What is a coronavirus?
The coronavirus family causes illnesses ranging from the common cold to more severe diseases such as severe acute respiratory syndrome (SARS) and Middle East respiratory syndrome (MERS), according to the WHO.
They circulate in animals and some can be transmitted between animals and humans. Several coronaviruses are circulating in animals that have not yet infected humans.
The new coronavirus, the seventh known to affect humans, has been named COVID-19.
Common signs of infection include fever, coughing and breathing difficulties. In severe cases, it can cause pneumonia, multiple organ failure and death.
The incubation period of COVID-19 is thought to be between one and 14 days. It is contagious before symptoms appear, which is why so many people get infected.
Infected patients can be also asymptomatic, meaning they do not display any symptoms despite having the virus in their systems.
China alerted the WHO to cases of unusual pneumonia in Wuhan on December 31.
COVID-19 is thought to have originated in a seafood market where wildlife was sold illegally.
Explanation:
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 virus looks like it is surrounded by a solar corona.
The novel coronavirus, identified by Chinese authorities on January 7 and since named SARS-CoV-2, 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.
What are the symptoms?
According to the WHO, signs of infection include fever, cough, shortness of breath and breathing difficulties. Other signs include loss of taste or smell as well as muscle aches.
In more severe cases, it can lead to pneumonia, multiple organ failure and even death.
Current estimates of the incubation period – the time between infection and the onset of symptoms – range from one to 14 days. Most infected people show symptoms within five to six days.
However, infected patients can also be asymptomatic, meaning they do not display any symptoms despite having the virus in their systems.

How deadly is it?
The number of fatalities from the new coronavirus has overwhelmingly surpassed the toll of the 2002-2003 SARS outbreak, which also originated in China.
SARS killed about 9 percent of those it infected – nearly 800 people worldwide and more than 300 in China alone. MERS, which did not spread as widely, was more deadly, killing one-third of those infected.
While the new coronavirus is more widespread than SARS in terms of case numbers, the mortality rate remains considerably lower at approximately 3.4 percent, according to the WHO.
According to the Centers for Disease Control and Prevention (CDC), older people are at higher risk for severe illness from COVID-19 which may result in increased stress during a crisis.
People who have severe underlying medical conditions like heart or lung disease or diabetes also seem to be at high risk for developing more serious complications from COVID-19 illness.
Where have cases been reported?
Since March 16, more cases were registered outside mainland China than inside, marking a new milestone in the spread of the global pandemic.
The virus has spread from China all around the world, prompting the WHO to label the COVID-19 outbreak a pandemic.
Human-to-human transmissions became evident after cases were recorded with no apparent link to China.
