What Is Coronavirus

The coronavirus is a big family of pathogens that only infect animals. A coronavirus gets its name from how these pathogens exhibit spikes that resemble the angles of a crown The name coronavirus is derived from the Latin corona, meaning crown or halo, which refers to the characteristic appearance reminiscent of a crown or a solar corona around the virions (virus particles) when viewed under two-dimensional transmission electron microscopy, due to the surface covering in club-shaped protein spikes. Some of them cause mild illnesses like the common cold. Others can cause fatal infections.. They are enveloped viruses with a positive-sense single-stranded RNA genome and a nucleocapsid of helical symmetry. The genome size of coronaviruses ranges from approximately 27 to 34 kilobases, the largest among known RNA viruses. This is a class of virus that is known to mutate easily. MERS and SARS both began as infections in bats before mutating to infect humans. They had evolved in their animal hosts to infect humans. The type that infects humans was first identified in the 1960s. Since then, seven human-infecting types of coronavirus have been identified, including 2019-nCoV, also known as Wuhan Coronavirus. This virus resembles other serious human coronavirus types MERS and SARS in that all belong to the beta subgrouping of virus. They are associated with the common cold, pneumonia, and severe acute respiratory syndrome (SARS) and can also affect the gut.

Transmission

Coronaviruses are thought to spread most often by respiratory droplets, such as droplets in a coughs for ten minutes or longer or sneeze exposure as being within six feet of an infected person, by touching a surface seats on buses or trains or desks in school or object that has the virus on it and then touching their own mouth, nose, or possibly their eyes. When an infected person coughs or sneezes, they release droplets of saliva or mucus. These droplets can fall on people in the vicinity and can be either directly inhaled or picked up on the hands then transferred when someone touches their face, causing infection.
