Prevalance of Vibrio parahaemolyticus:
Major outbreaks have occurred in the U.S. during the warmer months of the year. Sporadic cases occur along all coasts of the U.S.

Nationwide, an average of 190 culture-confirmed
cases, 30 hospitalizations, and 1-3 deaths are reported each
year. However, it is estimated that there are truly as many
as 3000 cases (most not culture confirmed), 40 hospitalizations
and 7 deaths. (Source: excerpt from Vibrio parahaemolyticus: DBMD)
Prevelance of Vibrio parahaemolyticus discussion:
In Asia, V. parahaemolyticus is a common
cause of foodborne disease. In the United States, it is less
commonly recognized as a cause of illness, partly because clinical
laboratories rarely use the selective medium that is necessary
to identify this organism. Not all states require that V.
parahemolyticus infections be reported to the state health
department, but CDC collaborates with the Gulf Coast states
of Alabama, Florida, Louisiana, and Texas to monitor the number
of cases of Vibrio infection in this region. From those states,
about 30-40 cases of V. parahaemolyticus infections are
reported each year. The Foodborne Diseases Active Surveillance
Network, Food Net, also tracks V. parahaemolyticus in
regions outside the Gulf Coast. In 1997, the incidence of diagnosed
V. parahaemolyticus infection in Food Net sites was .25/100,000.

Outbreaks of Vibrio parahaemolyticus:
Selected Outbreaks:: MMWR 48(03):1999 During July-September 1998, an outbreak of Vibrio parahaemolyticus infections associated with consumption of oysters and clams harvested from Long Island Sound occurred among residents of Connecticut, New Jersey, and New York. This is the first reported outbreak of V. parahaemolyticus linked to consumption of shellfish harvested from New York waters.
MMWR 47(22):1998 During July-August 1997, the largest reported outbreak in North America of culture-confirmed Vibrio parahaemolyticus infections occurred. Illness in 209 persons was associated with eating raw oysters harvested from California, Oregon, and Washington in the United States and from British Columbia (BC) in Canada; one person died.

About prevalence and incidence statistics:
The term 'prevalence' of Vibrio parahaemolyticus usually refers to the estimated population
of people who are managing Vibrio parahaemolyticus at any given time.
The term 'incidence' of Vibrio parahaemolyticus refers to the annual diagnosis rate,
or the number of new cases of Vibrio parahaemolyticus diagnosed each year.
Hence, these two statistics types can differ:
a short-lived disease like flu can have high annual incidence but low prevalence,
but a life-long disease like diabetes has a low annual incidence but high prevalence.
