Which of the following is not one of the core functions of public health?

The treatment of diseases is a critical aspect of healthcare but is not considered one of the core functions of public health. The primary focus of public health is on the prevention of disease and the promotion of health at the community and population levels.

Assessment involves collecting and analyzing data to understand health issues and needs within a population. Policy development refers to creating policies that support health improvements and address public health problems effectively. Assurance encompasses ensuring that necessary health services are available and accessible to the population, maintaining a healthy environment, and evaluating the effectiveness of programs.

In contrast, treatment of diseases typically falls within the realm of clinical healthcare rather than public health, which aims to prevent diseases and promote well-being among populations rather than treating individuals after they become ill.
