Covid-19 'super-spreader' causes 300 person quarantine
Zurich is reporting its first case of a Covid-19 super-spreader with 300 people now in quarantine.
A man went to a nightclub in the city last weekend and has tested positive for the infection.
Fortunately, the club had been following the rules and had a list of customers for that night. They all must now self-isolate for the next 10 days.
The canton is warning if there are further cases of super-spreaders, clubs may get closed down once again.
