    Proximity to water sources, not just access, impacts trachoma risk. Improving hygiene perceptions alongside water access is crucial for reducing disease prevalence.

    Area of Science:

    • Public Health
    • Epidemiology
    • Environmental Health

    Background:

    • Trachoma remains a significant public health concern, particularly in resource-limited settings.
    • Water access and hygiene practices are widely considered critical factors in trachoma prevention.

    Purpose of the Study:

    • To investigate the relationship between water access variables and inflammatory trachoma risk in Tanzania.
    • To assess the association between water variables and facial cleanliness in children as a proxy for hygiene.

    Main Methods:

    • Epidemiological survey conducted in 20 villages in the United Republic of Tanzania.
    • Data collected on village water pump presence, distance to water source, and household water quantity.
    • Assessed inflammatory trachoma prevalence and children's facial cleanliness.

    Main Results:

    • No association found between village water supply presence and trachoma prevalence.
    • Increased risk of trachoma correlated with greater distance to water sources.
    • Children living further from water sources were more likely to have unclean faces.

    Conclusions:

    • Distance to water, reflecting its perceived value and prioritization for hygiene, is a key factor in trachoma risk.
    • Improving water access alone may not suffice; changing perceptions of water utilization for hygiene is essential.
