National Public Health Week begins today—and we’re kicking it off with a look at public health in action.

This is just a fraction of the work that keeps Californians healthy every single day:

- Seatbelts and car seats saving lives

- Vaccines preventing disease

- Water quality testing that protects communities

- Inspectors in the field

- Researchers analyzing data

- Educators sharing resources

- And so much more

To those working to improve the health of Californians, we thank you for protecting us all—every day of the year.
