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. For example, 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.
