Coronaviruses (CoVs), enveloped positive-sense RNA viruses, are characterized by club-like spikes that project from their surface, an unusually large RNA genome, and a unique replication strategy. Coronaviruses cause a variety of diseases in mammals and birds ranging from enteritis in cows and pigs and upper respiratory disease in chickens to potentially lethal human respiratory infections.

Coronaviruses (CoVs) (order Nidovirales, family Coronaviridae, subfamily Coronavirinae) are enveloped viruses with a positive sense, single-stranded RNA genome. With genome sizes ranging from 26 to 32 kilobases (kb) in length, CoVs have the largest genomes for RNA viruses.

Coronaviruses are a type of enveloped virus, that is, they are encased within a double-layered lipid (fatty) membrane. Non-enveloped viruses have a hard outer shell called a capsid. Enveloped viruses tend to be sensitive to heat, while capsid-coated viruses are not.

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 (which is also caused by other viruses, predominantly rhinoviruses), while more lethal varieties can cause SARS, MERS, and COVID-19.

Coronavirus virions are spherical to pleomorphic enveloped particles . The envelope is studded with projecting glycoproteins, and surrounds a core consisting of matrix protein enclosed within which is a single strand of positive-sense RNA (Mr 6 × 10 6 ) associated with nucleoprotein.

They are enveloped viruses with a positive-sense single-stranded RNA genome and a nucleocapsid of helical symmetry. The genome size of coronaviruses ranges from approximately 26 to 32 kilobases, among the largest for an RNA virus (second only to a 41-kb nidovirus recently discovered in planaria).

Coronaviruses have enveloped virions (virus particles) that measure approximately 120 nm (1 nm = 10 −9 metre) in diameter. Club-shaped glycoprotein spikes in the envelope give the viruses a crownlike, or coronal, appearance.

Coronaviruses are a large group of enveloped, single-stranded positive-sense RNA viruses that infect a wide range of avian and mammalian species, including humans. The emergence of deadly human coronaviruses, severe acute respiratory syndrome coronavirus (SARS-CoV), and Middle East respiratory syndrome coronavirus (MERS-CoV) have bolstered research in these viral and often zoonotic pathogens.

Coronavirus is enveloped, meaning the virus has coating on the outside of it. As it happens, the envelope means that the virus doesn’t survive well outside of the body—they usually can’t last longer than 24 hours outside of the body and usually only last less than 12.

Are there many coronaviruses?

🏥
All coronaviruses are separated by scientists into four distinct groups: alpha, beta, gamma, and delta coronaviruses. Only seven alpha and beta coronaviruses are known to infect humans. Scientists have named these viruses: 229E (alpha coronavirus) NL63 (alpha coronavirus) OC43 (beta coronavirus) HKU1 (beta coronavirus)

Did coronaviruses come from bats in africa?

🏥
SARS-CoV-2 is the newest of seven coronaviruses found in humans, all of which came from animals, either from bats, mice or domestic animals. Bats were also the source of the viruses causing Ebola, rabies, Nipah and Hendra virus infections, Marburg virus disease, and strains of Influenza A virus.

Coronaviruses (CoVs) are positive-stranded RNA(+ssRNA) viruses with a crown-like appearance under an electron microscope (coronam is the Latin term for crown) due to the presence of spike glycoproteins on the envelope. The subfamily Orthocoronavirinae of the Coronaviridae family (order Nidovirales) classifies into four genera of CoVs: 
How viruses mutate largely has to do with how they make copies of themselves and their genetic material, says Marta Gaglia, an associate professor of molecular biology and microbiology at the School of Medicine. Viruses can have genomes based on DNA or RNA—unlike human genomes, which are made up of DNA, which then can create RNA.

Dr. Cowl says that SARS-CoV-2 is likely more contagious than the viruses that cause influenza and common cold because it is new to humans. Humans have no way to prepare for it, and their immune systems are not ready to fight it. This results in the virus causing more cellular damage and producing more inflammatory cells.
