The virus discovered by Chinese experts in early January is now called SARS-CoV-2 because it is similar to the virus that causes severe acute respiratory syndrome (SARS). The disease caused by this new virus is called COVID-19.
Coronavirus is indeed an important virus, almost harmless to humans. It is recognized that there are four colds, and the other two may cause extreme lung infections (SARS and MERS) related to COVID-19.
Like all viruses, SARS-CoV-2 requires biological cells to multiply. The virus also appears to target lung cells and may also target other cells in the respiratory program. Cells infected by the virus produce excess virus particles, which are then spread to other people through coughing.
