A credit transfer system is, at its core, an accounting mechanism for learning. It records verified educational achievements so that a course completed at one institution can be recognized at another, supporting lifelong learning in an economy where skills rapidly become obsolete. Similar systems have been tried internationally, from the European Credit Transfer and Accumulation System to South Korea’s Academic Credit Bank and proposals for aligned Asian academic credits. Yet the Chinese version is distinctive in scale and in the complexity of its governance: it must coordinate individual learners deciding whether to participate, schools deciding how much to invest in compatible teaching resources, and a government deciding how aggressively to supervise and subsidize the enterprise. Each actor’s payoff depends on what the others do, which is precisely the situation game theory was built to describe.

He and Bu constructed a three-subject dynamic evolutionary game model. In an evolutionary game, agents are not treated as perfectly rational calculators who instantly find the best move; instead, populations of players adjust their strategies over time, with more successful strategies spreading through imitation and reinforcement. The approach, which traces back to Lewontin’s application of game theory to evolutionary biology and has since become standard in economics, is well suited to education policy, where participants learn, imitate, and adapt rather than optimize from the start. The researchers incorporated external constraints, strategic assumptions, and payment assumptions into the model, grounding the payoff structure in the benefit relationships among the stakeholders.

The model assigns each player a binary strategic choice. Learners can adopt strong participation, actively engaging with the system to improve their abilities, or hold back. Schools can participate actively by building high-quality teaching resources that feed the credit system, or invest minimally. The government can exert strong dominance through supervision and support, or take a laxer stance. Each choice carries costs and expected benefits: learners pay tuition and effort in exchange for portable credentials and improved skills; schools bear the expense of developing quality courses and administrative compatibility in exchange for enrollment, reputation, and possibly government incentives; the government funds oversight and subsidies in exchange for social returns such as a better-trained workforce.

To move beyond abstract equilibrium conditions, the authors ran numerical simulations of the model. Simulations of this kind allow researchers to trace how the probability of each strategy changes over successive rounds, revealing the decision-making mechanism of the three parties under different parameter settings. The exercise is particularly valuable because the equilibria of evolutionary games depend sensitively on cost allocations and benefit magnitudes; a system that looks stable on paper can collapse if, for example, the cost of building compatible teaching resources falls entirely on schools while the benefits accrue mostly to learners and the state.

The central finding is a matching rule. The optimal configuration for constructing a suitable credit transfer system combines strong participation by learners focused on ability improvement, active participation by schools in creating high-quality teaching resources, and strong dominance by the government in supervision and support. In other words, no single actor can carry the system: learner enthusiasm without quality courses produces credentials with little content, and quality resources without learners generate waste, while absent government supervision undermines trust in the credits themselves. The system functions as a three-legged stool, and the evolutionary dynamics determine whether all three legs stabilize simultaneously.

The analysis also illuminates why credit transfer efforts elsewhere have struggled. International experience, from pan-European grading scales to attempts at equivalency between the European credit systems for higher and vocational education, shows that technical compatibility is only part of the problem; incentives matter just as much. The Chinese study suggests that misalignment of cost and benefit among stakeholders, rather than flaws in credit accounting itself, may explain stalled adoption. When the government’s supervision and support are strong enough to shift expected payoffs, the simulations indicate that learners and schools can be tipped into the cooperative strategies that make the whole arrangement viable.

Methodologically, the paper illustrates a growing trend in education research: importing formal tools from economics and biology to model policy systems with many interacting agents. The authors draw on stakeholder theory, which originated in management science with Donaldson and Preston’s influential formulation, to justify the three-party structure, and then embed it in a replicator-style dynamic framework. Numerical simulation serves as the bridge between analytic equilibrium conditions and practical policy levers, letting the researchers ask counterfactual questions about what happens when costs are reallocated or benefit demands change.

For policymakers, the practical implications are concrete. Investment in high-quality teaching resources should be encouraged so that schools find active participation genuinely rewarding, and government supervision should be robust enough to certify credit quality, since the value of any transferable credit rests on trust in its standards. Meanwhile, the design should make ability improvement, not merely credential collection, the visible payoff for learners, aligning individual motivation with the system’s educational purpose. The work was supported by China’s National Program for Funding Postdoctoral Researchers, and both authors are affiliated with Beijing Normal University.

