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. Laboratory confirmed cases of acute hepatitis E, England and Wales, 2003 - 2007 Source: HPA
