Virus classification is the process by which viruses are categorized and organized into distinct groups based on their shared characteristics, such as genetic composition, structure, and mode of replication. This classification system helps researchers better understand the diversity of viruses and how they are related to one another. Viruses are currently classified into different families, genera, and species based on criteria established by the International Committee on Taxonomy of Viruses (ICTV). This classification system allows scientists to study and compare viruses more effectively, aiding in the development of vaccines, treatments, and prevention strategies for viral diseases.
