Coronovirus

Coronovirus

Coronaviruses are a large group of RNA viruses, hundreds of which have been identified to date by scientists. Coronaviruses may cause illness in animals or humans.  In humans, several coronaviruses are known to cause respiratory infections ranging from the common cold to more severe diseases such as Middle East Respiratory Syndrome (MERS) and Severe Acute Respiratory Syndrome (SARS). The most recently discovered coronavirus causes coronavirus disease COVID-19.

The term corona means something that resembles a crown; the spike-like proteins that stud the membranes of these viruses make them look like crowns. These viruses have been known to be infectious for decades but were initially identified only in mild illnesses, such as the common cold.
