What the picker changes
  • Top topics digest — the cards score the selected period against the prior 4 weeks.
  • 12-week heatmap & outlet matrix — show the 12 weeks ending at the selected week (they slide back with the picker, they aren’t a fixed snapshot).
  • Per-topic volume / alias drift — same 12-week trailing window, anchored on the selected period.
  • Coverage gap quadrant — scores the selected period against the 12 weeks before it (not including it).
  • Anomaly cards — only show alerts the detector fired during the selected period. Quiet weeks legitimately show none.
What stays as-is
  • Outlet orientation strip / lean colours — context-only, drawn from the last 12 weeks of activity regardless.
  • Co-occurrence graph — recent-activity anchored, not picker-driven.
  • Source & topic profiles — all-time data for the topic; the picker doesn’t affect them.
Rolling 7 days is a sliding live window for “current vibes”; switch to Weekly to compare specific weeks side-by-side.

  • You may have heard there is a new virus making headlines. Three people have died, and several others have fallen ill after an outbreak of Hantavirus on a cruise ship. Governments and health agencies around the world are coordinating a mass evacuation of passengers, working together to get people home while at the same time trying to prevent any further spread. So should we be worried here in New Zealand? What are the real world risks for most people? What are the warning signs? And what does this response tell us about how authorities handle a serious disease threat? Have we gotten any better at it? Today on the front page, Massey University infectious diseases expert, Professor David Heyman is with us to unpack the outbreak, the evacuation, and whether this is really an unprecedented public health operation.
