The Netherlands has tried to adopt an intelligent lockdown", but the infection is spreading rapidly and it has one of the world's highest mortality rates from the pandemic. Having shunned the stricter measures of neighbouring states the government has pursued an "intelligent" or "targeted" lockdown. It wants to cushion the social, economic and psychological costs of social isolation and make the eventual return to normality more manageable. [The] local florist, ironmonger, delicatessen, bakery and toy store are still serving customers. Posters on the door and sticky tape on the floor encourage people to give each other space. Only those businesses that require touching, like hairdressers, beauticians and red light brothels, have been forced to cease trading. Schools, nurseries and universities are closed. Bars, restaurants and cannabis cafes are shut, although they seem to be doing a roaring trade in takeaways. "We think we're cool-headed," explained Dr Louise van Schaik of the Clingendael Institute of International Relations. "We don't want to overreact, to lock up everybody in their houses." People have been advised to stay at home, but you can go out if you are unable to work from home ... as long as you maintain 1.5m (5ft) social distance. It helps that the Dutch appear to be broadly compliant. One survey suggested 99% of people kept their distance. Dutch public health agency RIVM has launched a study to see how far antibodies created when people are exposed remain effective in preventing re-infection. "It's kind of like creating your own internal vaccine, by being exposed to it and then letting your body generate those antibodies naturally," Prof Aura Timen from the RIVM told the BBC.
