A decade after Zika and Ebola, an open-access public health journal reaches its 10th year
This issue of The Lancet Public Health marks the journal’s 10th anniversary, and the milestone is inseparable from the circumstances that prompted its creation. In 2016, after two Public Health Emergencies of International Concern—Zika and Ebola virus—had exposed how rapidly threats can move across borders, the Lancet team launched an open-access journal devoted to public health. The aim was direct: make research findings freely available so they could reach the people who shape practice and policy without delay or paywall friction.
That founding logic still resonates. Public health decisions rarely wait for perfect certainty, and they are often made in settings where speed, access, and interpretability matter as much as statistical precision. When a new threat emerges, whether infectious, environmental, or commercial in origin, the distance between evidence and action can decide how quickly systems respond. Open access does not solve every problem in public health, but it removes one barrier between research and the communities that need it.
The anniversary also reflects a broader shift in what public health journals are expected to do. Ten years ago, the field was already grappling with infectious disease emergencies, but the intervening decade has made clear that outbreaks are only one part of the burden. Environmental exposures, commercial pressures, structural inequities, and social conditions continue to shape who gets sick, who gets care, and who is protected by policy. A journal built around public health has had to track all of it.
From acute outbreaks to persistent structural threats
The journal’s remit has extended beyond the emergencies that inspired its launch. Over the past decade, it has sought to address the most urgent issues in public health and to respond to new and emerging predicaments, including the environmental and commercial determinants of health. Those are not abstract categories. They are the mechanisms through which health is distributed unevenly long before a clinician sees a patient or a surveillance system counts a case.
Environmental determinants shape exposure at the population level: air quality, heat, housing, and the built environment can all push risk upward in predictable ways. Commercial determinants operate through pricing, marketing, product access, and political influence. Together, these forces influence diet, tobacco use, alcohol exposure, injury risk, and chronic disease trajectories. A public health journal that follows only biomedical endpoints would miss much of the machinery driving those outcomes.
The article’s anniversary framing places health equity at the center of that machinery. Under-recognised determinants are often the ones that do the most damage because they remain invisible in routine clinical encounter data. Inequity can be baked into where people live, work, and age; into whether risk is measured at all; and into whether interventions arrive early enough to matter. Research that names those drivers gives policy a better chance of targeting the causes rather than repeatedly treating the consequences.
The launch of an open-access platform in public health also carries a practical implication for frontline decision makers. Research with immediate relevance to surveillance, prevention, and community intervention cannot sit behind barriers if it is supposed to inform government action, NGO programming, or local health system planning. Free availability expands the audience beyond academic departments and specialty centers. It places the evidence closer to those who must translate it into action.
Why free access still matters in public health practice
Open access is often discussed as an abstract publishing principle, but in public health it has a concrete operational meaning. A field built on population protection depends on broad dissemination, shared interpretation, and rapid uptake. If findings on an outbreak, environmental risk, or inequitable access are difficult to retrieve, their practical value diminishes. The gap between publication and implementation widens, and the populations facing the greatest risk are usually the ones that pay the price.
This is especially important when evidence speaks to systems-level reform. Public health interventions are rarely confined to a single prescription or procedure. They may involve surveillance, legislation, regulation, school-based programs, workplace protections, transportation planning, food policy, or changes in commercial practice. Each of those domains depends on evidence that can be read by policy makers, public agencies, and advocates as well as researchers.
A journal anniversary can easily become a ceremonial marker. Here, it reads more like a statement of purpose. The past decade has shown that public health cannot be separated from the conditions that produce risk in the first place. Outbreaks made that visible in 2016; the years that followed expanded the lens to climate-related harm, market-driven exposures, and persistent inequity. The editorial framing suggests that the journal’s role remains to document those pressures while making the evidence accessible enough to influence action.
The choice to found the journal after Zika and Ebola also captured a truth that still governs public health communication: evidence matters most when it is available at the moment decisions are being made. Delays in access can blunt surveillance, weaken response coordination, and slow the adoption of preventive measures. An open-access journal is not a substitute for strong institutions, but it can support them by making the research base easier to reach and harder to ignore.
Ten years on, the central public health problem remains unequal exposure
The most durable theme in the anniversary note is not simply longevity. It is the recognition that public health work must keep pace with the changing sources of harm. Infectious threats will continue to arise, but so will slower-moving hazards that are no less consequential because they unfold over years rather than days. Air pollution, commercial influence, and social disadvantage may lack the urgency of an epidemic headline, yet they shape far more of the population burden.
That broader frame is what gives the journal’s first decade its significance. Its mission has been to address urgent issues, document emerging threats, and make under-recognised determinants of health visible to a wider audience. The editorial anniversary does not claim that this work is finished. It points instead to the continuing need for accessible evidence that can reach public health practitioners, policy makers, and communities with enough speed to matter.
For a journal born in the wake of two international health emergencies, the next decade will likely depend on the same principle that shaped its first: public health evidence has value only when it can travel. Open access, in that sense, is not a publishing feature. It is part of the infrastructure of response, prevention, and equity.
