Super spreaders

Coronavirus cases traced to a business meeting in Singapore have reached three European countries after causing infections in Asia, raising fears of a so-called super-spreader event.

A cluster of cases of the virus in France, Spain and the U.K. confirmed in the past day all appear to have links to a French ski resort where the infected people had contact with a British man who had just returned from the conference. The meeting was organized by an unidentified company in January and was attended by more than 90 foreigners.
