What is public health?

Public health promotes and protects the health of all people and their communities. This science-based, evidence-backed field strives to give everyone a safe place to live, learn, work and play.

Why is public health important?


Public health improves our quality of life, helps children thrive, reduces human suffering and saves money. Every day, the public health field is working – often behind the scenes – to prevent hazards and keep people healthy.


Public health is responsible for:

  • Tracking disease outbreaks and vaccinating communities to avoid the spread of disease.
  • Setting safety standards to protect workers.
  • Developing school nutrition programs to ensure kids have access to healthy food.
  • Advocating for laws to keep people safe, including smoke-free indoor air and seatbelts.
  • Working to prevent gun violence.
  • Addressing the impact of climate change on our health.
  • Declaring racism as a public health crisis.
