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 (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 are important human and animal pathogens and contain an extraordinarily long (27-31 kb) RNA genome. Its RNA synthesis involves complex mechanisms of regulation, similar to those of DNA viruses. In this treatise, mouse hepatitis virus (MHV) is used as a model for the discussion of the mechanism of viral RNA synthesis.

Coronavirus is a positive-sense single-stranded RNA virus which causes illnesses ranging from common cold and pneumonia to severe acute respiratory syndrome (SARS) and the Middle East respiratory syndrome (MERS). In contrast, influenza virus is a negative-sense, single-stranded RNA virus which causes seasonal flu epidemics each year.

Why is coronavirus different from other viruses caused?

🏥
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.

How bad is coronavirus compared to other viruses?

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.
