A virus is essentially a tiny submicroscopic viral agent which copies itself within an organism’s living cells. Most viruses infect only life forms, such as bacteria and plants, whereas others can infect cells of all types and even the earthworms. Viruses are capable of spreading from one cell to another by means of glycoprotein virus-like receptors (GVSRs) on the outer surface of a cell. Other characteristics of a virus include protein molecules, double-stranded messenger ribonucleic acid, and envelope globular protein.


The most common form of virus is the enveloped virus, which enters the body through a fluid-filled cell, generally the lymphatic system or the gastrointestinal tract. Enveloped viruses often replicate rapidly in the environment, causing disease symptoms after they multiply. When a nonbacterial virus causes infection within a living cell, it is called an infective agent. Some viruses that cause infection in living cells are called primate virus, herpes virus, hepatitis virus, and swine flu viruses. The word virus derives from a Greek term which means a single letter placed before a tail. Enzymes and proteins within an organism also provide an important role in viral infection; for example, viral RNases and ligases which catalyze various chemical reactions that help the virus to gain access to a particular protein sequence within a living cell.

The newly identified Nipah virus, a genus of retroviruses, has emerged as the Nipah-related virus which has potentially gained the most scientific attention. In the past, the virus was referred to as strain Nipah-1/Sporvite, but after sequencing and testing, scientists revealed that the virus was actually distinct species. The name change from strain to strain was based on the fact that each individual isolate was unique; a member of the genus Nipah-1 had variable genetic material which allowed scientists to distinguish between strains. An example of a strain is Nipah-1/Sporvite, which contained an amino acid composition that is similar to the capsid (protein complexes) in the sars-cov-2, one of the major strains of the virus.

Based on its discovery, scientists have now labeled the virus as a genus in order to reflect the physical structure of the virus. The genus name, covid-19, comes from “cavi” (an aquatic algae) and nineteen letters which identify the virus. This identification is based on similarities to the other known genus, Virodymus (which contains two other viruses). Variation in the genetic material of the virus, when compared to other known and isolated viruses, is what led researchers to name the virus as a genus. The name, covid-19, represents the 19 distinct Viruses known to affect humans.

According to the news release, the Nipah-1/Sporvite strain was the first to be identified as causing a type of respiratory syndrome that shares symptoms with some other viruses. This discovery came as a major breakthrough for scientists who have been struggling to develop vaccines against this particular strain. The release states that the next step in this research will be to examine how the Nipah-1/Sporvite strain affects the human immune system.

In previous studies, Nipah-1/Sporvite was thought to be related to a virus which affects amphibians. However, the new study indicates that the virus may be related to the Sars-cov-2 strain of the same family. In addition to this important news release, another paper published on the Nipah outbreak in Australia is noteworthy. This study used archived data on patients in a health care facility in order to show that the highest number of reported Sars-cov-2 infections were those who had never shown any signs of illness before contracting the virus.
