Dutch clubbers take part in a big Covid-survey party

A total of 1,300 people took part in a party on Saturday in Amsterdam's Ziggo Dome, which also acted as a research project, the Chronicle Herald reports. Dutch DJs Sam Feldt, Sunnery James & Ryan Marciano were playing as the party-goers were followed in all their movements and contacts through a tag they were made to wear, as part of an effort to examine how events may safely be opened up for the public again. The event was part of a series of government-backed tests that also include a business conference, two football matches and a comedy show – all of which have different rules for different groups, to see what works best.
