A British man who contracted the new coronavirus while attending a conference in Singapore may have led to seven other people catching the disease when he stopped off at a chalet in a French mountain village on his way home, health experts said on Sunday.
The man, Britain's third case of the virus, stayed for four days in the chalet in Les Contamines-Montjoie late last month, under the same roof as a group of British holidaymakers as well as a British family who lived in the village.
Five people from that group in the Alpine ski resort, including a child, contracted the coronavirus as a result, French officials said this weekend.
The trail does not end there, however. The disease carried by the same man may have spread elsewhere, underlining the challenges health authorities face in containing infections in an era of global air travel.
