Rising Antibiotic Resistance Threatens Children’s Health Worldwide

Global Study Reveals Widespread Increase in Resistance
A collaborative analysis led by the Murdoch Children’s Research Institute (MCRI) and the University of Sydney examined 106,581 infection samples from patients <= 18 years old in 82 countries between 2004 and 2022. Published in the *Journal of the American Medical Association*, the study found antibiotic resistance rose in every region. Gram-negative bacteria were the primary drivers, with Acinetobacter baumannii showing the highest overall resistance and Klebsiella recording the fastest growth, especially in Southeast Asia, Eastern Europe and the Western Pacific. Statistical modelling projects that by 2035 resistance to last-line carbapenems could reach 82 % for *Acinetobacter* and 35 % for *Klebsiella*.
Background and Context
Children are uniquely vulnerable to antimicrobial resistance, experiencing higher infection rates but having fewer approved antibiotic options than adults. Babies, children in intensive care, and those in lower-resource settings face the greatest risk. Historically, global surveillance has focused on adult populations, leaving a gap in child-specific data, dosing guidelines, and formulations.
Data and Statistics
- 106,581 pediatric infection samples analyzed.
- Resistance increased across all 82 surveyed countries from 2004-2022.
- Forecasts for 2035: 82 % resistance in *Acinetobacter baumannii*; 35 % in *Klebsiella*.
- In high-income regions, first-line “access” antibiotic resistance is stabilising, while “watch” and “reserve” drug resistance climbs sharply in lower-income settings.
- An estimate from 2021 links ? 840,000 deaths in children < 5 years globally to antimicrobial resistance.
Impact on Children and Healthcare
The rising resistance forces clinicians to use less common, often intravenous, antibiotics that are more expensive, harder to administer, and potentially more toxic. Harry Booth, a 13-year-old Australian with a kidney transplant, exemplifies the burden: repeated hospitalisations, bladder-cleansing procedures and prolonged IV therapy have disrupted his schooling and daily life. Such intensive treatments are becoming increasingly common as first-line drugs lose efficacy.
Official Statements & Responses
Prof Chris Blyth, paediatrician and incoming president of the Australasian Society for Infectious Diseases, described the findings as “really important work” that highlights the uneven global distribution of the problem. He noted that in low-income countries, unregulated antibiotic use and poor sanitation drive resistance, while in high-income nations, overuse in healthcare, farming and veterinary practice fuels the trend.
Verbatim Quotes
- “We are finding antibiotic resistance not just in severe diseases but in more simple, uncomplicated infections such as urinary tract infections in children,” — Penelope Bryant, MCRI associate professor
- “It highlights the real need to have global surveillance systems in place, both in Australia and internationally, to track and identify resistance,” — Prof Chris Blyth
What’s Next
The research team has launched the free AMR in Kids website, a monitoring tool that integrates two decades of data with forecasting models to identify emerging resistance hotspots through 2035. The platform aims to support clinicians, researchers and policymakers in tailoring treatment decisions and informing global surveillance strategies.
