Hepatitis

Volume 488: debated on Wednesday 25 February 2009

To ask the Secretary of State for Health how many (a) males and (b) females in each age group have been diagnosed with acute hepatitis (i) A, (ii) B, (iii) C, (iv) D, (v) E and (vi) G in each year since 1997. (254997)

The available information is shown in the following tables. However, data for acute hepatitis C are not available, as surveillance data collected by the Health Protection Agency (HPA) do not distinguish between current and past infections or between recently acquired and chronic infections. The HPA does not collect data on hepatitis D as hepatitis D is a defective virus that replicates only in the presence of acute or chronic hepatitis B infection. The HPA also does not routinely collect data on hepatitis G as extensive worldwide investigation has failed to identify any association between the hepatitis G virus and hepatitis and its clinical significance is unknown.

Notes:

1. Surveillance of hepatitis B is based upon reports of confirmed acute hepatitis B received from laboratories in England. Since 2003, the completeness of data on whether hepatitis B infections are acute or chronic infection has decreased and therefore figures since then are not reliable. The HPA is working to improve the quality of information on acute hepatitis B reporting and provisional data for 2007 should be available later this year.

2. Where fewer than five cases were reported for a category, the table indicates the number of cases reported as <5 rather than the actual number in order to reduce the risk of deductive disclosure of an individual’s identity.

1. Where fewer than five cases were reported for a category, the table indicates the number of cases reported as <5 rather than the actual number in order to reduce the risk of deductive disclosure of an individual’s identity.

2. Most cases of hepatitis E are associated with travel outside of the United Kingdom.
