Everything is Public Health
Everything is public health and public health is for everyone.
So many things impact our health. The physical things around you, the social interactions, the policies you may never notice, are all quietly there, protecting our health and well-being in subtle ways everyday. This is the world of public health; a science of understanding the countless forces and designing solutions to help prevent or mitigate harm and improve the health and well-being of the people. Public health saved your life today, and you probably didn't notice.
