The influenza virus has become so deadly, due to its ability to mutate seasonally, through a process called reassortment. This involves the recombination of large genetic segments from several viral strains, which causes small genetic changes to be passed on to create a new type of daughter virus (4). Influenza viruses can do this by antigenic drift, which is when” dominant strains from the previous year have changed its surface structure enough to make the effectiveness of the flu vaccine…

The Variola Virus The Variola virus, which exists in two strains, Variola Minor and Variola Major, has been the cause of one of humanity’s most devastating diseases -- smallpox. This disease is around 200-400 nanometers small and is oval or brick-shaped. The Variola virus, and including all other viruses, are not considered alive. They reproduce by coming in contact with a host cell (for the Variola strains, human animal cells) and injecting their DNA into the host to take its functions over.…
