Factors associated with community engagement in areas with high and low incidence of local malaria cases in Zanzibar

Introduction: the prevalence of asymptomatic infection in the general population in Zanzibar has declined from above 25% in 2005 to less than 1% in 2010. Despite these achievements, in 2021, the number of malaria cases increased by two folds. This study aimed at understanding the levels of community engagement towards malaria elimination and factors associated with them to provide recommendations that can be used to reinforce community engagement. Methods: a descriptive cross-sectional survey was conducted using structured questionnaires to 431 randomly selected households. The interviewees were the heads of households or representative adults above 18 years. Univariate and multivariate analysis was done to determine the association between social demographic characteristics, malaria knowledge, practicing malaria prevention interventions and status of community engagement. Statistical significance test was declared at P- value <0.05. Results: of all respondents, 261 (60.6%) were not engaged in either planning or implementation of malaria interventions, of which 120 (45.9%) participants were in the high malaria transmission and 141 (54.0%) from the low malaria transmission (P=0.018). Factors significantly associated with increased odds of community engagement were the level of knowledge on malaria (P= 0.002) and factors independently associated with reduced odds of community engagement was the level of malaria burden (P= 0.01). Conclusion: level of malaria knowledge and malaria burden were associated with community engagement. There is a need to increase malaria knowledge in the community based on the existing gaps as this study suggests that having high malaria knowledge can significantly contribute to increased opportunity for community engagement.

Effectiveness of Malaria Intervention Programmes among Patent Medicine Vendors: A Systematic Review

Poor diagnosis, treatment and prevention practices had characterised Patent Medicine Vendor (PMV) activities in malaria control despite expectations on their contributions to check the menace. Interventions reversing this situation reduces disease burden and legitimise PMV inclusion in basic healthcare delivery. This study seeks to identify and review studies addressing this priority problem. Steps outlined in PRISMA guidelines were adopted to search and conduct reviews via electronic databases. Randomized trials with intervention effects on PMVs were considered and thirteen articles were ultimately reviewed and narratively evaluated. Analysis of search outputs identified intervention types, methods used, sample sizes, intervention periods, knowledge, attitude and practice variables, other outcomes and listing of priority systematic review topics, using pre-determined criteria. All reviewed studies were found to be effective despite adopting different intervention approaches. Furthermore, identifying and prioritizing reviews greatly improves future malaria interventions and results thereof, thereby maximising opportunities to deliver appropriate and evidence-based healthcare.
