New Zealand Case Report Warns Medical Misinformation Can Delay Children’s Treatment, Leading to Life-Threatening Complications
A case report published by New Zealand doctors has raised fresh concerns about the growing impact of medical misinformation on children’s health, after a nine-year-old girl developed serious, life-threatening complications because her parents did not follow prescribed antibiotic treatment for a cat scratch infection and instead used silver nitrate at home. The case, described in the New Zealand Medical Journal, highlights how parental hesitancy, influenced by false and misleading information circulating online and elsewhere, can have dangerous consequences for young patients who have no say in the medical decisions made on their behalf. According to the authors, the girl’s condition deteriorated to the point where she required surgery and a six-week course of intravenous antibiotics. The report’s authors argue that clinicians should have open, empathetic, and non-judgmental conversations with parents about their children’s treatment plans, and that such discussions are essential to reducing parental hesitancy and rebuilding trust in evidence-based medicine. The case is being presented as a stark reminder that misinformation is not a harmless online phenomenon but a real-world threat that can undo decades of medical progress.
Dr Morgan Arnold, an Ophthalmology Registrar at Health New Zealand and one of the authors of the case study, said the report was both relevant and important in the current climate of widespread medical misinformation. “As misinformation continues to be propagated both globally and domestically, trust in society as a whole is eroded,” she said. “This trust is important in many areas of our lives but perhaps none more so than the medical field.” Arnold emphasised that the people who pay the biggest price when trust in medicine collapses are the most vulnerable members of the population, especially children. In this case, a New Zealand child developed Pott’s Puffy Tumour, a rare life-threatening complication of frontal sinusitis that has become uncommon in the modern antibiotic era but is now resurging as some families turn away from proven treatments. Arnold drew parallels with the return of diseases such as syphilis and measles, which have reached levels not seen in this millennium. “Like Pott’s Puffy Tumour, this disproportionately affects the young in our society who have no capacity or agency to make their own decisions about antibiotics, vaccinations and medical information,” she said. She added that the report points to where change can begin, with medical professionals, their discussions with patients, and the institutions they form to protect the public.
However, Dr John Kerr, a Senior Research Fellow in the Department of Public Health at the University of Otago, cautioned that misinformation alone may not be the full explanation for the parents’ decision. While the ophthalmologists involved in the case attributed the decision to “medical misinformation,” Kerr argued that it is often more complex than simply believing a false claim seen online. “We often think of ‘misinformation’ as discrete bits of information, like a false claim in a Facebook post or a misleading online video,” he said. “In this case, there also appears to be some parental distrust of the medical system as a whole. Misinformation and the online ‘rabbit hole’ may have played a role, but there might be other factors in the mix, such as previous negative experiences with the health system or government institutions.” Kerr suggested that a simple starting point for clinicians is to be aware of common misinformed beliefs in their area of medicine and to be prepared to discuss them openly with patients. He pointed to evidence-based recommendations for having these difficult conversations, including being open-minded and empathetic, validating broader values such as critical thinking and healthy skepticism, while gently rebutting specific false claims. Kerr also stressed that social media companies should not be let off the hook. “There’s tons of medical bullshit being promoted on these platforms, and big tech companies could and should be doing more to prevent it,” he said.
Associate Professor Siouxsie Wiles, a microbiologist at the University of Auckland, said the case shows how quickly misinformation and disinformation can turn a treatable infection into a life-threatening illness. “In this particular case, a child’s parents rejected the standard evidence-based treatment for a simple infection – a short course of oral antibiotics. Instead they chose to treat the infection using silver nitrate,” she said. “It didn’t work and left their child with a life-threatening infection that required surgery and a six-week course of intravenous antibiotics to resolve.” Wiles noted that silver does have antibacterial properties and has historically been used to treat burns, ulcers, and infected wounds, but it is also highly caustic and can damage healthy tissue and skin. That is one reason it fell out of favour once antibiotics became available. Yet the internet, she said, is full of false and misleading information promoting it. She called for better regulation of online spaces that share and amplify medical misinformation. Wiles also highlighted that the child in the case was unvaccinated, and noted that there are many reasons children may not be up to date with routine immunisations. “From a lack of access to routine healthcare to a lack of parental trust caused by a lifetime of difficult and/or harmful interactions with official organisations and agencies,” she said. Providing medical professionals with resources to have empathetic conversations with patients and caregivers about their beliefs and feelings regarding evidence-based medicine, she added, may help prevent further cases like this one.
Associate Professor Stephen Hill, a psychologist at Massey University, said one of the most striking aspects of the case is that even relatively low levels of medical hesitancy can result in significantly increased health risks and much greater demands on medical services. “Happily, the child involved appears to have recovered from their ordeal, and, despite initial resistance, their parents allowed medical professionals to administer the necessary treatment when it became clear that the child’s health had deteriorated,” he said. But the cost to the family and to the health system was far higher than it needed to be. Hill noted that it is not entirely clear from the case report exactly how misinformation was implicated, but reading between the lines, a general suspicion or uncertainty about mainstream medicine likely led to both a failure to take expert advice seriously and a belief that alternative options would be sufficient. He described this as a common “low key” consequence of misinformation that tends to fly under the media radar, despite the significant cumulative psychological, physical, and societal costs involved. He distinguished between deliberate disinformation campaigns, such as Andrew Wakefield’s false claims about the MMR vaccine, and the more subtle, often unintentional spread of incorrect claims that sow mistrust. This “misinformation-by-stealth,” he said, works by increasing uncertainty about who to trust regarding health matters, making people hesitant about following expert advice.
Hill warned that the greatest danger of misinformation is not necessarily that a single false claim will persuade people to act inappropriately, but rather that information ecosystems become opaque and difficult to navigate. In such an environment, it becomes harder to distinguish scientifically credible claims from those that are not, and people can drift, almost inadvertently, into risky health behaviours. Addressing this, he argued, requires a multipronged response. The first challenge is to adequately resource frontline health professionals to deal respectfully and empathetically with people who are already hesitant, uncertain, or misinformed. The second challenge is to create a better information ecosystem so that people are less likely to become hesitant and mistrusting in the first place. This means making it easier for people to access reliable and accurate information, and helping them understand misinformation when they see it. Hill called for institutional and regulatory changes so that unproven treatments are not packaged to look like real medicines and therapies, as well as frequent public correction and refutation of misinformation, and well-funded health literacy education. Ultimately, the case serves as a sobering reminder that medical misinformation is not a abstract issue confined to social media feeds, but a tangible danger that can cost children their health and place enormous strain on families and healthcare systems. The experts agree that rebuilding trust in medicine will require patience, empathy, honest conversation, and stronger accountability from the platforms that allow misinformation to flourish.
