Molecular Epidemiology and Genomic Approaches

Molecular epidemiology combines molecular biology techniques with epidemiological methods to investigate the genetic and environmental factors that contribute to disease occurrence. By examining the genetic variations associated with diseases, researchers can identify biomarkers, pathways, and susceptibility factors that may influence disease development. Genomic approaches, such as genome-wide association studies (GWAS) and next-generation sequencing, have revolutionized the field by enabling the simultaneous analysis of thousands of genetic variants and their relation to complex diseases. Through the integration of genetic data with traditional epidemiological methods, molecular epidemiology enhances our understanding of disease etiology and supports personalized medicine approaches. Moreover, molecular epidemiology plays a crucial role in infectious disease surveillance, outbreak investigations, and identifying genetic markers of drug resistance. The interdisciplinary nature of molecular epidemiology bridges the gap between genomics and population health, offering insights into disease prevention, diagnosis, and treatment strategies.
