What is coronavirus?
In keeping with the WHO, coronaviruses are a family of viruses that cause sicknesses ranging from the frequent cold to more extreme ailments equivalent to severe acute respiratory syndrome (SARS) and the Center East respiratory syndrome (MERS).
These viruses have been originally transmitted between animals and people. SARS, for example, was transmitted from civet cats to humans while MERS moved to people from a type of camel.
Several known coronaviruses are circulating in animals that haven’t but infected humans.
The name coronavirus comes from the Latin word corona, that means crown or halo. Under an electron microscope, the image of the virus appears to be like like a solar corona.
The novel coronavirus, recognized by Chinese authorities on January 7 and since named COVID-19, is a new strain that had not been beforehand recognized in humans. Little is known about it, although human-to-human transmission has been confirmed.
What are the symptoms?
In line with the WHO, signs of infection include fever, cough, shortness of breath and breathing difficulties.
In more extreme cases, it can lead to pneumonia, multiple organ failure and even death.
Present estimates of the incubation interval — the amount of time between infection and the onset of signs — range from one to 14 days. Most infected folks show signs within 5 to six days.
Nevertheless, contaminated patients will also be asymptomatic, that means they do not display any symptoms despite having the virus of their systems.

How deadly is it?
With more than 2,004 recorded deaths, the number of fatalities from this new coronavirus has surpassed the toll of the 2002-2003 SARS outbreak, which also originated in China.
SARS killed about 9 p.c of those it contaminated — practically 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 it infected.
While the new coronavirus is more widespread in China than SARS in terms of case numbers, the mortality rate stays considerably lower at approximately 2 percent, in response to WHO.
What’s being carried out to cease it from spreading?
Scientists around the globe are racing to develop a vaccine but have warned that one is unlikely to be available for mass distribution before 2021.
Meanwhile, Chinese authorities have effectively sealed off Wuhan and positioned restrictions on travel to and from several other cities, affecting some 60 million people.
Many international airlines have cancelled flights to China. Some nations have banned Chinese nationals from getting into their territories and several other more have evacuated their citizens from Wuhan.
Where did the virus originate?
Chinese health authorities are still attempting to determine the origin of the virus, which they are saying possible got here from a seafood market in Wuhan the place wildlife was also traded illegally.
On February 7, Chinese researchers said the virus could have spread from an infected animal species to humans by way of illegally-trafficked pangolins, which are prized in Asia for food and medicine.
Is this a world emergency?
The outbreak now constitutes a world health emergency, the WHO said on January 30.
The choice to sound the highest-stage alarm was made after the first cases of human-to-human transmission outside China have been confirmed.
The worldwide health alert is a call to countries world wide to coordinate their response under the guidance of the United Nations health agency.
There have been five international health emergencies since 2005 when the declaration was formalised: swine flu in 2009, polio in 2014, Ebola in 2014, Zika in 2016 and Ebola once more in 2019.
