The world is heading towards widespread resistance to common antibiotics. The Global Antibiotic Resistance Surveillance Report 2025, which was launched today by the World Health Organization (WHO), warns that increasing resistance to essential antibiotics poses a growing threat to public health systems globally, especially in countries least equipped to handle it.
Alarming trends in antibiotic resistance
Data submitted by 104 countries to the WHO Global Antimicrobial Resistance and Use Surveillance System (GLASS) reveals that between 2018 and 2023, bacterial resistance to 40% of monitored antibiotics rose by 5–15% annually. Drawing from more than 23 million bacteriologically confirmed infections, the report estimates that 1 in 6 common bacterial infections globally were resistant to antibiotic treatment in 2023.
The report analyses resistance to 22 critical antibiotics used to treat urinary tract, gastrointestinal, and bloodstream infections, as well as gonorrhea. These first-line treatments are losing effectiveness, increasingly forcing healthcare providers to resort to intravenous therapy and “last-resort” antibiotics – which are costlier, harder to access, and frequently unavailable in low- and middle-income countries.
Regional disparities
Antibiotic resistance is not evenly distributed across the globe:
– Highest resistance rates were observed in Southeast Asia and the Eastern Mediterranean, where 33% of the bacterial infections were resistant.
– In the African Region, 1 in 5 infections showed resistance.
– By contrast, resistance levels were lowest in Europe (1 in 10) and the Western Pacific (1 in 11).
The disparities reflect underlying differences in healthcare systems, surveillance capabilities, and access to medicines.
Gram-Negative Bacteria: The Leading Threat
WHO warns that gram-negative bacteria – notoriously difficult to treat – pose the greatest danger. E. coli and Klebsiella pneumoniae are now the leading drug-resistant pathogens in bloodstream infections. These bacteria often lead to sepsis, organ failure, and death.
Over 40% of E. coli strains and 55% of K. pneumoniae strains are now resistant to third-generation cephalosporins, the primary antibiotics used for treatment. In the African Region, resistance exceeds 70% for both pathogens.
Other key pathogens, including Salmonella, Acinetobacter, and N. gonorrhoeae, are also developing resistance to carbapenems and fluoroquinolones, further narrowing treatment options.
Pathogen Resistance Snapshots (2023)
Cephalosporin-resistant E. coli
– Major cause of urinary and bloodstream infections.
– Global resistance in bloodstream infections: 45%
– Highest in African Region: 71%
Carbapenem-resistant K. pneumoniae
– A deadly hospital-acquired superbug.
– Bloodstream infection resistance: 17% globally (increase of 15% annually)
– Urinary tract infection resistance: 11% globally (increase of 13% annually)
– Imipenem resistance is highest in SE Asia: 41% (bloodstream), 31% (UTIs)
Methicillin-resistant Staphylococcus aureus (MRSA)
– Spreads across hospitals, communities, and farms.
– Global resistance in bloodstream infections: 27%
– Highest in Eastern Mediterranean: 50%
Fluoroquinolone-resistant Salmonella spp.
– Leading cause of food-borne infections.
– Ciprofloxacin resistance: 18% (bloodstream), 16% (GI infections)
– Highest in Europe: 36% (bloodstream), 24% (GI)
Drug-resistant N. gonorrhoeae
– High global incidence and asymptomatic transmission.
– Ciprofloxacin resistance: 75% globally, 88% in SE Asia
– Ceftriaxone resistance remains low, but data are limited.
Progress in surveillance, but major gaps remain.
Since GLASS was launched in 2016, country participation has grown from 25 to 104 countries by 2023, showing increased global commitment to tackling AMR. However:
* 48% of countries did not submit any data in 2023.
* Nearly half of reporting countries lack robust data systems.
* Even though participation from Southeast Asia was highest, with 91% of the countries in that region reporting data, surveillance coverage was the lowest in this region, as well as in the African region.
* Surveillance coverage was highest in Europe and the Western Pacific regions. Surveillance coverage was highest in Europe and the Western Pacific regions.
Countries with weak surveillance and low income levels consistently show higher resistance rates, highlighting a vicious cycle where limited capacity to monitor and respond to AMR fuels its spread. The burden of AMR is not evenly distributed. It is heaviest in countries with weaker health systems and lower income levels, limited diagnostic capacity, and restricted access to effective and essential antibiotics. This shows that limited capacity to prevent, diagnose, and treat infections contributes to higher resistance.
Dr Silvia Bertagnolio, Unit Head for Surveillance, Evidence and Laboratory Strengthening in WHO’s AMR Division, shared that “When we looked at the relationship between AMR and income and universal health coverage indicators in over 95 countries, we found that antibiotic resistance proportionately affects low middle-income countries with weak health systems. So, countries facing the greatest burden often have the least capacity to assess their AMR situation. This means that the smaller countries can monitor resistance; the more resistance they tend to have. Without strong surveillance, resistance spreads unchecked.”
But she adds a word of caution: “higher level of resistance in countries with poor surveillance systems could also be influenced by an overrepresentation of tertiary hospitals where severe cases are, and therefore inflating the resistance level.”
Prevention is key: The way forward.
According to Dr Yvan Hutin, Director of WHO’s AMR Division, the solution lies in prevention: “If infections do not happen, resistance does not arise. That’s why we must prioritize WASH – water, sanitation, and hygiene – and vaccination.”
He emphasizes scaling up access to existing vaccines (like pneumococcal and rotavirus vaccines), accelerating development of new ones, and investing in public health infrastructure to stop infections before they begin.
He also stresses public awareness: “Not every fever needs an antibiotic. If your doctor does not prescribe one, that often means it is a viral infection – and that is actually good clinical judgment.”
Dr Hutin rightly warns: “As antibiotic resistance continues to rise, we are running out of treatment options and putting lives at risk, especially in countries where infection prevention and control are weak and access to diagnostic and effective medicine is already limited. The fewer people who have access to quality care, the more they are likely to suffer from drug-resistant infections.”
AMR: A present danger and a looming crisis
Antimicrobial Resistance (AMR) is already killing millions: In 2021, bacterial infections caused an estimated 7.7 million deaths. 4.71 million of them were linked to AMR, and 1.14 million deaths were directly attributed to resistant infections.
WHO warns that excessive, inappropriate use of medicines like antibiotics, antivirals, antifungals, and antiparasitics could accelerate the AMR crisis beyond control. Access must be balanced with stewardship – overuse today means no cure tomorrow.
Global commitments and the path ahead
The political declaration on AMR adopted at the United Nations General Assembly High-Level Meeting in 2024 provides a roadmap for action. It urges countries to:
– Strengthen health systems and surveillance infrastructure
– Invest in infection prevention and control (IPC)
– Scale up vaccination, diagnostics, and laboratory capacity
– Optimise treatment protocols and preserve existing antimicrobial medicines
– Implement a One Health approach, integrating human, animal, and environmental health efforts.
Antimicrobial resistance is not just a looming public health emergency – it is already here. Without urgent, coordinated global action, we risk entering a future where even minor infections could once again become deadly.
Let us protect all antimicrobial medicines we still have – by using them wisely, monitoring resistance closely, and preventing infections before they happen.
