Public health importance of excreta disposal



The inadequate and insanitary disposal of Infected human faeces leads to the contamination of the ground and of water supply sources. It often attracts certain species of flies to lay their eggs, to breed, to feed on the exposed material, and to carry infection. It also attracts domestic animals and rodents and other vermin which spread the faeces; and it sometimes creates intolerable nuisances.

Poor excrete disposal is often associated with the lack of adequate water supplies and of other sanitation facilities and with a low economic status or the rural population. These conditions, all affect the health and well-being of the people in a community.

When proper disposal systems exist, it is known that the incidence of a large group of diseases is reduced. This group of diseases includes cholera, typhoid and paratyphoid fevers, the dysenteries, infant diarrhoeas, hookworm disease, ascariasis, bilharziasis, and other similar intestinal infections and parasitic infestations. These diseases lay a heavy hand on infants, whose immunity is low and whose vigor is often not great enough to cope with an infection after it becomes established.

Proper practices of excreta disposal car result in increased life expectancy, healthier and strong people more effectively able to cope with their environment, and opportunities for improved local living conditions.
