Facts About Hepatitis A and C: CDC-OC (Excerpt)

Estimated 35,000­180,000 total infections/yearly in United States; 3,000­54,000 (30%) symptomatic infections/yearly; 8,000­10,000 deaths annually (Source: excerpt from Facts About Hepatitis A and C: CDC-OC)

Facts About Hepatitis C: CDC-OC (Excerpt)

During the 1980s, an estimated 230,000 new HCV infections occurred each year. Since then, the annual number of new infections has declined by >80% to an estimated 36,000 in 1996. Most of this decline was due to a decrease in cases among injection drug users. (Source: excerpt from Facts About Hepatitis C: CDC-OC)

    About prevalence and incidence statistics:

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