Fundamental sanitary facilities are non-existent
in many parts of the tropics, particularly in rural
areas, and this state of affairs is responsible for the continuity of preventable diseases such as
hookworm infection, dysentery and cholera. The solution lies in the provision of toilet facilities that
are suitable for the local conditions, and the villagers should be
educated to use them and to
appreciate their value to the community. In view of the need to improve the fertility of the soil, local
authorities are becoming increasingly interested in simple methods of composting village waste, in
this way invigorating the soil with valuable humus without any risks of infection involved in the old
practices of direct application.
