Long COVID disability burden in US adults.
Bonuck, Karen, Gao, Qi, Congdon, Seth et al. · Communications medicine · 2026 · DOI
Quick Summary
This study measured how much disability Long COVID causes in American adults and compared it to other diseases like Alzheimer's and asthma. The researchers found that Long COVID causes as much disability as these well-known conditions, yet the U.S. government funds research on Long COVID with only 14% of the money it should based on that disability burden. The study also found that diseases affecting mostly women receive about 5 times less research funding per unit of disability than diseases affecting mostly men.
Why It Matters
ME/CFS and Long COVID share overlapping pathophysiology and disability burden yet remain severely underfunded relative to comparable conditions. This study demonstrates systematic underfunding of female-predominant conditions and provides quantitative evidence that research funding decisions do not reflect actual disease disability burden, directly advocating for resource reallocation toward ME/CFS and similar neglected conditions affecting primarily women.
Observed Findings
Long COVID disability burden (YLDs) approximates that of Alzheimer's disease and asthma in US adults.
Long COVID received $106 million in NIH funding (FY2022-2024) versus the $739.8 million proportionate to its disability burden (14% of adequate funding).
ME/CFS is the most underfunded condition, receiving less than 1% of its YLD-proportionate funding.
Funding per YLD was 5.2-fold higher for male-predominant ($7.0M/YLD) versus female-predominant conditions ($1.3M/YLD, p=0.007).
YLDs alone explained only 6.5% of variance in NIH funding allocations across conditions.
Inferred Conclusions
NIH research funding is poorly aligned with disease disability burden, particularly for conditions affecting predominantly female populations.
Sex-based disparities in research funding reflect systematic undervaluation of female-predominant diseases independent of disability impact.
ME/CFS and Long COVID represent critical gaps in research investment relative to their substantial public health burden.
Currently unmeasured factors beyond disability burden drive NIH funding allocation decisions, warranting policy reform to better align resources with patient disability and unmet medical need.
Remaining Questions
What This Study Does Not Prove
This study does not prove that increased funding would improve Long COVID or ME/CFS outcomes, nor does it establish causation between funding levels and health disparities. It also does not account for other factors influencing funding decisions (e.g., patent potential, advocacy visibility, research feasibility), and cross-sectional design precludes temporal relationships. The study cannot explain why YLDs account for only 6.5% of funding variance.

About the PEM badge: “PEM required” means post-exertional malaise was an explicit required diagnostic criterion for participant inclusion in this study — not that PEM was studied, observed, or discussed. Studies using criteria that do not require PEM (e.g. Fukuda, Oxford) are tagged “PEM not required”. How the atlas works →
