The Novel Coronavirus Disease (COVID-19) is a virus that was first identified on January 13, 2020, as a result of research conducted in a group of patients who developed respiratory symptoms (fever, cough, shortness of breath) in Wuhan Province, China, in late December.

The outbreak was initially detected in those found in the seafood and animal market in this region. Later, it spread from person to person and spread to other cities in Hubei province, especially in Wuhan, other provinces of the People's Republic of China and other world countries.

Coronaviruses are a large family of viruses that can cause disease in animals or humans. In humans, several coronaviruses are known to cause respiratory infections, from the common cold to more severe diseases such as Middle East Respiratory Syndrome (MERS) and Severe Acute Respiratory Syndrome (SARS). Novel Coronavirus Disease is caused by the SAR-CoV-2 virus.
