title: Contributions to the Improvement of Living Conditions among Neglected Populations with Trachoma.
abstract: OBJECTIVE
  Trachoma (Chlamydia-triggered blinding infection) provoked irreversible visual impairment in about 8 million people in 2011, and the prevalence among children with dirty faces is more than three fold that among children with clean faces. In 250 villages with a high prevalence of trachoma (Kolofata district, Far North Region, Cameroon), the lack of water for facial cleanliness was reported during trachoma awareness campaigns. The objective of this study was to determine if the lack of water was linked with the absence of means to dig wells.
  
  
  METHODS
  Wells, waterholes, motorcycles, irrigation pumps, electricity, goats and oxen, cell phones and distance from waterholes were recorded in January 2011 in 50 randomized villages of Kolofata's district.
  
  
  RESULTS
  The number of villages with <25 goats and <5 oxen was 0 and the number of adults owning <1 goat was 0. The cost of a pail of water was 0.01 USD. Motorcycles, cell phones and televisions have been reported in more than 66% of villages. The cost for the construction of lined shaft wells ranged between 15-35 goats and 0.5-3 oxen; the cost for drinking water wells ranged between 50-200 goats and 3-30 oxen.
  
  
  CONCLUSIONS
  No link between the means for digging wells at the village level and access to water was found. Social solidarity, which refers to a social debt owed by each person to his/her group, should be added to training guides to gauge its ability to release people from the dead end of having to wait for external assistance to gain access to water.
