Table
Indicator name:
Hepatitis - Prevalence of chronic hepatitis (HBV and HCV) among the general population
Short name:
Chronic hepatitis prevalence
Data type:
Percent
Indicator Id:
3523
Topic:
Hepatitis, burden of diseases
Rationale:
This indicator measures progress towards reduction of chronic HBV and HCV infections as part of the GHSS 2030 elimination targets.
By analyzing the prevalence of chronic hepatitis B and C, programmes can understand the burden and plan testing, care and treatment accordingly.
Definition:
Percent of total population who are HBsAg positive
Percent of the total population who are anti-HCV(+) or HCV RNA positive
Disaggregation:
By country and WHO region
Method of measurement
Extrapolate from recent biomarker surveys.. Estimates may be modelled from older biomarker surveys and/or contemporaneous surveys in various populations of interest. Modelling can be used alongside available programme data, such as routine surveillance testing data, taking note of the methodological limitations and representativeness of the population. Such models need to consider relevant input parameters such as number of people treated over time, vaccination coverage, HBV infection incidence and deaths (liver-related deaths and background deaths in the general population).
M&E Framework:
Context and needs
Method of estimation:
Modelling using the PRoGReSs (for HBV) and Markov (disease progression) model for HCV. Estimates of HBV and HCV prevalence are produced through a consultative and analytical process led by WHO
Method of estimation of global and regional aggregates:
Estimates are also produced at global level and for WHO regions
Preferred data sources:
National population-based surveys in high-burden epidemics, otherwise modelled estimates
Unit of Measure:
Percent
Unit Multiplier:
Chronic hepatitis prevalence
Expected frequency of data dissemination:
Every two years
Expected frequency of data collection:
Annual
