General information about coronavirus

What is coronavirus?
According to the World Health Organization (WHO), coronaviruses are a family of viruses that cause illnesses ranging from the common cold to more severe diseases such as severe acute respiratory syndrome (SARS) and the Middle East respiratory syndrome (MERS). These viruses were originally transmitted from animals to people. SARS, for instance, was transmitted from civet cats to humans while MERS moved to humans from a type of camel. 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 looks like it is surrounded by a solar corona.

Corona History
The virus was first discovered in China in 2002, causing SARS, but eventually spread to Mars in 2012 due to changes in the virus, which is now known Covid-19.

Where did the virus come from?
At the end of December, public health officials from China informed the World Health Organization that they had a problem: an unknown, new virus was causing pneumonia-like illness in the city of Wuhan. They quickly determined that it was a coronavirus and that it was rapidly spreading through and outside of Wuhan.

What are the symptoms of coronavirus?
Coronavirus symptoms can be very mild to severe and include a fever, cough and shortness of breath. Some people have no symptoms. Symptoms may appear two to 14 days after exposure.

How dangerous is this coronvirus?
World health officials said the mortality rate for COVID-19 is 3.4% globally, higher than previous estimates of about 2%. Older people and people with health conditions such as heart disease, lung disease and diabetes appear to be at higher risk for severe illness, according to the CDC. Of course, it should not be overlooked that it is difficult to estimate the mortality rate of the disease, because many non-acute cases of the disease are not reported.

How coronavirus spread or transmitted?
As per the doctors, coronavirus is transmitted through coughing and sneezing, as is the case with influenza and other respiratory viruses. It can transmit among the humans through close contact even form the range of about 3 to 6 feet.

What is the incubation period for the coronavirus?
It takes five days on average to start showing the symptoms, scientists have said, but some people will get symptoms much later than this. It takes five days on average to start showing the symptoms, scientists have said, but some people will get symptoms much later than this. The incubation period lasts up to 14 days, the World Health Organization (WHO) says. But some researchers say it may be up to 24 days. Knowing and understanding the incubation period is very important. It allows doctors and health authorities to introduce more effective ways to control the spread of the virus.

If you recover from coronavirus are you immune?
Well, it is too soon to tell. This virus has only been around since the end of December, but from experience with other viruses and coronaviruses you should have antibodies to the virus which will protect you. With Sars and other coronaviruses we tended not to see reinfection. Now there are some reports from China of people who are released from hospital subsequently testing positive but we're not sure about those tests. However, the key thing was those people were no longer infectious.

How will the coronavirus outbreak stop?
There is no vaccine for coronavirus. Therefore, the only way to prevent its transmission is early detection and treatment of the patient in quarantine. Look for people who have been in contact with the virus patients and monitor them. The next step is to set travel restrictions and prevent public gatherings.
