A virus is a submicroscopic infectious agent that replicates only inside the living cells of an organism. Viruses can infect all types of life forms, from animals and plants to microorganisms, including bacteria and archaea. Since Dmitri Ivanovsky's 1892 article describing a non-bacterial pathogen infecting tobacco plants, and the discovery of the tobacco mosaic virus by Martinus Beijerinck in 1898, about 5,000 virus species have been described in detail, of the millions of types of viruses in the environment. Viruses are found in almost every ecosystem on Earth and are the most numerous type of biological entity. The study of viruses is known as virology, a subspeciality of microbiology.



Remdesivir, sold under the brand name Veklury, is a broad-spectrum antiviral medication developed by the biopharmaceutical company Gilead Sciences. It is administered via injection into a vein. Remdesivir is being tested as a treatment for COVID‑19, and has been authorized for emergency use in the US, India, Singapore, and approved for use in Japan, the European Union and Australia for people with severe symptoms. It also received approval in the United Kingdom in May 2020; however, it was going to be rationed due to limited supply. It may shorten the time it takes to recover from the infection.
