This science is divided into fields like biostatistics, environment, social behaviour, epidemiology, occupation and epidemiology.
This public service has two distinct characteristics. The first characteristic deals with preventive rather than curative aspects.
The second characteristic deals with population-level, rather than individual-level of issues.
Now the focus of this social service is to prevent rather than treat a disease through surveillance, follow up and monitoring of cases and the promotion of cleanliness.
In addition, in most cases treating a disease can be vital and important to preventing its spread to others, such as during an outbreak of infectious epidemic.
It is also equally important to protect a community from contaminated food or water sources.
Vaccination programs and distribution of medical face masks are examples of public health measures.
