Coronavirus: What is it? A group of viruses known as coroviruses can make people sick with respiratory conditions. Because the virus's surface is covered in spikes that resemble crowns, they are known as "corona." Examples of coronaviruses that affect people include the severe acute respiratory syndrome (SARS), Middle East respiratory disease (MERS), and the common cold. SARS-CoV-2, a novel coronavirus strain, was initially discovered in Wuhan, China, in December 2019. Since then, it has spread to every nation on earth.
