Virus classification
Group: Group IV ((+)ssRNA)
Order: Nidovirales
Family: Coronaviridae
Subfamily: Coronavirinae
Genus: Betacoronavirus
Species: HCoV-EMC/2012

HCoV-EMC/2012, or Human Coronavirus Erasmus Medical Center/2012 is the name of a novel strain of coronavirus isolated from the sputum of the first person to become infected with what was later named Middle East respiratory syndrome coronavirus, or MERS-CoV.[1][2][3][4]

Natural reservoir[edit]

An investigation of bat roosts in Bisha, the hometown of the index patient, by the Saudi Ministry of Health discovered an Egyptian tomb bat in a large roost close to the index patient's home. Phylogenetic analysis showed a 100% match between the virus isolated from the bat and HCoV-EMC/2012 isolated from the index patient.[5]

Virology[edit]

HCoV-EMC/2012 is the sixth coronavirus known to infect humans and the first human virus within betacoronavirus lineage C. It is a new genotype which is related to bat coronaviruses, specifically an Egyptian tomb bat, and is not the same beta-CoV as the SARS-CoV, but is distantly related.[3][6]
