====Hepatitis C====

Hepatitis C infections each year had been declining since the 1980s, but began to increase again in 2006.<ref>{{Cite web|url=https://www.cdc.gov/hepatitis/statistics/2013surveillance/commentary.htm|title=Commentary {{!}} U.S. 2013 Surveillance Data for Viral Hepatitis {{!}} Statistics & Surveillance &nbsp;{{!}} Division of Viral Hepatitis {{!}} CDC|website=www.cdc.gov|access-date=2016-03-09|url-status=live|archive-url=https://web.archive.org/web/20160305151134/http://www.cdc.gov/hepatitis/statistics/2013surveillance/commentary.htm|archive-date=2016-03-05}}</ref>  The data are unclear as to whether the decline can be attributed to [[needle exchange programme]]s.<ref>Wright NMJ, Millson CE, Tompkins CNE (2005).

====Alcoholic hepatitis====

Because people with alcoholic hepatitis may have no symptoms, it can be difficult to diagnose and the number of people with the disease is probably higher than many estimates.<ref>{{Cite journal|last1=Basra|first1=Sarpreet|last2=Anand|first2=Bhupinderjit S|date=2011-05-27|title=Definition, epidemiology and magnitude of alcoholic hepatitis|journal=World Journal of Hepatology|volume=3|issue=5|pages=108–113|doi=10.4254/wjh.v3.i5.108|issn=1948-5182|pmc=3124876|pmid=21731902 |doi-access=free }}</ref> Programs such as [[Alcoholics Anonymous]] have been successful in decreasing death due to [[cirrhosis]], but it is difficult to evaluate their success in decreasing the incidence of alcoholic hepatitis.<ref>{{Cite web|url=http://pubs.niaaa.nih.gov/publications/arh27-3/209-219.htm|title=The Epidemiology of Alcoholic Liver Disease|website=pubs.niaaa.nih.gov|access-date=2016-03-09|url-status=live|archive-url=https://web.archive.org/web/20160303180417/http://pubs.niaaa.nih.gov/publications/arh27-3/209-219.htm|archive-date=2016-03-03}}</ref>
