What is an 'intelligent lockdown'?
The Dutch are among the few who began by openly embracing the contentious idea of group or herd immunity.
It's an approach characterised by one Dutch global health expert as cold and calculated.
Cities may be quieter, but children still clamber on climbing frames and teenagers cycle side-by-side.
How Dutch went beyond UK on herd immunity When the UK's chief scientific adviser revealed a plan to develop a broad immunity across the population, within days researchers revealed it could claim a quarter of a million lives, and the UK changed course.
Allowing a deadly virus to spread through society to create a level of immunity implicitly means accepting people will die.
In a televised speech to the nation on 16 March, .
"We can delay the spread of the virus and at the same time build up population immunity in a controlled manner," he said.
Dutch government The bigger the group that acquires immunity, the smaller the chance that the virus can make the leap to vulnerable older people or people with underlying health issues Mark Rutte Dutch Prime Minister, 16 March 2020 "We have to realise that it can take months or even longer to build up group immunity and during that time we need to shield people at greater risk as much as possible."
For Dr Van de Pas it's a cold and calculated Dutch approach, that can perhaps only work in an individualistic society used to a non-interventionist medical culture, from cradle to grave.
While herd immunity, modified as it is, may eventually dampen the effects of the epidemic, it has to be accepted by a substantial part of the population.
The worry is that the Dutch approach may be based more on aspiration than actual intelligence, and that the Netherlands' "intelligent lockdown" does not make the country immune.