As lifelong learning becomes an economic necessity in an era of rapid technological change, credit transfer systems are likely to spread globally, and the Chinese experience will be watched closely. He and Bu’s evolutionary game model provides a template for anticipating how such systems behave before they are built: identify the players, quantify their costs and benefits, simulate the dynamics, and design interventions that steer all parties toward the cooperative equilibrium. The finding that strong learner participation, active school engagement, and strong government dominance must arrive together is a warning against piecemeal reform, and a demonstration that the mathematics of strategic interaction can inform one of education’s most intricate institutional projects.

The dimensions of the problem are not confined to the clinic. Digital spaces and online platforms have introduced new and complex risks with direct mental health consequences, including cyberbullying, exposure to harmful content and patterns of excessive or unregulated use that can erode sleep, attention and self-esteem. These pressures are compounded in Malaysia by persistently high levels of stigma surrounding mental illness, and by longstanding social and structural inequalities that leave some groups of young people far more exposed than others. Despite the evident urgency, youth-focused mental health research in the country remains scarce, and gaps persist in both policy frameworks and in services specifically designed to reach adolescents and young adults. The result is a widening distance between a rapidly evolving burden of disease and the systems meant to address it.

A research initiative now underway in neighbouring Cambodia and Vietnam offers a possible template for closing that gap. The Mental health capacity Building and stRengthening In Global HealTh systems, or M-BRIGHT, study is designed to build capacity for youth-targeted mental health services in settings where specialist clinicians are in short supply. Its architecture rests on four key elements. First, the intervention is co-adapted with young people aged fourteen to eighteen alongside teachers, government representatives, non-governmental organisations and faith leaders, ensuring that what is delivered reflects the realities and values of the communities involved. Second, the intervention is delivered in schools, embedding support in an institution young people already attend. Third, capacity is built among non-specialists, including teachers, so that delivery does not depend on scarce clinical staff. Fourth, the approach is embedded and scaled up through sustained multi-sectoral stakeholder engagement rather than remaining a stand-alone research project.

In May 2026, this model was brought directly into conversation with Malaysia. M-BRIGHT researchers, together with the United Nations University–Global Health, co-convened a stakeholder engagement and priority-setting workshop in Kuala Lumpur to discuss the M-BRIGHT approach and explore how it might be adapted to a Malaysian context. The gathering was unusually broad in composition. It drew together government representatives from the Ministries of Health, Education and Digital, alongside participants from the private sector, non-governmental organisations, United Nations agencies, academia and clinical practice. Over the course of the workshop, participants examined youth mental health trends, risk factors, existing programmes, service gaps and priority concerns, and considered lessons emerging from M-BRIGHT’s work elsewhere in the region. One observation surfaced repeatedly: while some local programmes are demonstrably effective, infrastructural challenges must be addressed if their reach and sustainability are to improve.

From those discussions, five interrelated priority areas crystallised. The first concerned target groups. Although young people aged ten to eighteen were widely recognised as the priority population for mental health research and programming, participants stressed that particular attention may be needed for those easiest to overlook: youth who are out of school, young people living in challenging home environments, refugees, vulnerable minorities and undocumented children. These are precisely the groups least likely to be captured by school-based screening or to present voluntarily at clinics, and their invisibility in routine data compounds the risk that services are designed around the needs of the most visible rather than the most vulnerable.

The second priority area defined the focus of future programming and research. Participants identified specific topic areas demanding attention, including eating disorders, adverse childhood experiences, suicide, and risky sexual and social behaviours. They also emphasised digital spaces, framing them in dual terms: as drivers of youth mental ill-health, and simultaneously as an opportunity, a channel through which prevention, literacy and support could be delivered at scale. The third strand centred on prevention itself, including early intervention and the promotion of mental health literacy, so that problems are recognised and addressed before they escalate into clinical crises that overwhelmed services cannot absorb.

Reaching young people emerged as the third priority. Schools were identified as the key platform, and for good reason: they offer consistent access to large numbers of adolescents within existing structures. Yet participants were careful not to treat schools as the only entry point. Religious groups, madrasah schools, sports teams and centres, community centres, workplaces, digital spaces and peer networks were all noted as potential routes through which support could reach young people who might otherwise be missed. This pluralistic delivery strategy reflects a pragmatic recognition that in a country as diverse as Malaysia, no single institution can carry the entire burden, and that trust is built through the settings where young people already live, learn, pray, play and socialise.

