The research arrives at a moment when the political appetite for pandemic restrictions has waned dramatically, even as the risk of novel respiratory pathogens remains undiminished. A novel influenza subtype, another coronavirus with pandemic potential, or an as-yet-uncharacterized virus could emerge with little warning, forcing governments once again to weigh the health benefits of closing schools, workplaces and hospitality venues against the livelihoods those closures threaten. The analysis frames this not as a binary choice between saving lives and saving the economy, but as an optimization problem that can be solved with the right data.

Central to the study’s methodology is the coupling of epidemiological transmission models with macroeconomic loss projections. Rather than treating infections and GDP as separate domains, the researchers simulated how different intervention portfolios would shape both the epidemic curve and the economic trajectory of a hypothetical pandemic. Each scenario specified which sectors or activities would be closed, when the closures would begin relative to the onset of community transmission, how long they would remain in force, and how stringently they would be enforced. The model then propagated these choices through simulated population networks to estimate infections, hospitalizations and deaths, and through economic accounting frameworks to estimate output losses over the course of the pandemic and its aftermath.

The socioeconomic scenarios varied along dimensions that proved critical to the results, including the contact intensity of different sectors, the share of workers able to telecommute, the severity and transmissibility of the pathogen, and the availability of compensating fiscal support. This breadth of scenario design is what distinguishes the analysis from earlier efforts, many of which examined a single country, a single pathogen profile or a narrow set of interventions. By spanning this parameter space, the study seeks findings robust enough to guide policy before the characteristics of a future pandemic are fully known.

Three of the study’s headline conclusions concern timing. First, the model consistently finds that interventions introduced early in the growth phase of an epidemic—before infections, hospitalizations and deaths accumulate—reduce both the health burden and the total economic loss. Early closures can be shorter and less stringent while achieving comparable reductions in peak transmission, which limits the cumulative output foregone. Second, delayed interventions are associated with the worst outcomes in the simulation: by the time hospitals come under pressure, transmission has dispersed widely through the population, forcing longer and broader restrictions to achieve the same epidemiological effect and compounding the economic toll. Third, premature relaxation can be as costly as late implementation, because resurgence triggers a second round of restrictions and prolongs the period of economic uncertainty that suppresses investment and consumption.

The findings on the type of intervention are similarly instructive. Across most scenarios, closures that target high-contact, low-productivity sectors generate better health-to-economic trade-offs than blanket lockdowns of the entire economy. Hospitality, entertainment, large-scale events and other venues where transmission risk per hour of activity is high but value added per worker is comparatively modest emerge as logical first candidates for closure. By contrast, sectors essential to supply chains, health care and food provision are better protected through workplace risk mitigation, such as ventilation improvements, masking, cohorting and testing, than through shutdown. The model’s emphasis on heterogeneous, sector-targeted closures reflects the accumulated evidence from COVID-19 that transmission risk is highly uneven across settings.

Duration emerges as the third critical lever. The analysis suggests that fixed-duration closures specified far in advance perform worse than adaptive strategies in which interventions are scaled and timed according to epidemiological indicators such as the effective reproduction number, hospitalization rates or wastewater surveillance signals. Adaptive frameworks allow policymakers to lift restrictions when transmission is controlled and reimpose them temporarily during resurgence waves, keeping the cumulative economic burden lower than either indefinite restrictions or one-shot closures. The study’s projections imply that well-calibrated adaptive policies can shorten the total duration of disruptive measures while holding infections to a level that a strained but functioning health system can absorb.

Not all of the study’s results are uniform across scenarios. Where the pathogen is assumed to be less transmissible but more lethal, early and stringent measures dominate on both health and economic grounds, because the value of prevented hospitalizations and deaths rises sharply. Where the pathogen is highly transmissible but less severe, the model points toward interventions focused on protecting high-risk populations and critical services rather than economy-wide shutdowns. The availability of remote work also reshapes the calculus: economies with high teleworking capacity sustain lower output losses from workplace measures, whereas economies dependent on in-person services face steeper trade-offs, a finding with clear implications for global equity given that lower-income countries generally have less telework infrastructure and thinner fiscal buffers to cushion affected workers.

The authors are careful to situate these projections within the limits of epidemiological and economic modelling. Prospective scenarios cannot anticipate the pathogen’s actual characteristics, the behavioral responses of populations, or the political constraints under which real governments operate. Compliance drifts, enforcement varies and informal economies absorb damage in ways that national accounts capture imperfectly. The models also abstract from the long-term health and educational consequences of interventions, which the authors note should inform any complete welfare assessment. What the analysis provides is not a prescription but a map: a structured comparison of hundreds of possible policy pathways, each scored on both epidemiological and economic dimensions, that policymakers can consult when the parameters of a real crisis begin to come into focus.

The practical implications are already visible in the evolving policy debate. Several countries have drafted pandemic preparedness plans that embed trigger-based intervention frameworks, and international bodies have called for investment in the surveillance infrastructure—genomic sequencing, wastewater monitoring, syndromic surveillance networks—required to detect transmission surges early enough for adaptive strategies to work. The study’s findings reinforce the argument that such investments are economic as well as public health measures: the faster an emerging outbreak is detected and characterized, the shorter and narrower the closures required to control it. As governments rebuild their preparedness stockpiles and revise playbooks, this analysis suggests that the most valuable asset in the next pandemic may be time, and that every day of early detection buys disproportionate savings in both lives and output. The full modelling details and scenario results are available in the open publication, allowing national and local planners to adapt the framework to their own demographic and economic conditions.

