Human beings themselves are the main reserviour of most diseases that affect them. Transmission of the excreata-related diseases from one host to another follows one of the routes.
Control-
If transmission of diseases blocked at one or more points, excreate-related diseases can be controlled or possibly eradicated. Good sanitation practice can help towards the goal. eg. Water-seal slabs in latrine reduce the breeding sites for mosquotoes, vectors of filariasis. Treatement of excerata prior to its disposal can kill the eggs and cysts of many human parasites like Ascasis, Entamoeba, Schistosoma spp thus preventing contamination of both ground and water. Instead of treating human excreata as a social problem, if ways are devised where it could be used as a natural resources to be conserved and reused under careful control, then many of the associated problems could be corrected. There are three basic methods of using this sources.