The fourth and fifth priorities concerned the surrounding ecosystem of care. Family-focused programmes were deemed critical to raise awareness of mental health, promote improved dialogue between parents and children, and address the stigma that still clings to psychological distress in many households. Without parental understanding and acceptance, even well-designed school programmes risk collapsing at the doorstep of the family. Integration into existing systems was judged equally essential: this means embedding mental health literacy into school curricula and strengthening delivery systems, including through the training of lay mental health providers who can extend the reach of the formal workforce. Sustainability and scale, participants argued, depend not on creating parallel structures but on weaving mental health into the systems that already function every day.

Advancing these priorities, the workshop concluded, requires genuine multi-sectoral collaboration, particularly across government ministries whose remits intersect in the lives of young people. The Kuala Lumpur meeting itself represented an important first step in that process, placing the Ministries of Health, Education and Digital in the same room as NGOs, United Nations agencies, academics, clinicians and the private sector, all of whom bring complementary expertise spanning Malaysian and international experience. Building on existing initiatives through partnership, rather than duplicating them, was highlighted as a guiding principle. As a critical next step, participants proposed establishing a multi-stakeholder, multi-sectoral Community of Practice to facilitate knowledge and resource sharing, coordinate new initiatives and advocate for greater attention to youth mental health in Malaysia.

The vision behind the proposed Community of Practice is deliberately participatory. It aims to co-create, together with young people, parents and those with lived experience of mental ill-health, a tailored approach to supporting youth mental health in Malaysia, one that ensures cultural and religious relevance and can be embedded within existing structures and systems. Crucially, the ambition does not stop at the border. The Community of Practice is also intended to support regional learning and collaboration, creating opportunities to adapt and scale the approach across Southeast Asia, where many countries face similar demographic pressures, digital transitions and workforce constraints. If the doubling of mental health difficulties among Malaysian children in four short years is a warning, the response taking shape in Kuala Lumpur suggests that regional solidarity, shared evidence and youth partnership may yet turn a gathering crisis into a manageable public health challenge. The cost of inaction, researchers warn, will be measured in a generation’s wellbeing; the opportunity is to act now, with the evidence and the coalition finally in place.

The review, published in Acta Parasitologica by medical entomologist Ian F. Burgess of the Medical Entomology Centre at Insect Research & Development Limited in Cambridge, United Kingdom, revisited and re-evaluated all of the literature linking COVID-19 with head lice. Its conclusions are deliberately contrarian. Despite the increased opportunity for households to eliminate infestations during periods of isolation, some families with no outside contacts reported persistent head louse infestations throughout lockdowns. More strikingly, the review suggests that most reported changes in head louse prevalence were relatively short lived, or in some cases entirely illusory, and that in low- and middle-income countries lockdowns produced little or no measurable difference in prevalence at all.

To understand why the pandemic’s effect on lice was so much weaker than expected, it helps to consider the biology and epidemiology of the parasite itself. The head louse, Pediculus humanus capitis, is an obligate ectoparasite that spends its entire life on the human scalp, cementing eggs to hair shafts and feeding several times a day. Transmission occurs almost exclusively through direct head-to-head contact, which is why children of primary school age, who play and sit closely together, bear the greatest burden of infestation worldwide. Unlike airborne pathogens, lice cannot spread through casual proximity in a classroom; they need sustained contact, typically minutes of touching heads. That makes them exquisitely sensitive to changes in social behaviour, but also means that the household, not the school, can serve as a reservoir that keeps infestations alive even when external contacts are severed.

This reservoir effect is central to Burgess’s revised interpretation. Previous work by the same author had already suggested that some families act as persistent reservoirs of head lice within communities, maintaining infestations across generations of the parasite and repeatedly reintroducing them to schools after treatment campaigns. During the pandemic, the paradoxical reports from households with no outside contacts that continued to experience infestations fit this pattern. If lice were already established within a household, lockdown provided no escape: family members continued to share beds, sofas and close contact, allowing transmission to continue unabated. In such households, the pandemic may even have prolonged infestations, because access to treatment products, professional services and school-based screening was disrupted.

The evidence for a pandemic-driven decline in lice came from several distinct types of data, each with its own weaknesses. Sales figures for pediculicidal treatments fell in several countries beyond the longer-term decline in product sales that had been observed for years before the pandemic, a trend driven largely by widespread insecticide resistance and the shift toward physical methods such as wet combing and silicone-based products. In France, a population-based study reported changes in the dynamics of head lice and scabies infestations during the pandemic, while researchers in Israel compared infestation rates before and during the epidemic and found reductions in some settings. In Buenos Aires, a survey of pediculosis during lockdown documented a decrease in infestation among children. Meanwhile, studies from Poland examined prevalence among children attending schools and kindergartens, and pharmacy sales data from Portugal and Poland were analysed for pandemic-era shifts in consumption of self-care products for pediculosis capitis.

