Myth
Only cruise passengers get norovirus.
Reality
Schools, hospitals and homes see far more cases. Ships are amplifiers.
Blame the ship and you miss the school gym. Blame the victim and you miss the dose math.

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.
