Summary

Topic
Hepatitis-B
Category
API name
hepatitis-b_cases_acuteIncidenceByYear

Rationale

This metric shows the number of acute hepatitis B diagnoses in England. This metric helps to monitor transmission of hepatitis B in the population.

Definition

The number of new acute hepatitis B diagnoses reported in England during the year.

Methodology

Data come from national laboratory surveillance. Only new cases confirmed during the reporting year are included. Numbers are compared over time to monitor trends.

Caveats

Some cases may not be diagnosed or reported. More testing can increase reported numbers without a real rise in infections. Changes in testing or reporting can affect trends.
