SARS-CoV-2 is the seventh known coronavirus to infect people, after 229E, NL63, OC43, HKU1, MERS-CoV, and the original SARS-CoV.  Like the SARS-related coronavirus implicated in the 2003 SARS outbreak, SARS‑CoV‑2 is a member of the subgenus Sarbecovirus ( beta-CoV lineage B).   Coronaviruses undergo frequent recombination.

SARS-CoV-2 The virus that causes a respiratory disease called coronavirus disease 19 (see definition COVID-19). SARS-CoV-2 is part of a larger family of viruses called coronaviruses, including SARS-CoV, which led to an epidemic that affected 26 countries and resulted in more than 8000 cases in 2003.

SARS-CoV-2 reinfection has been reported in people after an initial diagnosis of infection; therefore, clinicians should consider using a NAAT for those who have recovered from a previous infection and who present with symptoms that are compatible with SARS-CoV-2 infection if there is no alternative diagnosis (BIII).
The virion of SARS-CoV-2 looks like a solar corona by transmission electron microscopy imaging: the virus particle is in a spherical shape with some pleomorphism; the diameter of the virus particles range from 60 to 140 nm with distinctive spikes about 8 to 12 nm in length 8.
SARS-CoV-2 testing may be incorporated into a comprehensive approach to reducing transmission that also includes screening for symptoms and contact tracing. When combined, these strategies can identify people infected with SARS-CoV-2 so that actions can be taken to slow and stop the spread of the virus.
SARS-CoV-2 (Abkürzung für englisch severe acute respiratory syndrome coronavirus type 2 ‚  Schweres-akutes-Atemwegssyndrom-Coronavirus Typ 2) ist ein Betacoronavirus, das nach dem erstmaligen Nachweis zunächst auch als neuartiges Coronavirus oder nur als Coronavirus bezeichnet wurde. Es ist mit dem Betacoronavirus SARS-CoV-1 verwandt ...
