Genomic surveillance is a field of research that involves the monitoring and analysis of genetic information from organisms, typically pathogens such as viruses and bacteria. This information is used to track the evolution and spread of these organisms, and to inform public health measures such as vaccination strategies and outbreak control. Genomic surveillance involves sequencing the genomes of organisms, analyzing these sequences to identify mutations and genetic variations, and using this information to understand how diseases are transmitted and how they are evolving. This can help researchers and public health officials to track the spread of pathogens, identify emerging threats, and develop targeted interventions.
