Detailed explanation-1: -The World Health Organization (WHO) has decided to name the disease caused by the novel coronavirus “COVID-19” and refers to the virus that causes it as the “COVID-19 virus.” CO for corona, VI for virus, D for disease, and 19 for the year the outbreak was first recognized, late in 2019.
Detailed explanation-2: -The first evidence of the existence of viruses came from experiments with filters that had pores small enough to retain bacteria. In 1892, Dmitri Ivanovsky used one of these filters to show that sap from a diseased tobacco plant remained infectious to healthy tobacco plants despite having been filtered.
Detailed explanation-3: -Beijerinck, in 1898, was the first to call ‘virus’, the incitant of the tobacco mosaic. He showed that the incitant was able to migrate in an agar gel, therefore being an infectious soluble agent, or a ‘contagium vivum fluidum’ and definitively not a ‘contagium fixum’ as would be a bacteria.
Detailed explanation-4: -Dmitri Ivanowsky in 1892. He recognized an infectious agent, which caused tobacco mosaic disease and were smaller than bacteria. M.W. Beijerinek in 1898 called the filter ‘Contagium vivum fluidum’ and named it the ‘virus’.
