After tobacco mosaic was recognized as a virus disease, virus infections of many other plants were discovered. [34] The importance of tobacco mosaic virus in the history of viruses cannot be overstated. It was the first virus to be discovered, and the first to be crystallised and its structure shown in detail.
Foot binding (simplified Chinese: 缠足; traditional Chinese: 纏足; pinyin: chánzú), or footbinding, was the Chinese custom of breaking and tightly binding the feet of young girls to change their shape and size. Feet altered by foot binding were known as lotus feet and the shoes made for them were known as lotus shoes.
The virus that causes La Crosse encephalitis was discovered in the 1960s, [210] and West Nile virus arrived in New York in 1999. [211] As of 2010, dengue virus is the most prevalent arbovirus and increasingly virulent strains of the virus have spread across Asia and the Americas. [212]
The smallpox virus devastated numerous societies throughout history before its eradication. There are only two centres in the world authorised by the WHO to keep stocks of smallpox virus: the State Research Center of Virology and Biotechnology VECTOR in Russia and the Centers for Disease Control and Prevention in the United States.

For a given epidemic or pandemic, the average of its estimated death toll range is used for ranking. If the death toll averages of two or more epidemics or pandemics are equal, then the smaller the range, the higher the rank. For the historical records of major changes in the world population, see world population. [3]
The protein has several domains of which domain D1 contains the polio virus binding site. Within this domain, 37 amino acids are responsible for binding the virus. Poliovirus is an enterovirus. Infection occurs via the fecal–oral route, meaning that one ingests the virus and viral replication occurs in the gastrointestinal tract. [42]
Gamma phage, an example of virus particles (visualised by electron microscopy) Virology is the scientific study of biological viruses.It is a subfield of microbiology that focuses on their detection, structure, classification and evolution, their methods of infection and exploitation of host cells for reproduction, their interaction with host organism physiology and immunity, the diseases they ...
Often simply called an antiviral. A class of antimicrobial medication used specifically for treating diseases caused by viral infections rather than ones caused by bacteria or other infectious agents. Unlike most antibiotics, antivirals typically do not destroy their target viruses but instead inhibit their development. They are distinct from virucides. assembly The construction of the virus ...
