Health Equity Analysis

SDOH factors, access disparities, and structural inequities in invisible illness care

Worst Funding Ratio: 3,400:1
Rural Claims Growth: 357%
Gender Gap (POTS): 80%
Longest Diagnosis Delay: 7 yrs

Diagnostic Delay by Condition

Average months from symptom onset to diagnosis

Source: CDC clinical guidance, IDSA, peer-reviewed literature. Alpha-gal Syndrome: 84 months, Fibromyalgia: 60 months, Lyme Disease: 52.8 months, ME/CFS and POTS: 48 months each, Long COVID: 6 months. Delays represent averages; many patients wait significantly longer.

NIH Funding vs Disease Burden

ME/CFS has the most extreme burden-to-funding ratio of any U.S. disease

Critical disparity: ME/CFS costs the U.S. $149B–$362B/year — comparable to Alzheimer’s ($340B/year) — yet receives only $15M in annual NIH funding. This 3,400:1 burden-to-funding ratio is the most extreme of any U.S. disease.

Rural vs Urban Disparity

Lyme disease claims growth by setting (FAIR Health 2007–2021)

Rural Lyme claims grew 357% vs 185% urban — nearly 2x faster. Yet rural areas have fewer infectious disease specialists per capita.

Gender Disparities

Women bear a disproportionate burden across invisible illnesses

Female patient percentage by condition: POTS 80%, Fibromyalgia 67%, Long COVID 63%, Lyme 52%. Despite higher prevalence in women, these conditions are historically under-researched and often dismissed as psychosomatic.

Sources: CDC, NIH RECOVER, peer-reviewed literature.

Equity Gaps

Structural barriers that perpetuate invisible illness disparities

Data sources: U.S. Census Bureau Household Pulse Survey, CDC MMWR, CDC NNDSS, NIH Reporter, FAIR Health (2007–2021), CMS Chronic Conditions PUF, AHRQ MEPS, Adrion et al. 2015 (Johns Hopkins), Hook et al. 2022 (CDC/EID), Harvard/Cutler 2022, Brookings 2023.
