Roman soldiers defending Hadrian’s Wall infected by parasites, study finds

Research found 28% of latrine samples contained parasite eggs, revealing infections likely caused malnutrition and reduced Roman soldiers’ fitness at Vindolanda.

  • Sediment analysis of a nine-metre drain at Vindolanda found evidence of roundworm, whipworm, and Giardia duodenalis, marking the first record of Giardia in Roman Britain, according to researchers from Cambridge and Oxford.
  • Despite impressive water technology, Vindolanda's bathhouse drainage and spring water failed to stop parasites spreading via fecal-oral transmission, and Roman medical practitioners and treatments could not clear infections.
  • Using ELISA and microscopy, researchers tested 50 sediment samples from the nine-metre latrine drain at the third-century bath complex, finding 28% with helminth eggs and one positive for Giardia via biomolecular techniques.
  • The historical record from Vindolanda mentions ten men unfit for duty, supporting Dr Marissa Ledger's view that parasites could cause malnutrition and diarrhoea, while Dr Piers Mitchell said, `Untreated giardiasis can drag on for weeks, causing dramatic fatigue and weight loss.`
  • These results challenge Roman hygiene narratives by showing Vindolanda had fewer parasites than London and York, yet infections persisted, as Dr Andrew Birley says this deepens understanding of hardships nearly 2,000 years ago.
