DNA sequencing is rewriting our understanding of historic outbreaks, but it can't tell the whole story
DNA sequencing has significantly enhanced our understanding of historical disease outbreaks by allowing scientists to analyze pathogens' genomes. This technique helps trace the origins and spread of diseases like COVID-19 and Ebola. However, genomic data alone cannot explain the full context of outbreaks, necessitating the integration of historical and environmental information.
- ▪DNA sequencing enables scientists to read a pathogen's genetic material, providing insights into its origins and spread.
- ▪Researchers have successfully used sequencing to track various outbreaks, including COVID-19 and Ebola.
- ▪Genomic data has limitations and must be combined with historical records and other investigations to fully understand outbreaks.
