Public Health

Public health is the science of protecting and advancing the health of people and communities throughout the state, the nation, and the world by the promotion of healthy lifestyles, detection and control of infectious diseases, and research for disease and injury prevention.

While a doctor may diagnose and treat people who are sick, public health professionals try to prevent problems from happening or reoccurring by recommending policies, conducting research, administering services, and implementing educational programs that encourage healthy behaviors to prevent chronic diseases and improve mental health and wellness.

There are many facets to public health which can include setting safety standards to reduce death and disability by protecting people from unintentional injuries, enforcement of regulatory controls to prevent air and land pollution, developing nutrition programs to ensure that children have access to healthy food, educating people about the risks of infectious diseases, social violence and substance abuse, facilitating access to prenatal education, and much more.
