Prevalence and Incidence of Hepatitis B


advertisement

About prevalence and incidence statistics: The term 'prevalence' of Hepatitis B usually refers to the estimated population of people who are managing Hepatitis B at any given time. The term 'incidence' of Hepatitis B refers to the annual diagnosis rate, or the number of new cases of Hepatitis B 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.

Prevalance of Hepatitis B: estimated 1.5 million HBV carriers in the U.S. (NWHIC); 417,000 people currently infected (CDC 2001)
Prevalance Rate: approx 1 in 181 or 0.55% or 1.5 million people in USA [about data]
Incidence (annual) of Hepatitis B: 200,000 to 300,000 new cases in the USA 1990 (Digestive diseases in the United States: Epidemiology and Impact – NIH Publication No. 94-1447, NIDDK, 1994)
Incidence Rate: approx 1 in 1,359 or 0.07% or 200,000 people in USA [about data]
Lifetime risk for Hepatitis B: 4% of population in the USA have history of HepB disease 1990 (Digestive diseases in the United States: Epidemiology and Impact – NIH Publication No. 94-1447, NIDDK, 1994)
Worldwide prevalence of Hepatitis B:360 million people worldwide for Hepatitis B (Blood Safety Surveillance and Health Care Acquired Infections Division, Health Canada)
Prevalance of Hepatitis B: Approximately 750,000 people in the United States are living with sexually acquired hepatitis B infection.1 ... 4 percent of U.S. population that have any history of disease (1990)2 ... There are an estimated 1.5 million HBV carriers in the U.S. and 300 million carriers worldwide.3
Incidence of Hepatitis B: An estimated 77,000 cases of sexually transmitted hepatitis B infection occur annually in the United States.1 ... 200,000 to 300,000 new cases (1990)2
