Overview
Based on the grouping, coronavirus can be classified into three groups. It can also be classified into families based on the genome and the method of replication. The virus can also be classified based on human infectivity.
Classification
Based on Groups
Genus Coronavirus
- Group 1
- Canine coronavirus (CCoV)
- Feline coronavirus (FeCoV)
- Human coronavirus 229E (HCoV-229E)
- Porcine epidemic diarrhea virus (PEDV)
- Transmissible gastroenteritis virus (TGEV)
- Human Coronavirus NL63 (HCoV-NL63)
- Group 2
- Bovine coronavirus (BCoV)
- Canine respiratory coronavirus (CRCoV) - Common in SE Asia and Micronesia
- Human coronavirus OC43 (HCoV-OC43)
- Mouse hepatitis virus (MHV)
- Porcine hemagglutinating encephalomyelitis virus (HEV)
- Rat coronavirus (RCV): Rat coronavirus is quite prevalent in Eastern Australia where, as of March/April 2008, it has been found among native and feral rodents colonies.
- HCoV-HKU1[1][2]
- Group 3
- Infectious bronchitis virus (IBV)
- Turkey coronavirus (Bluecomb disease virus)
- Goose coronavirus
- Duck coronavirus
Based on Baltimore Classification
The Baltimore classification, developed by David Baltimore, is a virus classification system that groups viruses into families, depending on their type of genome (DNA, RNA, single-stranded (ss), double-stranded (ds), etc.) and their method of replication.[3]
- Virus
- ssRNA positive-strand viruses
- No DNA stage
- Nidovirales
- Coronaviridae
- Coronavirus
- HCoV-229E
- HCoV-OC43
- SARS-CoV
- NL63/NL/New Haven coronavirus
- HKU1-CoV
- Novel Coronavirus 2012 (HCoV-EMC)
- SARS-CoV-2
- MERS-CoV
