Coronaviruses are a group of related RNA viruses that cause diseases in mammals and birds. In humans and birds, they cause respiratory tract infections that can range from mild to lethal. Mild illnesses in humans include some cases of the common cold, while more lethal varieties can cause SARS, MERS, and COVID-19. In cows and pigs they cause diarrhea, while in mice they cause hepatitis and encephalomyelitis.
Murine coronavirus (M-CoV) is a species of coronavirus which infects mice. It is an enveloped, positive-sense, single-stranded RNA virus which enters its host cell by binding to the CEACAM1 receptor. It has, like other coronaviruses from genus Betacoronavirus, subgenus Embecovirus, an additional hemagglutinin esterase (HE) gene.
Pipistrellus bat coronavirus HKU5 is an enveloped, positive-sense single-stranded RNA mammalian Group 2 Betacoronavirus discovered in Japanese Pipistrellus in Hong Kong. This strain of coronavirus is closely related to the newly identified novel MERS-CoV that is responsible for the 2012 Middle East respiratory syndrome-related coronavirus outbreaks in Saudi Arabia, Jordan, United Arab Emirates, the United Kingdom, France, and Italy.
Human coronavirus HKU1 (HCoV-HKU1) is a species of coronavirus in humans. It causes an upper respiratory disease with symptoms of the common cold, but can advance to pneumonia and bronchiolitis. It was first discovered in January 2004 from one man in Hong Kong. Subsequent research revealed it has global distribution and earlier genesis.
Betacoronavirus is one of four genera of coronaviruses. Member viruses are enveloped, positive-strand RNA viruses that infect mammals. The natural reservoir for betacoronaviruses are bats and rodents. Rodents are the reservoir for the subgenus Embecovirus, while bats are the reservoir for the other subgenera.
Human coronavirus OC43 (HCoV-OC43) is a member of the species Betacoronavirus 1, which infects humans and cattle. The infecting coronavirus is an enveloped, positive-sense, single-stranded RNA virus which enters its host cell by binding to the N-acetyl-9-O-acetylneuraminic acid receptor. OC43 is one of seven known coronaviruses to infect humans. It is one of the viruses responsible for the common cold. It has, like other coronaviruses from genus Betacoronavirus, subgenus Embecovirus, an additional shorter spike protein called hemagglutinin esterase (HE).
Alphacoronaviruses (Alpha-CoV) are members of the first of the four genera of coronaviruses. They are positive-sense, single-stranded RNA viruses that infect both humans and mammals. They have spherical virions with club-shaped surface projections and a viral envelope.
Deltacoronavirus (Delta-CoV) is one of the four genera of coronaviruses. It is in the subfamily Orthocoronavirinae of the family Coronaviridae. They are enveloped, positive-sense, single-stranded RNA viruses. Deltacoronaviruses infect mostly birds and some mammals.
Gammacoronavirus (Gamma-CoV) is one of the four genera of coronaviruses. It is in the subfamily Orthocoronavirinae of the family Coronaviridae. They are enveloped, positive-sense, single-stranded RNA viruses of zoonotic origin. Coronaviruses infect both animals and humans.
Human coronavirus 229E (HCoV-229E) is a species of coronavirus which infects humans and bats. It is an enveloped, positive-sense, single-stranded RNA virus which enters its host cell by binding to the APN receptor. Along with Human coronavirus OC43, it is one of the viruses responsible for the common cold. HCoV-229E is a member of the genus Alphacoronavirus and subgenus Duvinacovirus.
Tylonycteris bat coronavirus HKU4 is an enveloped, positive-sense single-stranded RNA virus mammalian Group 2 Betacoronavirus that has been found to be genetically related to the Middle East respiratory syndrome-related coronavirus (MERS-CoV) that is responsible for the 2012 Middle East respiratory syndrome coronavirus outbreak in Saudi Arabia, Jordan, United Arab Emirates, the United Kingdom, France, and Italy.
Rhinolophus bat coronavirus HKU2 is a novel enveloped, single-stranded positive-sense RNA virus species in the Alphacoronavirus, or Group 1, genus with a corona-like morphology.
Scotophilus bat coronavirus 512 is an enveloped, single-stranded positive-sense RNA virus species in the Alphacoronavirus, or Group 1, genus with a corona-like morphology. It was isolated from a lesser Asiatic yellow house bat discovered in southern China.
Coronavirus HKU15, sometimes called Porcine coronavirus HKU15 is a virus first discovered in a surveillance study in Hong Kong, China, and first reported to be associated with porcine diarrhea in February 2014. In February 2014, PorCoV HKU15 was identified in pigs with clinical diarrhea disease in the U.S. state of Ohio. The complete genome of one US strain has been published. Since then, it has been identified in pig farms in Canada. The virus has been referred to as Porcine coronavirus HKU15, Swine deltacoronavirus and Porcine deltacoronavirus.
Embecovirus is a subgenus of coronaviruses in the genus Betacoronavirus. The viruses in this subgenus, unlike other coronaviruses, have a hemagglutinin esterase (HE) gene. The viruses in the subgenus were previously known as group 2a coronaviruses.
Merbecovirus is a subgenus of viruses in the genus Betacoronavirus. The viruses in this subgenus were previously known as group 2c coronaviruses.
Nobecovirus is a subgenus of viruses in the genus Betacoronavirus. The viruses in the group were previously known as group 2d coronaviruses.
This article lists known coronavirus diseases caused by viruses in the coronavirus subfamily. Coronaviruses are a group of related RNA viruses that cause diseases in mammals and birds. In humans and birds, the group of viruses cause respiratory tract infections that can range from mild to lethal. Mild illnesses in humans include some cases of the common cold, while more lethal varieties can cause SARS, MERS, and COVID-19. As of 2020, 45 species are registered as coronaviruses, whilst 11 diseases have been identified, as listed below.
Beluga whale coronavirus SW1 is a mammalian Gammacoronavirus, an RNA virus, discovered through genome sequencing in the liver of a single deceased beluga whale and first described in 2008. This was the first description of the complete genome of a coronavirus found in a marine mammal.
The history of coronaviruses is a reflection of the discovery of the diseases caused by coronaviruses and identification of the viruses. It starts with the first report of a new type of upper-respiratory tract disease among chickens in North Dakota, US, in 1931. The causative agent was identified as a virus in 1933. By 1936, the disease and the virus were recognised as unique from other viral disease. The became known as infectious bronchitis virus (IBV), but later officially renamed as Avian coronavirus.
