Coronaviruses (Cov) is a family of viruses that cause more serious illnesses from the common cold, such as Middle East Respiratory Syndrome (MERS – CoV) and Severe Acute Respiratory Syndrome (Severe Acute Respiratory Syndrome, SARS-CoV). As a result of extensive researches, it has been revealed that SARS-CoV is infected by musk cats and MERS-CoV is transmitted from single humped camels. There are many coronaviruses that have not been transmitted to humans yet, but are detected in animals.

Subtypes of coronaviruses circulating in humans (HCoV-229E, HCoV-OC43, HCoV-NL63 and HKU1-CoV) are mostly viruses that cause colds. SARS-CoV emerged as a previously unknown virus in 2003 as the first international health emergency of the 21st century, causing hundreds of people to die.

Later, the name of 2019-nCoV disease was accepted as COVID-19.
