    en.wikipedia.org/wiki/History_of_virology

    Viruses were expected to be small, but the range of sizes came as a surprise. Some were only a little smaller than the smallest known bacteria, and the smaller viruses were of similar sizes to complex organic molecules. [14] In 1935, Wendell Stanley examined the tobacco mosaic virus and found it was mostly made of protein. [15]

    There are more than 500 species of arboviruses, but in the 1930s only three were known to cause disease in humans: yellow fever virus, dengue virus and Pappataci fever virus. [202] More than 100 of such viruses are now known to cause human diseases including encephalitis. [203] Yellow fever is the most notorious disease caused by a flavivirus ...

    en.wikipedia.org/wiki/Viral_evolution

    Viral evolution is a subfield of evolutionary biology and virology concerned with the evolution of viruses. [1] [2] Viruses have short generation times, and many—in particular RNA viruses—have relatively high mutation rates (on the order of one point mutation or more per genome per round of replication).

    Viruses are an established cause of cancer in humans and other species. Viral cancers occur only in a minority of infected persons (or animals). Cancer viruses come from a range of virus families, including both RNA and DNA viruses, and so there is no single type of " oncovirus " (an obsolete term originally used for acutely transforming ...

    The human virome is a part of human bodies and will not always cause harm. [23] Many latent and asymptomatic viruses are present in the human body all the time. Viruses infect all life forms; therefore the bacterial, plant, and animal cells and material in the gut also carry viruses. [6]

    The researchers looked at nearly 12 million virus genomes and detected almost 3,000 instances of viruses jumping from one species to another. Of those, 79% involved a virus going from one animal ...

    A representation by Robert Seymour of the cholera epidemic depicts the spread of the disease in the form of poisonous air.. The miasma theory was the predominant theory of disease transmission before the germ theory took hold towards the end of the 19th century; it is no longer accepted as a correct explanation for disease by the scientific community.
