Abstract
This roundtable session will involve a hands-on, interactive workshop where participants will be taught how to use three web-based surveillance tools (Public Health Information Management System, Social Determinants of Health Mapper, and South Eastern Integrated Information Portal). The tools apply deprivation and marginalization indices, as well as other environmental and geographic layers, to virtual maps. With the help of these tools, the user will be able to easily track vulnerable populations. The layers available in the tools, and how they apply to specific geographic areas, are important to consider when making public health decisions so as to improve health equity and act on social determinants of health.