Burgess’s re-evaluation questions how much of this apparent decline was real and how much was artefact. Some of the reported reductions were transient, rebounding as schools reopened and children resumed normal social lives. Others may have reflected changes in diagnosis and reporting rather than genuine changes in prevalence. During lockdowns, routine school screening programmes were suspended, parents had less access to professional diagnosis, and cases that would normally have been detected went unrecorded. Internet search data, which some researchers used as a proxy for infestation activity, capture public interest rather than true prevalence, and searches for head lice in the United Kingdom after the pandemic showed patterns that are difficult to interpret as straightforward measures of infestation. Overdiagnosis and mismanagement of head louse infestations were already well documented problems before the pandemic, with many nits, empty egg cases, mistaken for active infestations, so any decline in consultations could partly reflect reduced opportunities for misdiagnosis rather than fewer live lice.

The geographic pattern of the findings is particularly revealing. In low- and middle-income countries, where head louse prevalence among primary school children is often high and where lockdowns were shorter, less strictly enforced, or economically impossible to sustain, there was little or no difference in prevalence as a result of lockdowns. A systematic review and meta-analysis of prevalence and associated factors among primary school children in these countries documented persistently high infestation rates, and regional studies from places such as southern Iran found no dramatic pandemic-era interruption of pediculosis. In wealthier Western countries, by contrast, where prolonged school closures, furlough schemes and strict social distancing were more feasible, some communities did experience genuine, if temporary, reductions. The longest school closures of the pandemic, documented in global monitoring by UNESCO and Statista, lasted many months, and UNICEF estimated that at least one in seven children and young people lived under stay-at-home policies for most of a year, restrictions that would plausibly have curtailed head-to-head contact.

Yet even in Western settings, the recovery of louse prevalence has been slower than expected, and this is where the review offers its most intriguing conclusion. Some aspects of the social distancing imposed during the pandemic appear to have had lasting effects on children’s social interactions, particularly in Western countries, with a commensurate slower recovery of head louse prevalence in some communities. Long-term surveillance in Cambridgeshire, United Kingdom, published in 2023, documented precisely this pattern: a pandemic-era decline followed by an unusually gradual return toward pre-pandemic levels. Possible explanations include lingering changes in children’s behaviour, such as reduced physical closeness, greater spacing in classrooms, altered patterns of group play, and perhaps heightened parental awareness and treatment following the pandemic experience. Broader research on children’s mental health and socio-emotional development during the pandemic has documented significant disruptions to peer interaction, and it is biologically plausible that these behavioural shifts would be mirrored in the transmission dynamics of a parasite that depends entirely on close contact.

The review also situates head lice within the wider picture of how the pandemic affected contact-transmitted conditions, and here the contrast is instructive. Scabies, another ectoparasitic infestation spread by close contact, showed a more complicated trajectory: some studies reported decreases in scabies and lice cases among paediatric and adult populations during COVID-19, while others documented explosions in scabies cases, particularly where overcrowded households and delayed access to care compounded transmission. Hand, foot, and mouth disease incidence in mainland China fell sharply under pandemic interventions, demonstrating that non-pharmaceutical measures can strongly suppress contact-transmitted infections when they interrupt the right transmission routes. Head lice, by contrast, proved remarkably resilient, because their transmission network is anchored in the household and because the parasite’s long-lived eggs can sustain an infestation through periods when adult lice would otherwise be vulnerable.

For public health practice, the revised view carries practical implications. First, the pandemic did not eliminate head lice from any community, and clinicians and parents should not assume that a decline in reported cases reflects a decline in true prevalence. Second, the persistence of infestations in isolated households underscores the importance of treating all affected household members simultaneously and of adequate diagnosis, ideally with a detection comb rather than visual inspection alone, since combing is demonstrably more sensitive than simple examination. Third, the slow recovery of prevalence in some Western communities offers a natural experiment in how behavioural change can suppress transmission, but it also cautions against overinterpreting short-term surveillance data. Finally, the divergent outcomes between high-income and low- and middle-income settings highlight the role of socioeconomic factors in pediculosis, a relationship documented in schoolchildren decades before the pandemic. As children’s social lives continue to normalise, head louse prevalence appears to be climbing back, at its own pace, toward the levels that have made it one of the most common parasitic conditions of childhood worldwide.
