Coronaviruses are a large family of viruses that usually cause mild to moderate upper-respiratory tract illnesses, like the common cold. However, three new coronaviruses have emerged from animal reservoirs over the past two decades to cause serious and widespread illness and death. There are hundreds of coronaviruses, most of which circulate among such animals as pigs, camels, bats and cats ...

Classification. Coronaviruses (CoVs) are the largest group of viruses belonging to the Nidovirales order, which includes Coronaviridae, Arteriviridae, Mesoniviridae, and Roniviridae families. The Coronavirinae comprise one of two subfamilies in the Coronaviridae family, with the other being the Torovirinae.The Coronavirinae are further subdivided into four genera, the alpha, beta, gamma, and ...

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.

Coronaviruses are a large family of viruses that can infect both animals and humans, first identified in the mid-1960s. They are a respiratory virus named for the crown-like spikes on their surface.

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. Based on genetic and antigenic criteria, CoVs have been organised into three groups: α-CoVs, β-CoVs, and γ-CoVs (Table 1 ...

These include 229E (alpha coronavirus), NL63 (alpha coronavirus), OC43 (beta coronavirus), and HKU1 (beta coronavirus). This group of viruses are known to present only mild respiratory infection, though HKU1 is associated with gastrointestinal infection as well.
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)
"The name 'coronavirus' has to do with what the virus looks like under a microscope," says Dr. Cowl. "'Corona' means crown. All coronaviruses have a similar structure. They are also 'enveloped' viruses, which means they are able to stick to surfaces, but are also able to be killed with disinfectants.

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.
Which of the following is incorrect regarding coronaviruses? A. One type can cause the common cold. B. One type can cause SARS. C. They are common animal viruses in pigs, dogs, cats, and poultry. D. There are no tests to confirm diagnosis. E. There is no specific treatment other than supportive care.
In context, Trump did not say in the passage above that the virus itself was a hoax. He instead said that Democrats’ criticism of his administration’s response to it was a hoax.
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:
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.
Both are caused by coronaviruses that can lead to severe respiratory illness. Even the names of the viruses that cause the two diseases—SARS-CoV (the SARS virus) and SARS-CoV-2 (the COVID-19 virus)—sound similar. However, there are some key differences between the two coronavirus diseases. A notable difference between the two diseases is that COVID-19 has infected many more people than SARS.
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.

All coronaviruses have a similar structure. They are also 'enveloped' viruses, which means they are able to stick to surfaces, but are also able to be killed with disinfectants. The novel virus that causes COVID-19 is one-nine hundredth of a width of a piece of hair."
The Centers for Diseases Control and Prevention (CDC) and the World Health Organization recommend (1,2) using a bleach solution as one way to disinfect areas contaminated with the novel coronavirus. There are other cleaning solutions available, including sprays, wipes, and more that can help disinfect areas exposed to the novel coronavirus.
We do not know the exact source of the current outbreak of coronavirus disease 2019 (COVID-19), but we know that it originally came from an animal, likely a bat. At this time, there is no evidence that animals play a significant role in spreading SARS-CoV-2, the virus that causes COVID-19, to people.
How did coronavirus get transferred from animals to humans? Scientists may have an answer. Experts insist there is evidence the virus was not man-made.
That is not surprising: The spikes on the surface of coronaviruses give this virus family its name – corona, which is Latin for “crown,” and most any coronavirus will have a crown-like appearance. These images are available to the public for free high-resolution download on the NIAID Flickr page.

Feline Coronavirus (FCoV) is a common viral infection in cats. It generally causes asymptomatic infection, but can cause mild diarrhea. As yet poorly understood changes in the virus can give rise to mutants that lead to the development of feline infectious peritonitis (FIP).

Influenza (flu) and COVID-19 are both contagious respiratory illnesses, but they are caused by different viruses. COVID-19 is caused by infection with a coronavirus first identified in 2019, and flu is caused by infection with influenza viruses. COVID-19 seems to spread more easily than flu.
