An epidemiological approach to the analysis of cribra orbitalia as an indicator of health status and mortality in medieval and post‐medieval London under a model of parasitic infection

These results suggest increased mortality risk for those with lesions indicative of anemia (CO), and selective mortality of younger individuals during the medieval period. Despite sex-specific nutritional and occupational hazards, and status-based access to resources, the prevalence of CO was similar across sex and status, which suggests living with parasitic infection that caused anemia was an everyday reality for medieval and post-medieval Londoners.
