<p>Data is not collected on new cases of liver disease. Liver disease covers many
individual diseases caused by different factors, such as alcoholic liver disease,
fatty liver disease as well as hepatitis related diseases. The identification of new
cases will take place in different settings, from general practice to hospital outpatients.</p><p>
</p><p>The nearest proxy measure that we have is hospital admissions. However, hospital
admissions only reflect the most serious cases when people are admitted to hospital.
The number of hospital admissions for liver disease rose from 35,581 in 2001-02 to
57,682 in 2011-12, an increase of 62%.</p><p> </p><p>Hepatitis A, B, C and E are viruses
that affect the liver. Where tests can differentiate acute from chronic infections,
data is presented as newly acquired infections and where not, data is presented as
newly diagnosed cases. Hepatitis surveillance data for 2013 will be available in August
2014.</p><p> </p><p>Cases of confirmed newly acquired hepatitis A virus infection
are reported by laboratories to Public Health England.</p><p> </p><p>Table 1: Hepatitis

</p><p><em>Note: </em></p><p>At present serological tests are not able to differentiate
between acute and chronic cases of hepatitis C infection. Therefore, laboratory reports
of hepatitis C contain both recently acquired infections and past infections. For
this reason the data represent newly diagnosed cases of hepatitis C as opposed to
newly acquired infections.</p><p> </p><p>Laboratory reports of confirmed cases of
hepatitis E are reported to Public Health England. Surveillance began in 2003.</p><p>
