Epidemiology
Hepatitis C infects an estimated 170 million people worldwide and 4 million in the United States. There are about 35,000 to 185,000 new cases a year in the United States. Co-infection with HIV is common and rates among HIV positive populations are higher. 10,000-20,000 deaths a year in the United States are from HCV; expectations are that this mortality rate will increase, as those who were infected by transfusion before HCV testing become apparent. A survey conducted in California showed prevalence of up to 34% among prison inmates;[1] 82% of subjects diagnosed with hepatitis C have previously been in jail,[2] and transmission while in prison is well described.[3]
Egypt has the highest seroprevalence for HCV, up to 20% in some areas. There is a hypothesis that the high prevalence is linked to a now-discontinued mass-treatment campaign for schistosomiasis, which is endemic in that country.[4]
In 2007, there were an estimated 17,000 new Hepatitis C virus infections in the United States. However, the official number of reported Hepatitis C cases is much lower. Many people who are infected never have symptoms and therefore never come to the attention of medical or public health officials.[5]
An estimated 3.2 million persons in the United States have chronic Hepatitis C virus infection. Most people do not know they are infected because they don’t look or feel sick.<ref>CDC<ref>
Approximately 75%–85% of people who become infected with Hepatitis C virus develop chronic infection.<ref>CDC<ref>
