Is Vibrio parahaemolyticus Contagious?
Transmission of Vibrio parahaemolyticus from Person to Person
Vibrio parahaemolyticus is considered infectious but is not transmitted from person to person.
Generally, a disease like this is caused by an infectious agent and not spread between people.
Vibrio parahaemolyticus, although infectious, is not a genetic disease. It is not caused by a defective or abnormal gene.
Transmission of Vibrio parahaemolyticus
Transmission of Vibrio parahaemolyticus to a person can be by way of:
Infective dose -- A total dose of greater than one million organisms may cause disease; this dose may be markedly lowered by coincident consumption of antacids (or presumably by food with buffering capability).

Discussion about Contagion of Vibrio parahaemolyticus:
In 1998, a new
strain of the bacterium Vibrio
parahemolyticus contaminated oyster beds in Galveston
Bay and caused an epidemic of diarrheal illness in persons eating
the oysters raw. The affected oyster beds were near the shipping
lanes, which suggested that the bacterium arrived in the ballast
water of freighters and tankers coming into the harbor from distant
ports. (Source: excerpt from Foodborne Infections General: DBMD)
About contagion and contagiousness:
Contagion and contagiousness refers to how easily
the spread of Vibrio parahaemolyticus 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.
