The British man caught the virus as he attended a conference in Singapore and then passed it on to several fellow Brits while on holiday in the French Alps, before finally being diagnosed back in the UK.
Of those infected by the man, five have been hospitalised in France, five in Britain and one other man on the Spanish island of Mallorca.
How did he pass on the new coronavirus so rapidly in so many different places?
The man attended a business conference in Singapore in January where. Of the more than 100 people taking part at least one was a Chinese national from Hubei province, the epicentre of the epidemic that has now left more than 900 dead.
The man then travelled on to France on holiday in a ski resort of Contamines-Montjoie in the Alps, together with a group of British citizens who stayed in the same chalet.
After his return to the south of England, the man was struck by a fever. He went to a medical centre in the southeastern town of Brighton where he was diagnosed with the coronavirus.
On February 6th he was transferred to the infectious diseases unit at the hospital of St Thomas in London.
Five other people who had contact with him at the French ski chalet were then confirmed by the British health authorities to be infected with the virus.

Health Minister Agnès Buzyn said on February 8th that five British nationals, including a child, who stayed at the chalet with the man had tested positive for the novel coronavirus.
Six other Britons staying in the same chalet were also hospitalised for observation.
“They show no serious signs” of those infected having any threat to their lives, added Buzyn.

Business owners in the Contamines-Montjoie resort wanted to avoid exaggerating the threat as French families prepared to descend on the area for the half-term ski holidays.
Three schools attended by one of the British infected – the child aged nine – were closed and 100 have been people tested. All the results have been negative so far.
Experts said that the speed of the transmission showed the potential for the novel coronavirus to become a global pandemic.
“The recent report of transmission to British nationals in France are a worrying but perhaps not unexpected development,” said Paul Hunter, Professor in Medicine, University of East Anglia.
“This reinforces the fact that transmission is no longer restricted to China. It is still too early to know when and if the epidemic will become pandemic and whether we will see start to see sustained person to person transmission in Europe.”
The novel coronavirus has overtaken the number of global fatalities in the 2002-03 SARS epidemic. On Monday the death toll passed 1,000 in mainland China. The Chinese government put the nationwide toll at 1,016 on Monday – up 108 from the day before.
The World Health Organisation said this weekend that the outbreak appeared to be stabilising.
