Ancient sewers expose a hidden health crisis in Roman Britain

Sediments from a Roman latrine at Vindolanda show soldiers were infected with multiple intestinal parasites, including roundworm, whipworm, and Giardia - the first time Giardia has been identified in Roman Britain. These parasites spread through contaminated food and water, causing diarrhea, weakness, and long-term illness. Even with sewers and communal toilets, infections passed easily between soldiers. The discovery highlights how harsh and unhealthy life could be on Romes northern frontier.
