Prevalence and Incidence of Vibrio parahaemolyticus
| 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. For more information see about prevalence and incidence statistics. |
Incidence (annual) of Vibrio parahaemolyticus: 0.25 per 100,000 (DBMD 1997)
Incidence Rate: approx 1 in 400,000 or 0.00% or 680 people in USA [about data]
Prevalance of Vibrio parahaemolyticus: 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.1
Incidence of Vibrio parahaemolyticus: In 1997, the incidence of diagnosed V. parahaemolyticus infection in Food Net sites was .25/100,000.2
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.
