This table provides metadata for the actual indicator available from Ghana statistics closest to the corresponding global SDG indicator. Please note that even when the global SDG indicator is fully available from Ghanaian statistics, this table should be consulted for information on national methodology and other Ghanaian-specific metadata information.
|Indicator description||Incidence of malaria is the number of new cases of malaria in a year per 1,000 population. To measure trends in malaria morbidity and to identify locations where the risk of disease is highest. With this information, programmes can respond to unusual trends, such as epidemics, and direct resources to the populations most in need. This data also serves to inform global resource allocation for malaria such as when defining eligibility criteria for Global Fund finance.|
|Unit of measurement||per 1,000 population|
|Definitions||Case of malaria is defined as the occurrence of malaria infection in a person whom the presence of malaria parasites in the blood has been confirmed by a diagnostic test. The population considered is the population at risk of the disease.|
|Calculations||Complete data on malaria cases reported through surveillance systems are the best source of data but are rarely available for large populations. Reported data on malaria cases generally need to be corrected for extent of health service use, incompleteness of reporting and lack of case confirmation. In high transmission areas with limited health service data but with good data on parasite prevalence the number of cases can be estimated from parasite prevalence. The denominator is estimated, using risk mapping and population data.|
