Viruses are classified based on their structure, genetic material, and method of replication. The main categories include DNA viruses and RNA viruses, depending on their genetic material. DNA viruses, like the herpesvirus, have DNA as their genetic material, while RNA viruses, like the influenza virus, have RNA.

Viruses can also be classified by shape, such as helical (spiral-shaped), icosahedral (spherical), or complex (a mix of shapes). Additionally, viruses are categorized by their mode of transmission, such as respiratory (like the flu), bloodborne (like HIV), or vector-borne (like Zika, transmitted by mosquitoes). This classification helps in understanding and treating different viral infections.
