This table provides metadata for the actual indicator available from Kenya statistics closest to the corresponding global SDG indicator. Please note that even when the global SDG indicator is fully available from Kenyan statistics, this table should be consulted for information on national methodology and other Kenyan-specific metadata information.

| Definition and concepts |
Hepatitis B is a viral infection that attacks the liver and can cause both acute and chronic disease. This indicator is measured indirectly through the proportion of children 5 years of age who have developed chronic HBV infection (i.e. the proportion that tests positive for a marker of infection called hepatitis B surface antigen [HBsAg]).1 Hepatitis B surface antigen: a protein from the virus’s coat. A positive test for HBsAg indicates active HBV infection. The immune response to HBsAg provides the basis for immunity against HBV, and HBsAg is the main component of HepB. |
| Unit of measure |
Number of cases per 100,000 population |
| Classifications |
Hepatitis B is defined in terms of the International Classification of Diseases, Tenth Revision (ICD-10) |
| Data sources |
Health Information Management System |
| Data collection method |
Record of children testing positive for Hepatitis B |
| Data collection calendar |

| Data release calendar |

| Data providers |

Ministry of Health and Kenya National Bureau of Statistics |
| Institutional mandate |
Ministry of Health is responsible for overseeing preventive and promotive health services in the country Kenya National Bureau of Statistics is the principal government agency for collection, compilation, analysis and dissemination of statistical information. It is also the custodian of official statistics. |
| Rationale |
Hepatitis B is a viral infection that affects the liver and can lead to serious health complications, including liver cirrhosis and liver cancer. By monitoring the incidence of acute Hepatitis B cases, health authorities can assess the effectiveness of prevention measures (such as vaccination programs) and early detection efforts. |
| Comment and limitations |
Comments Data presents facility-based disease incidence., not chronic Hepatitis B infections. The quality and completeness of the data on hepatitis B incidence may vary across countries and regions, depending on the availability and accessibility of diagnostic tests, surveillance systems, and reporting mechanisms. The data may not capture the true burden of hepatitis B infection, as many cases may be asymptomatic or undiagnosed, especially in low-resource settings. The data may be affected by changes in the definitions, classifications, or methodologies used to measure hepatitis B incidence over time and across countries, which may affect the comparability and consistency of the data. |
| Method of computation |
The indicator is calculated by dividing the number of new cases of Hepatitis B infection in a given year by the total population and multiplying by 100,000. |
| Validation |
Data on Hepatitis B is validated annually by the Technical Working Committee on Health and Vital Statistics |
| Methods and guidance available to countries for the compilation of the data at the national level |
Some of the methods and guidance available to countries for the compilation of the data at the national level for indicator 3.3.4 are: The WHO Global Hepatitis Report 2023, which provides the latest estimates of hepatitis B incidence and prevalence, as well as the data sources and methods used to produce them. The WHO Guidelines for the Prevention, Care and Treatment of Persons with Chronic Hepatitis B Infection, which provide recommendations on the diagnosis, monitoring, and treatment of hepatitis B, as well as the indicators and data collection tools for measuring the impact of interventions. The UNSD SDG indicator metadata, which provide the definition, rationale, concepts, sources, and calculation methods for indicator 3.3.4, as well as the validation, disaggregation, and regional and global comparability issues. |
