Human coronaviruses (CoV) are a large family of viruses that can cause a variety of illnesses ranging from the common cold to severe diseases like Middle East respiratory syndrome (MERS-CoV) and Severe Acute respiratory syndrome (SARS-CoV). The World Health Organization says Novel Coronavirus (nCoV) is a new strain that had not been previously identified in humans until late 2019. Human coronavirus was first discovered in 1965 and accounts for many cases of the common cold.
