What is CoronaVirus?
Coronaviruses (CoV) are a large family of viruses that cause illness ranging from the common cold to more severe diseases such as Middle East Respiratory Syndrome (MERS-CoV) and Severe Acute Respiratory Syndrome (SARS-CoV). A novel coronavirus (nCoV) is a new strain that has not been previously identified in humans.
Coronaviruses are zoonotic, meaning they are transmitted between animals and people. Detailed investigations found that SARS-CoV was transmitted from civet cats to humans and MERS-CoV from dromedary camels to humans. Several known coronaviruses are circulating in animals that have not yet infected humans.
History of Coronavirus
Coronaviruses are a group of viruses that cause diseases in mammals and birds. In humans, the viruses cause respiratory infections – including the common cold – which are typically mild. Rarer forms such as SARS, MERS and the novel coronavirus causing the 2019–20 Wuhan coronavirus outbreak can be lethal. In cows and pigs coronaviruses cause diarrhea. In chickens they cause an upper respiratory disease.
Coronaviruses are in the subfamily Orthocoronavirinae in the family Coronaviridae, in the order Nidovirales (De Groot , et al., 2011). 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 26 to 32 kilobases, the largest for an RNA virus.
The name "coronavirus" is derived from the Latin corona, meaning crown or halo, which refers to the characteristic appearance of the virus particles (virions): they have a fringe reminiscent of a crown or of a solar corona
Discovery
Coronaviruses were discovered in the 1960s (wikipedia, 2020). The earliest ones discovered were infectious bronchitis virus in chickens and two viruses from the nasal cavities of human patients with the common cold that were subsequently named human coronavirus 229E and human coronavirus OC43. Other members of this family have since been identified, including SARS-CoV in 2003, HCoV NL63 in 2004, HKU1 in 2005, MERS-CoV in 2012, and 2019-nCoV in 2019; most of these have been involved in serious respiratory tract infections.
The Wuhan CoronaVirus
In December 2019, a pneumonia outbreak was reported in Wuhan, China. On 31 December 2019, the outbreak was traced to a novel strain of coronavirus, which was given the interim name 2019-nCoV by the World Health Organization (WHO).
As of 9 February 2020, there have been 814 confirmed deaths and more than 37,590 confirmed cases in the coronavirus pneumonia outbreak. The Wuhan strain has been identified as a new strain of Betacoronavirus from group 2B with an approximately 70% genetic similarity to the SARS-CoV. The virus was suspected to have originated in snakes, but many leading researchers disagree with this conclusion. The virus has a 96% similarity to a bat coronavirus, so an origin in bats is widely suspected. (The Editorial Board, February 9, 2020)
Symptoms of CoronaVirus
Common signs of infection include
1. Respiratory symptoms such as fever, cough, shortness of breath and breathing difficulties.
2. In more severe cases, infection can cause pneumonia, severe acute respiratory syndrome, kidney failure and even death.
How to Prevent Spread of CoronaVirus
Standard recommendations to prevent infection spread include
1. regular hand washing
2. covering mouth and nose when coughing and sneezing,
3. thoroughly cooking meat and eggs.
4. Avoid close contact with anyone showing symptoms of respiratory illness such as coughing and sneezing

Thanks so much much.... You have saved a life 🤸
Welcome... Make sure to tell your friends about Solutionwheels. That's the important thing
The virus has killed 1,017people with 42000+ Chinese infected.
Quite alarming.. But they've changed the people looking into the. Situation. And some vaccines in view. Hoping it gets better, can't afford to lose 42000 people to the virus
