What Is Coronaviruses And Common Symptoms Of It

Coronaviruses are types of viruses that typically affect the respiratory tract of mammals, including humans. They are associated with the common cold, pneumonia, and severe acute respiratory syndrome (SARS) and can also affect the gut.

A coronavirus was first isolated in 1937 from an infectious bronchitis virus in birds that has the ability to seriously devastate poultry stocks.

These viruses are responsible for between 15 and 30 percent of common colds.

Over the last 70 years, scientists have found that coronaviruses can infect mice, rats, dogs, cats, turkeys, horses, pigs, and cattle. Human coronaviruses (HCoV) were first identified in the 1960s in the noses of patients with the common cold. Two human coronaviruses are responsible for a large proportion of common colds OC43 and 229E.

Coronaviruses were given their name based on the crown-like projections on their surfaces. "Corona" in Latin means "halo" or "crown."

Among humans, infection most often occurs during the winter months as well as early spring. It is not uncommon for a person to become ill with a cold that is caused by a coronavirus and then catch it again about four months later. These viruses are transmitted between animals and people. SARS, for instance, was believed to have been transmitted from civet cats to humans while MERS travelled from a type of camel to humans.

Several known coronaviruses are circulating in animals that have not yet infected humans.

The name coronavirus comes from the Latin word corona, meaning crown or halo. Under an electron microscope, the image of the virus is reminiscent of a solar corona.

A novel coronavirus, identified by Chinese authorities on January 7 and currently named 2019-nCoV, is a new strain that had not been previously identified in humans.

Little is known about it, although human-to-human transmission has been confirmed.

Symptoms of Coronavirus

* According to the WHO, signs of infection include respiratory symptoms, fever, cough, shortness of breath and breathing difficulties.

* In more severe cases, it can lead to pneumonia, severe acute respiratory syndrome, kidney failure and even death.

* Reports say the incubation period of the coronavirus remains unknown, but other sources say it could be between 10 to 14 days
