Our Work

Since 2001, CSTE has conducted seven periodic Epidemiology Capacity Assessments (ECAs) to monitor the numerical strength and functional applied epidemiology capacity in state and territorial health departments.

The 2021 ECA was completed by the State and Territorial Epidemiologists from all 50 states, the District of Columbia, and four territories. This report represents the most complete and comprehensive national data on epidemiology workforce needs.

Key Findings

  • Major gaps exist in the applied epidemiology workforce despite recent growth due to surge staffing for the COVID-19 pandemic response.
  • An additional 2,196 epidemiologists are needed to deliver public health services in state and territorial health departments alone based on current operations, which would be a 53% increase in staffing. This does not account for epidemiology work force needs at the local or tribal levels.
  • Since 2017, infectious disease, chronic disease and maternal and child health all experienced a decrease in epidemiologists. The applied epidemiology workforce is concentrated primarily in infectious disease and COVID-19 response.
  • Most salary increases in career-level categories did not surpass the 7.9% inflation rate from 2017 to 2021, and many states struggled to stay competitive because their salaries ranged well below the national average.
  • Departments continue to rely heavily on federal funding for epidemiology activities and personnel.
  • Capacity to monitor and investigate health problems remains high, but evaluation and research capacity lag behind.
  • Similar to 2017, the greatest training priority remains data analytics.

Background of the ECA

In 1995, CSTE spearheaded a national epidemiology workforce assessment effort and compiled a guide to aid states in assessment of their epidemiologic capacity. CSTE followed up this effort in 1997 with an assessment piloted in 10 states and in 2001 with the first ECA. The ECA was the first national assessment of core epidemiology capacity in state and territorial health departments. CSTE administered additional ECAs in 2004, 2006, 2009, 2013 and 2017. CSTE also conducted an epidemiology enumeration assessment in 2010 to determine the epidemiology workforce in both state and local health departments.

Uses of ECA Data

ECA data are paramount in CSTE’s advocacy efforts. Data from ECAs have been shared as Congressional hearing testimony in support of greater targeted funding for capacity development. ECA results help illuminate the status of state epidemiology efforts and assist our member states with targeting improvements in epidemiology capacity within their health departments. Future ECAs will attempt to continue capturing information about workforce capacity.
