CoVs are a large family of viruses that cause illness ranging from the common cold caused by four human HCoVs that are endemic globally are HCoV-229E, HCoV-NL63, HCoV-HKU1 as well as HCoV-OC43, and more severe diseases caused by Middle East Respiratory Syndrome (MERS-CoV) and Severe Acute Respiratory Syndrome (SARS-CoV). The novel coronavirus (nCoV) is a new strain that has not been previously identified in humans. CoVs are transmitted between animals and humans. Several known CoVs are circulating in animals that have not yet infected humans.
Respiratory symptoms, fever, cough, shortness of breath and breathing difficulties are the common signs of infection. Infection can cause pneumonia, severe acute respiratory syndrome, kidney failure and even death, in more severe cases.
To prevent infection spread, regular hand washing, covering mouth and nose when coughing and sneezing, thoroughly cooking meat and eggs are the standard recommendations. Close contact with anyone showing symptoms of respiratory illness such as coughing and sneezing must be restricted.

WHO has published its interim guidance for laboratory biosafety related to 2019-nCoV/COVID-19/SARS-CoV-2, which is available from the following page and the link below:
Applying standard precautions for all patients. Standard precautions include:
The etiologic agent responsible for the cluster of pneumonia cases in Wuhan has been identified as a novel betacoronavirus, (in the same family as SARS-CoV and MERS-CoV) via next generation sequencing (NGS) from cultured virus or directly from samples received from several pneumonia patients.
Electron microscopy revealed a virus with a characteristic crown morphology: a coronavirus. Working directly from sequence information, the team developed a series of genetic amplification (PCR) assays used by laboratories associated with the China CDC to detect several dozen cases as of today.
