Myth
Only cruise passengers get norovirus.
Reality
Schools, hospitals and homes see far more cases. Ships are amplifiers.
Darker cells mean a higher score for this topic on that metric.

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.
Blame the ship and you miss the school gym. Blame the victim and you miss the dose math.
Myths are not a rehydration prescription.
Myths vs evidence
Myth
Alcohol gel is enough.
Reality
Soap and water are preferred for this virus. Gels can fail.
Myth
If the room looks clean it is safe.
Reality
Invisible particles can linger after a visible tidy-up, especially after vomit.
Myth
You cannot get it twice.
Reality
Short, genotype-specific immunity means new winters can repeat the story.
Myth
Antibiotics shorten norovirus.
Reality
It is a virus. Antibacterials do not hit it and spend the resistance budget.
Myth
This page can tell you exactly how to disinfect a ward.
Reality
Educational only. Hospitals use staff protocols. Household talk stays at soap, stay-home and ordinary bleach leaflets.
A few particles can start a school or cruise outbreak. Soap, bleach on surfaces and staying home are the public-health lesson — not a culturing kit.

A winter respiratory virus of drift and rare shift — surveillance and vaccines, not a cartoon villain.
Familiarity 93Tuberculosis
An airborne bacillus of latency and long care — programmes and air, not a drug recipe.
Familiarity 70Escherichia coli
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.
