The facts and what you need to know about coronavirus.
The death toll in China has reached 81
There are currently 2908 people diagnosed with coronavirus around the world.
Confirmed cases have been identified in China, Vietnam, Japan, Thailand, Singapore, South Korea, Malaysia, Nepal, Macau, France, Canada and the US.
The World is getting to know Wuhan as the city where the coronavirus outbreak began.
Early cases of the virus were linked to a market in Wuhan that sells animals as well as seafood. Coronaviruses are a group of viruses that are transferred from animals to humans.
Temperature checks have been brought in to test people at airports, train stations, coach stations and ports.
A 2002-2003 outbreak of severe acute respiratory syndrome (Sars), the deadly virus that killed more than 800 people, was passed to humans via contact with civet cats.
230 of the world's 500 biggest companies (as measured by the Fortune Global list) have a presence in Wuhan with people travelling to and from the city on a daily basis, although the coronavirus originated in a local seafood market, the flow of people in and out of Wuhan has ensured its spread.
Wuhan's status as one of the biggest - and most connected - places in the world means international cases will almost certainly continue to emerge.
The symptoms of coronavirus
a high temperature
a cough and or sore throat
- think have you travelled in the last two weeks or have you been in contact with someone who has travelled to a high risk area in the last two weeks?
The virus is spread in the same way as the common cold droplets when a person coughs or sneezes - it can also be spread by contact, a handshake or when someone who has the virus touches a surface such as a hand rail or door knob.
Hand hygiene is the first way to protect yourself
try not to touch surfaces in public places
don't share snacks where other people have put their fingers
avoid shaking hands or kissing other people
wash your hands regularly and use the 'catch it, bin it, kill it' mantra for coughs and sneezes
