…Researchers say economic gaps, not labs or stockpiles, drive pandemic deaths
By Danjuma AMODU
A major international study has challenged decades of global health policy, concluding that economic inequality — not the strength of a country’s laboratories, emergency plans or healthcare infrastructure — is the strongest predictor of how severely nations suffer during pandemics.
The findings, published in the New England Journal of Medicine by a team led by Nobel Prize-winning economist Joseph Stiglitz and other leading global health experts, argue that governments must fundamentally rethink pandemic preparedness by placing inequality at the centre of health security strategies.
The research, conducted by the Global Council on Inequality, AIDS and Pandemics, found that countries traditionally ranked among the world’s best prepared for pandemics, including the United States and the United Kingdom, recorded some of the highest COVID-19 infection and death rates despite their advanced medical systems.
By contrast, countries with lower conventional preparedness rankings but relatively lower levels of inequality, such as Vietnam and Ethiopia, performed significantly better in containing the pandemic.
The researchers found no meaningful link between traditional pandemic preparedness indicators and actual outcomes during COVID-19 or the AIDS pandemic. Instead, they identified income inequality as the clearest predictor of deaths and infections.
According to the analysis, every one-point increase in a country’s Gini coefficient — the standard measure of income inequality — was associated with approximately 12.5 additional COVID-19 deaths per 100,000 people. The same relationship was observed for AIDS-related deaths and new HIV infections, even after accounting for poverty levels and existing health infrastructure.
The report argues that inequality weakens public health responses by limiting people’s ability to comply with health measures, reducing trust in public institutions and creating unequal access to healthcare services.
“High economic inequality can leave even wealthy, well-equipped nations dangerously exposed.”
— Joseph Stiglitz, Nobel Laureate in Economics
It warns that over 90 per cent of the world’s population now lives in countries experiencing high levels of income inequality — the highest since the Industrial Revolution — making the global community increasingly vulnerable to future pandemics.
To reverse the trend, the researchers proposed an “Inequality-Informed Pandemic Preparedness and Response” framework that shifts attention beyond hospitals and laboratories to broader economic and social policies.
Among their recommendations are expanding paid sick leave, unemployment benefits and cash transfers during health emergencies; integrating finance, labour and education ministries into pandemic planning; reforming global financial systems through emergency debt relief and automatic international funding; and promoting open licensing of publicly funded medical research alongside expanded regional production of vaccines and medicines.
Joseph Stiglitz, Co-Chair of the Global Council, said the findings expose fundamental weaknesses in the world’s current approach to pandemic preparedness.
“For decades the world judged how ready a country is for a pandemic by counting its laboratories, stockpiles and response plans. This research shows that this is not enough,” he said.
UNAIDS Executive Director Winnie Byanyima described inequality as the underlying driver of pandemics, saying governments now have clear evidence on where action is needed.
“The research proves that inequality is the ground in which pandemics take root. By tackling inequality, we can end AIDS as a public health threat and make the world safer from future pandemics,” she said.
The publication comes ahead of discussions at the AIDS 2026 Conference in Rio de Janeiro, where global leaders will examine the findings and their implications for future international health policy.
The Global Council on Inequality, AIDS and Pandemics was convened by UNAIDS to examine how social and economic inequality shapes responses to infectious disease outbreaks. The Council’s latest study compares countries’ responses to both COVID-19 and HIV/AIDS and concludes that conventional preparedness indices — which primarily assess technical capacity such as surveillance systems, laboratories and emergency response mechanisms — fail to predict real-world performance.
The findings come as governments worldwide reassess pandemic preparedness following COVID-19, which claimed millions of lives globally, while HIV/AIDS has killed more than 44 million people since the early 1980s. The researchers argue that reducing inequality should now be regarded as a core pillar of global health security rather than simply a social policy objective.
