Viruses are classified in several ways: by factors such as their core content (
[link] and
[link] ), the structure of their capsids, and whether they have an outer envelope. The type of genetic material (DNA or RNA) and its structure (single- or double-stranded, linear or circular, and segmented or non-segmented) are used to classify the virus core structures.
Non-segmented: genome consists of a single segment of genetic material
Segmented: genome is divided into multiple segments
Parainfluenza viruses
Influenza viruses
Viruses can also be classified by the design of their capsids (
[link] and
[link] ). Capsids are classified as naked icosahedral, enveloped icosahedral, enveloped helical, naked helical, and complex (
[link] and
[link] ). The type of genetic material (DNA or RNA) and its structure (single- or double-stranded, linear or circular, and segmented or non-segmented) are used to classify the virus core structures (
