We understand from the passage that such diseases as dysentery and cholera are common in many parts of the tropics ----.
Basic sanitary facilities are absent in many parts
of the tropics, particularly in rural areas, and this
state of affairs is responsible for the prevalence of
preventable diseases such as hookworm
infection, dysentery and cholera. The solution lies
in the provision of toilet facilities which are
suitable for the local conditions, and the villagers
must 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
the risks of infection involved in the old practices
of direct application.
