Quick answers
Where should I start with Norovirus?
Read Identity → How they live → Body & health, then use compare rails.
Is this page advice for Norovirus?
Public-health education — not a care plan, prescription, or outbreak briefing.
What does the local lens add?
It names everyday desks for Encounters before English norms look universal.
Are the scores a ranking of Norovirus?
No — editorial 0–100 browsing aids inside this atlas only.
How do I compare Norovirus to neighbours?
Use related cards and best-of / quiz rails after the first three chapters.
Which chapter is densest?
How they live and Body & health carry mechanisms; skim Identity first.
Closed rooms make arithmetic visible. The same virus is quieter in a well-ventilated house with one careful sick person.
Hospitals fear ward closures. Food businesses fear an ill cook. Those are occupational interfaces.
Body interfaces
Cruise cabin
Shared corridors and buffets turn a low dose into a visible epidemic curve.
Hospital ward
Frail patients and shared toilets make norovirus a closure-level event.
Oyster harvest
Filter feeders can concentrate virus from sewage-tinged water.
Catering hands
Ready-to-eat assembly is a classic point of control when staff are ill.
Home bathroom
One household can contain a chain with soap, isolation of the sick room, and patience.
Dehydration care is clinical when drinking fails, especially in the very young and old.
