In a concerning revelation, a recent study led by the University of Sydney has exposed the diminishing effectiveness of antibiotics in treating common infections in children worldwide. The study highlights the critical issue of antibiotic resistance and its impact on the health of children, emphasizing the urgent need for updated global antibiotic guidelines.

Antibiotic Resistance in Children: The research indicates that many antibiotics recommended by the World Health Organization (WHO) are now less than 50% efficient in treating childhood diseases such as pneumonia, sepsis, and meningitis. This alarming trend raises questions about the adequacy of current global antibiotic guidelines and their relevance in the face of evolving bacterial resistance.

Global Impact: The regions most severely affected by this antibiotic resistance crisis are Southeast Asia and the Pacific, particularly near Indonesia and the Philippines. Shockingly, thousands of children in these areas succumb to avoidable deaths due to antibiotic-resistant infections each year. The World Health Organization recognizes antimicrobial resistance (AMR) as a significant global public health risk.

Key Findings: Published in the Lancet South East Asia, the study underlines the growing evidence that common bacteria causing sepsis and meningitis in children are increasingly resistant to medications. Notably, the antibiotic ceftriaxone, widely used for various pediatric diseases, was found to be effective in only one out of every three instances of infant sepsis or meningitis.


Dr Phoebe Williams, an infectious disease specialist and dedicated researcher at the University of Sydney, has been at the forefront of unravelling the escalating challenge posed by multidrug-resistant bacterial illnesses in children on a global scale. With a profound focus on understanding and combating infectious diseases, Dr Williams sheds light on the alarming trend of these bacterial infections becoming increasingly resistant to multiple drugs.

In her extensive research, Dr Williams underlines a concerning reality: children, in comparison to adults, are more vulnerable to Antimicrobial Resistance (AMR). This vulnerability comes from the fact that new antibiotics are less likely to be rigorously tested and made readily available for the pediatric population. The limited range of effective antibiotics for children worsens the impact of AMR on their health.

The study serves as a wake-up call to the global community, urging immediate attention to combat antibiotic resistance in childhood infections. Dr. Williams emphasizes the need for increased funding to investigate new antibiotic treatments specifically designed for children and newborns. To address the rising antibiotic resistance in children, Dr. Williams recommends prioritizing research funding for new antibiotic treatments. She points out that the focus has traditionally been on adults, leaving children and newborns with limited treatment options.


Dr Williams is currently exploring the potential of an old antibiotic, fosfomycin, as a temporary solution to treat multidrug-resistant urinary tract infections in children in Australia. Additionally, she collaborates with the WHO's Paediatric Drug Optimization Committee to ensure timely access to antibiotics for children, aiming to reduce deaths due to AMR.


The study's findings shed light on the critical challenges surrounding the availability of effective antibiotics for treating serious infections in children. Urgent action is needed to address antibiotic resistance, safeguard the health of our children, and prevent unnecessary deaths due to AMR
