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.
Identity is a non-enveloped RNA virus that laughs at some alcohol gels and loves shared indoor vomit events.
Many genotypes mean last year's memory may not cover this year's file.
Traits
Low dose
A conceptually tiny number of particles can start illness.
Many genotypes
GII.4 and others take turns. Short immunity follows.
Vomit aerosol
Projectile vomiting can seed a room beyond the visible mess.
Food handler
Ready-to-eat food touched by an ill person is a classic vehicle.
Not influenza
Stomach flu is a nickname. The virus is not a flu virus.
A cruise headline is an amplifier story, not a species origin story.

Usually a gut resident; a minority of STEC pathotypes drive foodborne headlines.
Familiarity 82Staphylococcus aureus
A common skin neighbor and a resistance story called MRSA — not scare porn.
Familiarity 78Helicobacter pylori
A gastric spiral that rewrote the ulcer textbook — Nobel 2005, Korea's high historic prevalence, no recipes.
