    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]

    One way that viruses have been able to spread is with the evolution of virus transmission. The virus can find a new host through: [32] Droplet transmission: the virus is spread to a new host through bodily fluids (an example is the influenza virus) [33] Airborne transmission: the virus is passed on through the air (an example is viral ...

    en.wikipedia.org/wiki/History_of_coronavirus

    The history of coronaviruses is an account of the discovery of the diseases caused by coronaviruses and the diseases they cause. It starts with the first report of a new type of upper-respiratory tract disease among chickens in the U.S. state of North Dakota, in 1931. The causative agent was identified as a virus in 1933.

    A virus is a submicroscopic infectious agent that replicates only inside the living cells of an organism. [1] Viruses infect all life forms, from animals and plants to microorganisms, including bacteria and archaea. [2] [3] Viruses are found in almost every ecosystem on Earth and are the most numerous type of biological entity.

    In 1935, American biochemist and virologist Wendell Meredith Stanley examined the tobacco mosaic virus (TMV) and found it to be mainly made from protein. [7] A short time later, this virus was shown to be made from protein and RNA. [8] Rosalind Franklin developed X-ray crystallographic pictures and determined the full structure of TMV in 1955. [9]

    In addition, the same viruses were prevalent in multiple body habitats within individuals. For instance, the beta- and gamma-papillomaviruses were the viruses most commonly found in the skin and the nose (anterior nares; see Figure 4A,B), which may reflect proximity and similarities in microenvironments that support infection with these viruses ...

    A fatal virus has been discovered in shrews in Alabama, sparking concerns about potential contagion to humans. The Camp Hill virus was discovered by researchers at The University of Queensland.

  9. Social history of viruses - Wikipedia

    en.wikipedia.org/wiki/Social_history_of_viruses

    The nature of viruses remained unknown until the invention of the electron microscope in the 1930s, when the science of virology gained momentum. In the 20th century many diseases both old and new were found to be caused by viruses. There were epidemics of poliomyelitis that were only controlled following the development of a vaccine in the 1950s.
