Abstract
Viruses are infectious agents that contain proteins and nucleic acids. The nucleic acids are usually either RNA or DNA, but not both. Viruses are dependent on other organisms for replication; some scientists have suggested that they are not truly living organisms [1]. They are submicroscopic in size measuring from a few nanometers to a few hundred nanometers in maximum length. Their shapes can vary from simple, helical, and icosahedral to more complex forms. Viruses can be visualized with the electron microscope with or without negative staining, so it was not until the late 1930s that scientist were able to visualize viruses after the development of the electron microscope. Some viruses discussed in this chapter include paramyxo virus, measles virus, respiratory syncytial virus, gastroenteritis virus, rhabdovirus, and coronavirus. Interestingly, similarities and differences have been observed in viral pandemics occuring in 1918 and 2019. Research over the past few decades have linked multiple human cancers to viruses including cervical cancer and head and neck squamous cell cancer.
