Viral genomics is a field of study that focuses on the genetic makeup of viruses, including their genomes, genetic variation, and evolution. Researchers in this area aim to understand the molecular characteristics of viruses, how they infect host cells, replicate, and evolve over time. This research is critical for developing diagnostic tools, vaccines, and antiviral treatments to combat viral infections and diseases. Viral genomics also plays a key role in tracking the spread of viruses, such as during outbreaks or pandemics, and identifying potential new threats to public health.
