I was reading yesterday about the origin of the major outbreak in Munich,. It began when a senior employee in Wuhan travelled to the head office of Webasto (car components). She spent several days in seminars, in contact with the German management
By the time it was apparent, the infection was right through the business - one person got infected when they passed the salt in the canteen.
If she had joined the seminars by VC it might not have been as satisfactory but it would have saved hundreds of millions of euros and many lives.
There's a slogan in Hong Kong which says Things can't return to normal. Normal was the problem.
