Definition and Scope of Environmental Health
Health problem is a very complex issue, which is interrelated with other issues beyond the health.
Similarly, solving public health problems, not only in terms of their own health, but it must be seen from all aspects that have an effect on the problem of "healthy-sick" or the health.
Many factors affect health, both the individual and public health. For this case, Hendrik L. Blum described briefly. The four factors are heredity, environment, behavior and health services, in addition to direct effect on health, they also affect to each other. Health status will be achieved optimally when those factors have optimal conditions. One of the factors is interrupted or not in optimal condition, then the health status will be shifted towards suboptimal.
Environmental health is essentially a condition or state of optimum environment that has positive influence on the realization of optimum health status.
The scope of environmental health include: housing, disposal of human waste (feces), water supply, waste disposal, sewage or wastewater, livestock houses (cages and so on).
Environmental health effort is an attempt to improve or optimize the human environment in order to be a good medium for the realization of optimum health for people who live in it.
The effort to improve or enhance the environmental condition is from time to time, and from one community to another community that varied and stratified, from the most simple (primitive) to the most modern.
