Overview

Coronavirus disease was first described in 1931, with the first coronavirus (HCoV-229E) isolated from humans in 1965. Until the outbreak of severe acute respiratory syndrome in late 2002, only two human coronaviruses (HCoV) were known - HCoV-229E and HCoV-OC43. Once the SARS coronavirus (SARS-CoV) had been identified, two further human coronaviruses were identified. Three groups of coronaviruses exist: group 1 (HCoV-229E and HCoV-NL63), group 2 (HCoVOC43 and HCoV-HKU1), group 3 (no human CoVs as yet). SARS-CoV is an outlier to all three groups, although some place it in group 2. Coronaviruses possess a unique morphology, the name being derived from the outer fringe, or corona of embedded envelope protein. Members of the family Coronaviridae cause a wide spectrum of animal and human diseases. Distinctively, replication of the RNA genome proceeds through the generation of a nested set of viral mRNA molecules. Until 2003, coronaviruses attracted little interest beyond causing mild upper respiratory tract infections. This changed dramatically in 2003 with the zoonotic SARS-CoV and the more recent emergence of MERS-CoV has confirmed the coronaviruses as significant causes of severe respiratory disease. Currently or presently no vaccine to protect against the virus. Treatments and vaccines are in development currently by researchers and there is an urgent need of a vaccine to prevent it develop into a pandemic. The good news is that corona virus does not mutate and is easy to control.
