Rationale

This metric shows the number of people living with chronic hepatitis B virus in England at a single point in time. It describes the total burden of disease and identifies groups of people who are disproportionately affected. Understanding the disease burden helps to make informed decisions about the need for testing, treatment and preventative measures like vaccination.

Methodology

UKHSA uses a published model that employs laboratory surveillance data and population estimates from the 2021 census. HBV laboratory test data from pregnant women tested as part of antenatal screening are broken down by age and ethnicity, providing baseline estimates of prevalence. This data is assumed to be representative of women of childbearing age given the high uptake of antenatal screening. HBV laboratory test data from non-antenatal settings by sex, ethnic group and age group provides information on differences in prevalence, represented by the ratio of HBV positivity, applied to antenatal screening estimates. Population estimates by age, sex and ethnicity for England are used to extrapolate the number of people living with chronic hepatitis B.

Caveats

Estimates are based on surveillance models and may change with the availability of data.
