The introduction of a medieval public health system exposed the population to roundworm
Medieval health and sanitation efforts involved deliberate interventions; however, some of these measures had the opposite effect, leading to an increased spread of disease in Trondheim.
The introduction of a medieval public health system in Trondheim, Norway, inadvertently exposed the population to roundworm infections. Archaeological findings from two cemeteries, one centrally located and the other on the outskirts, revealed stark differences in the health and diet of the people buried in each site. Those buried in the peripheral cemetery, primarily composed of craft workers, had poorer overall health, higher child mortality rates, and a less varied diet compared to their counterparts living in the central cemetery, who belonged to the city's social elite.
Despite the public authorities implementing hygiene measures, such as cleaner streets and waste management, these efforts did not fully prevent the spread of infectious diseases like leprosy, typhoid fever, and tuberculosis. The shift from private to public responsibility for health and sanitation, driven by societal changes and legal codes, was a dynamic process.
However, even with the implementation of targeted waste disposal measures, roundworms thrived in manure spread throughout the city, infecting nearly the entire population due to the belief that foul smells caused disease.
