits (e.g., improve outcomes, reduce cost) versus potential harms (e.g., clinical failure, infection relapse, resistance emergence, adverse events), for main community and health care-associated infectious syndromes in adults and children, especially in settings where medicine availability, diagnostic capacity and access to health care services may be limited.

Antimicrobial use and consumption
