Molecular epidemiology describes a process of identifying the genetic basis of disease, including variants within hosts and pathogens that influence infection, transmission, and prevention. Molecular epidemiologists typically focus on determining sources of infection, tracking transmission routes, and identifying genes responsible for virulence and drug resistance, to support hospital infection control and epidemiological investigations.
Next-generation sequencing (NGS) allows highly accurate, hypothesis-free analysis of multiple isolates for detection, replacing multiple tests to identify organisms and examine resistance and virulence. In contrast, traditional methods of pathogen identification and characterization are often guided by serial hypotheses and are optimized for only a limited number of organisms.
In combination with extensive epidemiological findings, the portable iSeq 100 System enabled local scientists to analyze transmission patterns and trace the outbreak's origin.Read Article

A key advantage of NGS is that researchers can generate genome sequence data capable of identifying a range of organisms (bacteria, viruses, and parasites). Examining variations across genomes supports cross-sectional studies for better understanding of mechanisms that lead to infection and spread, as well as phylogenetic analysis to determine relatedness among organisms.
High-resolution pathogen typing using whole-genome sequencing data can differentiate organisms that many older methods cannot distinguish.
Microbial whole-genome sequencing can help epidemiologists overcome traditional challenges of tracking disease origins and investigating outbreaks.
