About contagion: Contagion and contagiousness refers to how easily the spread of Food poisoning is possible from one person to another. Other words for contagion include "infection", "infectiousness", "transmission" or "transmissability". Contagiousness has nothing to do with genetics or inheriting diseases from parents. For an overview of contagion, see Introduction to Contagion.

Contagion summary: Unlike many foodborne pathogens that have animal reservoirs, it is believed that Norwalk-like viruses spread primarily from one infected person to another.  Infected kitchen workers can contaminate a salad or sandwich as they prepare it, if they have the virus on their hands.  Infected fishermen have contaminated oysters as they harvested them.  1

Ingestion of contaminated food, with or without subsequent spread from person to person by the fecal-oral route.2
