A consensus or society position rather than new primary data.
This is a narrative review summarizing the state of evidence for incorporating human genetics into community medicine and public health, spanning genetic epidemiology, risk prediction, screening, infectious disease genomics, pharmacogenomics, and non-communicable disease prevention. The review frames precision public health as an emerging integrative discipline and identifies key implementation barriers including ancestry bias, ethical considerations, and health system readiness, with examples from Indian national genomic initiatives.
Narrative review. General population across multiple disease domains; specific emphasis on the Indian population and context..
Advances in genomic technologies and falling sequencing costs have enabled integration of genetic insights into public health over the past two decades Polygenic risk scores, pathogen genome sequencing, and pharmacogenomic testing are identified as tools with potential to enhance early detection, targeted prevention, and rational therapeutics Population-specific genomic approaches are necessary in countries with distinct genetic diversity from endogamy and founder effects, exemplified by India
Specific efficacy or effectiveness data for individual tools (e.g., polygenic risk scores, pharmacogenomic testing) not provided in source text Polygenic risk scores, pathogen genome sequencing, and pharmacogenomic testing are identified as tools with potential to enhance early detection, targeted prevention, and rational therapeutics
This review provides a framework for understanding how genomic tools can be operationalized in public health and community medicine settings. Clinicians and public health professionals should be aware of both the potential of precision approaches and significant implementation barriers, particularly regarding ancestry bias and health equity.
A narrative review synthesizing evidence and expert perspectives on integrating genomics into public health practice, with discussion of implementation frameworks rather than reporting new empirical results.

Graded across the dimensions that decide whether you should act, each from what the source actually supports. There is no single score, and where a dimension was not assessed it says so.
What is missing. This record has no reported figures. That is a gap in the analysis, not a judgement about the study.
Historically, human genetics and community medicine have evolved as separate disciplines. The domain of genetics has been on molecular mechanisms of disease and community medicine has traditionally been on prevention at the population level and health systems. Over the last two decades, advances in genomic technologies, falling sequencing costs and the expansion of large-scale biobanks have made it possible to integrate genetic insights into public health. This convergence has led to the development of precision public health, which seeks to improve disease prevention, risk stratification and health interventions at the population level. Moreover, in countries such as India, the distinct genetic diversity resulting from endogamy and founder effects points to the necessity of population-specific genomic approaches within public health frameworks. This review summarizes the existing evidence for the incorporation of human genetics into community medicine in the following areas: genetic epidemiology, population risk prediction, genetic screening across the life course, infectious disease genomics, pharmacogenomics, and genetic determinants of non-communicable diseases. It shows the potential of tools such as polygenic risk scores, pathogen genome sequencing and pharmacogenomic testing to enhance early detection, targeted prevention and rational therapeutics. The review also discusses the Indian context, with examples of national initiatives such as the Genome, India Project and the National Sickle Cell Elimination Mission as examples of translating genomic science to public health practice. Crucially, it addresses implementation challenges such as ancestry bias, ethical considerations, health system readiness, and the need for culturally sensitive community engagement.
