Prevalence and Incidence of Botulism food poisoning


About prevalence and incidence statistics: The term 'prevalence' of Botulism food poisoning usually refers to the estimated population of people who are managing Botulism food poisoning at any given time. The term 'incidence' of Botulism food poisoning refers to the annual diagnosis rate, or the number of new cases of Botulism food poisoning 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 Botulism food poisoning: 154 annual cases notified in USA 1999 including 23 foodborne, 92 infant, and 39 other (MMWR 1999)

Prevalance of Botulism food poisoning: In the United States an average of 110 cases of botulism are reported each year. Of these, approximately 25% are foodborne, 72% are infant botulism, and the rest are wound botulism. Outbreaks of foodborne botulism involving two or more persons occur most years and usually caused by eating contaminated home-canned foods. The number of cases of foodborne and infant botulism has changed little in recent years, but wound botulism has increased because of the use of black-tar heroin, especially in California. 1 ... In 1999, 174 cases of botulism were reported to the CDC. Of these, 26 were foodborne, 107 were infant botulism, and 41 were cases of wound botulism.2
