(b) Chronic Hepatitis B
Data on chronic hepatitis B are not collected.
Data are collected on laboratory reports of acute Hepatitis B. Surveillance of the incidence of acute infection is used to monitor trends, to evaluate the Hepatitis B immunisation programme and to inform the development of national and local control policies.
(c) Hepatitis C

(d) Hepatitis D

(e) Hepatitis E
Information is available from 2003 to 2006
Number of reports 2003 125 2004 150 2005 329 2006 292 Source: Health Protection Agency
(f) Hepatitis F
Hepatitis F is a hypothetical hepatitis virus. Several hepatitis F virus candidates emerged in the 1990s. Further investigations failed to confirm the existence of the virus, and it was delisted as a cause of infectious hepatitis.

(h) Hepatitis H
There is currently no virus designated as hepatitis H.