The scale of the underlying problem is considerable. In the United Kingdom, approximately one in 20 women develop post-traumatic stress disorder following childbirth, a condition that can flashbacks, nightmares, avoidance behaviours and severe anxiety to persist for months or years after delivery. Many more women describe their birthing experience as traumatic even when they do not meet full diagnostic criteria, and recent research has shown that postnatal PTSD remains substantially underdiagnosed across the UK, meaning many affected women never receive formal recognition or treatment for their suffering. The new economic analysis adds a powerful financial dimension to this clinical picture, demonstrating that the hidden burden of birth trauma translates directly into increased demand on health services and, by extension, on the public purse, strengthening the case for earlier identification and intervention.

The report was authored by the MAP Alliance research team and represents the first published attempt to estimate some of the economic costs associated with PTSD following childbirth in the UK, with a primary focus on healthcare use among affected women. Its evidence base is unusually robust for this field: the analysis draws on a programme of perinatal mental health research that tracked more than 2,000 women in England and Scotland from pregnancy through to two years after birth, repeatedly assessing their mental health, their use of health services and their occupational outcomes. Crucially, the postnatal assessments captured not only PTSD arising from childbirth itself but also PTSD stemming from other traumatic experiences, allowing the researchers to distinguish between trauma related specifically to the birth and trauma from other sources. The report also incorporates findings from a separate survey conducted by the Birth Trauma Association documenting women’s personal accounts of birth trauma and its effects on their lives.

The key findings are stark. Healthcare and support service costs for women with childbirth-related PTSD were 2.5 times higher than for women without PTSD during the six to twelve months after birth. Even women with low or moderate PTSD symptoms, including those reporting only one or two symptoms, showed increased healthcare service costs compared with women without PTSD, demonstrating that the economic impact of birth trauma begins well below the diagnostic threshold. Employment outcomes were also affected: by twelve months postpartum, only 53 percent of women with PTSD had returned to work, compared with 68 percent of women without symptoms, pointing to longer-term economic and employment consequences that extend far beyond the health service. Although women with PTSD were more likely to be referred to mental health support services, more than half received no referral at all, exposing serious gaps in access to appropriate care. Women whose PTSD stemmed from traumatic birth also had slightly higher healthcare costs than those with PTSD arising from other traumas, suggesting greater healthcare needs in this group.

The findings arrive against the backdrop of mounting concern about maternity safety and accountability. The 2024 APPG Birth Trauma Inquiry, co-chaired by Rosie Duffield MP, highlighted the significant impact of birth trauma on women and families and explicitly called for research evidence on the public health and wider societal costs of postpartum PTSD. That call has now been answered with hard numbers. The wider medico-legal context is equally sobering: maternity-related clinical claims against the NHS in 2024-25 cost £3.5 billion, representing 53 percent of all clinical claims by value received in that year. While the new report deliberately restricted its scope to healthcare use, the researchers acknowledge that substantial additional costs fall outside its estimates, including lost productivity, informal care, family breakdown and the long-term effects on children, meaning the true economic burden is likely to be considerably larger than the figures presented.

Professor Susan Ayers, co-author of the report and Professor of Maternal and Child Health at City St George’s, University of London, emphasised the breadth of harm that PTSD symptoms impose on families in the postpartum period, whether the trauma originates in a difficult birth or in other adverse experiences. She noted that many of these outcomes carry direct cost implications for the public purse, and that the research, which focused specifically on healthcare service use, found that health service costs alone for women with PTSD and their babies are over double those of women without PTSD within the first two years after birth, and possibly beyond. Ayers warned that unless action is taken to address birth trauma and PTSD, the annual cost of health service use by women and their babies will remain high, and argued that preventing traumatic births alongside implementing routine screening and treatment for PTSD would both benefit women and families and begin to bring these costs down.

The report’s publication was greeted with strong language from patient advocates. Dr Kim Thomas, Chief Executive of the Birth Trauma Association, said the study shows for the first time the scale of the financial cost of birth trauma to the NHS. She explained that the charity has long been aware that women affected by traumatic birth need far more care in the months and sometimes years following birth, whether in the form of counselling, physiotherapy or surgery. Describing the finding that traumatised women represent a cost to the NHS two-and-a-half times greater than other women in the postnatal period as a wake-up call to policymakers, Thomas urged the government to commission research into the wider costs to the economy when women are lost to the job market or their families break up as a consequence of birth trauma.

In Parliament, the report’s launch was framed as the culmination of years of campaigning. Rt Hon Rosie Duffield MP, Chair of the APPG on Birth Trauma, described it as a landmark report believed to be the first UK research into the economic cost of birth trauma and postpartum PTSD, building directly on the APPG’s 2024 Birth Trauma Inquiry, which she co-chaired and which highlighted the urgent need for research into the wider economic impact of birth trauma. She noted that the APPG has heard compelling evidence of the significant costs involved, from direct pressures on the NHS to lasting financial consequences for families, and welcomed the fact that Professor Ayers secured funding to undertake the work.

Turning evidence into policy, the researchers set out a clear set of recommendations. They call for routine screening and interventions for PTSD during pregnancy and after childbirth, alongside increased access to specialist perinatal mental health support for women experiencing symptoms. They emphasise that preventing traumatic births in the first place has the potential to save the NHS a substantial amount of money while improving the wellbeing of women and families. Workforce training is also highlighted as essential, to raise awareness of perinatal trauma and PTSD, embed trauma-informed principles of care, and help clinicians identify and support women at risk. Finally, the authors stress that further research is needed to ensure screening tools, treatments and trauma-informed care pathways are effective and evidence based, so that a problem long invisible in economic terms can finally be met with services equal to its scale.
