The Road Less Traveled: Genomic Epidemiology Capacity in State Public Health Programs

a road not traveled much with sequencing



In 2017, the Council of State and Territorial Epidemiologists (CSTE) published its latest Epidemiology Capacity Assessment of state health departments’ workforce size and resources. The assessment inquired about the number of current and optimal epidemiologist positions; sources of epidemiology activity and funding; and states’ self-perceived capacity to lead epidemiology activities, provide expertise, and manage resources for the four Essential Public Health Services most closely associated with the field of epidemiology.
According to the assessment, state health departments employed 3369 epidemiologists. Infectious diseases accounted for a majority (55%) of the epidemiology positions, followed by maternal and child health (10%) and chronic diseases (9%). Genomics accounted for only 4.4 full time employee (FTE) positions currently filled or 0.1% of the total number of FTEs. Overall, state epidemiologists assessed their state epidemiology capacity in genomics as none to minimal (figure).

It is time for public health to begin strategic discussions on how to enhance genomics in state epidemiology programs

In 1998, CDC sponsored a CSTE state assessment that focused on human genomics and disease prevention. The study found that ongoing state public health genetic activities fall under the assurance function (82%), followed by assessment (17%), and policy development (2%), highlighting the need for enhanced epidemiology capacity in genomics. In 2001, our office at CDC defined and mapped public health activities in human genomics in relation to the ten essential public health services. We also defined and published a set of genomic competencies for the state public health workforce, including public health epidemiologists.
With rapid progress in genomics and precision medicine, public health capacity in genomic epidemiology is likely to be increasingly important in several areas.
Since 2014, CDC has begun to enhance state laboratory training in pathogen genomics, including both basic and advanced training for public health microbiologists. In addition, CDC conducted a one-day training for state epidemiologists at the 2016 CSTE conference on the use whole genome sequencing to help solve foodborne and zoonotic disease outbreaks. In addition, there are other specific training efforts embedded in specific infectious disease programs (e.g. tuberculosis, viral hepatitis, HIV).
In summary, genomics is now much closer to clinical and public health applications, highlighting the need to enhance preparedness and capacity in this emerging area. As the science continues to mature, it is time for public health to begin strategic discussions on how to enhance genomics in state epidemiology programs, including competencies, training, resources, and tools. The 10 essential public health services framework provides a blueprint for the integration of genomics throughout public health research, policy and practice.
