The Emory COVID-19 Response Collaborative

The Emory COVID-19 Response Collaborative is an initiative led by the Emory Rollins School of Public Health in collaboration with the Georgia Department of Public Health (GDPH). Its mission is to provide academic support to state and local health department partners during the COVID-19 crisis. One of its seminal programs is the Rollins Epidemiology Fellows Program, a 2-year fellowship designed to attract, place and support early-career epidemiologists across Georgia’s 18 health districts and GDPH. With assistance from ECRC leadership and the Fulton County Board of Health, Applied Epi designed this tailored training session to build the fellows’ analytic capabilities in R through examples tailored to their applied needs in preparing jurisdictional COVID-19 outbreak reports and maps.
