Trend of Malaria Test Positivity Rate Among Pregnant Women, Savannah Region, Ghana, 2018 – 2022

Background Malaria in a pregnant woman (MiP) remains a serious public health problem due to its negative effects on maternal health, pregnancy outcomes and the cost of healthcare delivery. There have been some successes achieved in the control of malaria globally. However, little is known about the progress made in the control of malaria in pregnancy in the Savannah region. We described the trend of the MiP test positivity rate in the Savannah region of Ghana from 2018 to 2022. Methods The study was a retrospective descriptive cross-sectional study using data from 2018 to 2022. Data on malaria in pregnancy in the Savannah region was extracted from the DHIMS 2 database and transferred into Microsoft Excel version 19. Descriptive statistical analyses were done. Results were summarised into frequencies and percentages and presented in tables, graphs and maps. Results Cumulatively over the study period, the MiP testing rate was 90.8% (46,734/51,479) and 54.5% (25,463/46,734) of pregnant women tested positive. Majority (68.0%) of MiP cases in the region were mothers aged 20–34 years, however, the MiP test positivity rate was highest among mothers aged below 20 years. Bole District had the highest MiP test positivity rate of 70.1% (10,315/14723) and accounted for 40.5% (10,315/25,463) of all MiP cases. There was a decline in the MiP test positivity rate from 60.4–51.6% between 2018 to 2022. Conclusion The MiP test positivity rate in the Savannah region is high with disparities among Districts, however, there is an apparent decline over the study period. There is the need to strengthen existing malaria prevention interventions in pregnancy such as the use of SP for IPTp and ITNs to prevent negative maternal and fetal birth outcomes. Public health education programmes could improve the uptake and utilisation of ITNs. Further research should be conducted to unravel the reasons for the disproportionately high MiP test positivity rate in the Bole District to enable preventive measures to be instituted.
