It's a focussed effort to contain/eradicate the virus. At current levels, it's already possible to extensively investigate every single case and trace & isolate contacts. That should allow for continued reduction with far lower restrictions on daily life compared to the blanket measures of the last few weeks. And while specifically protecting nursing homes and the elderly is obviously being attempted, that's just far harder than one might think: nursing homes have a lot of employees, almost all of which are rather young. While some contacts can be minimised by, for example, switching to external catering, the need for care, cleaning, and medical treatments are rather inflexible.
