Gun violence is a major public health issue causing significant death, injuries and years of life lost. Gun violence and gun safety are complex public health problems and challenges that can benefit from a systems-thinking approach. This course will focus on how local health departments can take action to address gun violence in their communities. The course describes two examples of how different counties in the state are applying the public health approach to gun violence in their communities and using systems thinking to help define the problem and identify risk factors and areas to intervene.
