Prevalence and Incidence of Brucellosis

About prevalence and incidence statistics: The term 'prevalence' of Brucellosis usually refers to the estimated population of people who are managing Brucellosis at any given time. The term 'incidence' of Brucellosis refers to the annual diagnosis rate, or the number of new cases of Brucellosis 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 Brucellosis: 82 annual cases notified in USA 1999 (MMWR 1999)
Incidence Rate: approx 1 in 3,317,073 or 0.00% or 82 people in USA [about data]
Prevalance of Brucellosis: Brucellosis is not very common in the United States, where100 to 200 cases occur each year. But brucellosis can be very common in countries where animal disease control programs have not reduced the amount of disease among animals. ¹ ... In the United States, < 0.5 cases per 100,000 population. Most cases are reported from California, Florida, Texas, and Virginia.²
