"Market participants in Europe have grave concerns about coronavirus as the death toll increased to 80 and more than 2,700 victims infected in China," said Ava Trade analyst Naeem Aslam.
He added: "The bottom line is that the virus has become deadly and it has caused a major panic in markets."
The outbreak of the coronavirus has led China to lock down the epicentre of the disease, Wuhan -- a city of 11 million people -- while also imposing tight travel restrictions on a number of other cities including Beijing.
