Malaria Data Analysis Using Routine Surveillance Data, Sunyani Municipality, Ghana, 2020

Abstract Introduction: Malaria is endemic in Ghana, accounting for about 40% of all OPD diagnosis. Data on malaria is routinely collected as part of the IDSR monthly reporting forms. Sunyani municipality recorded 56,540 malaria cases in 2016 with about 35% of the cases occurring in children under five years of age. We analyzed malaria surveillance data to identify the distribution of malaria cases by person, place and time and determine the timeliness and completeness of malaria report submission in the municipality.Methods: We analyzed malaria surveillance data in Sunyani municipality reported between 2015 and 2019 from the District Health Management Information System II. We calculated morbidity and mortality rates of cases by person and estimated proportion of cases by sub-districts. We performed trend analysis and calculated disease threshold levels. We presented the findings using tables and figures.Results: Of 639,361 malaria cases suspected, 93.5% (597,512/639,361) were tested, of which 49.4% (295,458/597,512) was positive. Females accounted for 55.7% (164,436/295,458) of the morbidity. Children <5 years recorded the highest proportion, 29.9% (88,135/295,458) of cases in the municipality. The case fatality rate was 3.7% (18/484) and 1.4% (7/484) for persons under age five and over age five, respectively. Abesim (6,276.03 per 10,000) recorded the highest number of cases, and the least cases were in New Dormaa (1,890.97 per 10,000). The majority of malaria cases were in May and October of each year. Antwi-krom recorded the highest rates of completeness and timeliness of 41.9% and 40.0% respectively. Conclusion: More females were diagnosed with malaria and children <5 years recorded the highest proportion of cases in the municipality. Abesim recorded the highest proportion of malaria cases during the period. High patterns of malaria transmissions occurred during months of high rainfalls. None of the sub-districts met the WHO target for timeliness and completeness of report submission. The NMCP should consider interventions such as SMC among children under five, in the Sunyani municipality.
