Human coronavirus 229E

Human coronavirus 229E (HCoV-229E) is a species of coronavirus which infects humans and bats. [1] It is an enveloped, positive-sense, single-stranded RNA virus which enters its host cell by binding to the APN receptor. [2] Along with Human coronavirus OC43 (a member of the Betacoronavirus genus), it is one of the viruses responsible for the common cold. [3] [4] HCoV-229E is a member of the genus Alphacoronavirus and subgenus Duvinacovirus. [5] [6]

Transmission

HCoV-229E transmits via droplet-respiration and fomites.

Signs and symptoms

HCoV-229E is associated with a range of respiratory symptoms, ranging from the common cold to high-morbidity outcomes such as pneumonia and bronchiolitis. However, such high morbidity outcomes are almost always seen in cases with co-infection with other respiratory pathogens; there is a single published case report to date of a 229E infection that caused acute respiratory distress syndrome (ARDS) in an otherwise healthy patient having no detectable co-infection with another pathogen. [7] HCoV-229E is also among the coronaviruses most frequently codetected with other respiratory viruses, particularly with human respiratory syncytial virus (HRSV). [8] [9] [10]

Epidemiology

HCoV-229E is one of the seven human coronaviruses which include HCoV-NL63, HCoV-OC43, HCoV-HKU1, MERS-CoV, SARS-CoV-1, and SARS-CoV-2 and are globally distributed. [11] [12] However, the viruses were detected in different parts of the world at different times of the year. [13] [14] [15] A NCBI-study found a previous HCoV-229E infection in 42.9% – 50.0% of children of 6–12 months of age and in 65% of those 2.5–3.5 years of age. [16]

Virology

HCoV-229E is one of seven known coronaviruses to infect humans. The other six are: [17]

Research

Chloroquine, a zinc ionophore, inhibits the replication of Human coronavirus 229E in cell culture. [18]

Human HCoV-229E, and human HCoV-NL63, likely originated from bats. [19]

History

A researcher at the University of Chicago, Dorothy Hamre, first identified 229E in 1965. [20] [21]

<i>Murine coronavirus</i> Species of virus

Murine coronavirus (M-CoV) is a virus in the genus Betacoronavirus that infects mice. Belonging to the subgenus Embecovirus, murine coronavirus strains are enterotropic or polytropic. Enterotropic strains include mouse hepatitis virus (MHV) strains D, Y, RI, and DVIM, whereas polytropic strains, such as JHM and A59, primarily cause hepatitis, enteritis, and encephalitis. Murine coronavirus is an important pathogen in the laboratory mouse and the laboratory rat. It is the most studied coronavirus in animals other than humans, and has been used as an animal disease model for many virological and clinical studies.

Bovine coronavirus is a coronavirus which is a member of the species Betacoronavirus 1. The infecting virus is an enveloped, positive-sense, single-stranded RNA virus which enters its host cell by binding to the N-acetyl-9-O-acetylneuraminic acid recepter. Infection causes calf enteritis and contributes to the enzootic pneumonia complex in calves. It can also cause winter dysentery in adult cattle. It can infect both domestic and wild ruminants and has a worldwide distribution. Transmission is horizontal, via oro-fecal or respiratory routes. Like other coronaviruses from genus Betacoronavirus, subgenus Embecovirus, it has a surface protein called hemagglutinin esterase (HE) in addition to the four structural proteins shared by all coronaviruses.

<span class="mw-page-title-main">MERS-related coronavirus</span> Species of virus

Middle East respiratory syndrome–related coronavirus (MERS-CoV), or EMC/2012 (HCoV-EMC/2012), is the virus that causes Middle East respiratory syndrome (MERS). It is a species of coronavirus which infects humans, bats, and camels. The infecting virus is an enveloped, positive-sense, single-stranded RNA virus which enters its host cell by binding to the DPP4 receptor. The species is a member of the genus Betacoronavirus and subgenus Merbecovirus.

Novel coronavirus (nCoV) is a provisional name given to coronaviruses of medical significance before a permanent name is decided upon. Although coronaviruses are endemic in humans and infections normally mild, such as the common cold, cross-species transmission has produced some unusually virulent strains which can cause viral pneumonia and in serious cases even acute respiratory distress syndrome and death.

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.

<i>Human coronavirus HKU1</i> Species of virus

Human coronavirus HKU1 (HCoV-HKU1) is a species of coronavirus in humans and animals. 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.

<i>Betacoronavirus</i> Genus of viruses

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.

<span class="mw-page-title-main">Coronavirus diseases</span> List of Coronavirus diseases

Coronavirus diseases are caused by viruses in the coronavirus subfamily, 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 2021, 45 species are registered as coronaviruses, whilst 11 diseases have been identified, as listed below.

<span class="mw-page-title-main">History of coronavirus</span> History of the virus group

The history of coronaviruses is an account of the discovery of the diseases caused by coronaviruses and the diseases they cause. It starts with the first report of a new type of upper-respiratory tract disease among chickens in North Dakota, U.S., 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. They became known as infectious bronchitis virus (IBV), but later officially renamed as Avian coronavirus.

Civet SARS-CoV is a coronavirus associated with Severe acute respiratory syndrome coronavirus (SARS-CoV), which infected humans and caused SARS events from 2002 to 2003. It infected the masked palm civet. The severe acute respiratory syndrome coronavirus (SARS-CoV) is highly similar, with a genome sequence similarity of about 99.8%. Because several patients infected at the early stage of the epidemic had contact with fruit-eating Japanese Raccoon Dog in the market, fruit-eating Tanuki may be a direct source of human SARS coronavirus. At the end of 2003, four more people in Guangzhou, China were infected with the disease. Sequence analysis found that the similarity with the Tanuki virus reached 99.9%, and the SARS coronavirus was also caused by cases of Tanuki transmission.

<span class="mw-page-title-main">ORF3a</span> Gene found in coronaviruses of the subgenus Sarbecovirus

ORF3a is a gene found in coronaviruses of the subgenus Sarbecovirus, including SARS-CoV and SARS-CoV-2. It encodes an accessory protein about 275 amino acid residues long, which is thought to function as a viroporin. It is the largest accessory protein and was the first of the SARS-CoV accessory proteins to be described.
