Background: The COVID-19 pandemic has disrupted malaria control activities globally. Notably, high levels of excess malaria morbidity and mortality in low- and middle-income countries (LMICs) were reported. Although it is crucial to systematically understand the main causes of the disruption to malaria control and synthesize strategies to prepare for future pandemics, such studies are scarce. Therefore, this study aims to better identify barriers against and strategies for malaria control.
Methods: Following the PRISMA guidelines and through searches of electronic databases and Google Scholar, a systematic literature review was conducted to identify studies pertaining to malaria control published between January 2020 and December 2021. Only studies that discussed reported barriers and/or strategies related to malaria were included for the review. The Mixed Methods Quality Appraisal Tool (MMAT) and the Authority, Accuracy, Coverage, Objectivity, Date and Significance (AACODS) checklist were used for quality appraisal. Key information such as literature type, study design, setting and population, interventions, outcomes, barriers, and strategies were extracted. With an existing framework of four dimensions (accessibility, affordability, availability, and acceptability) further subdivided by the supply and demand sides, this study synthesized information on barriers and strategies related to malaria control and further categorized the strategies based on the time frame.
Results: From the 30 selected studies, 27 barriers and 39 strategies were identified. The lockdown measures, which mainly threatened geographic accessibility and availability of malaria control services, were identified to be the main barrier hindering effective mobilization of community health workers and resources. Among the identified strategies, clear risk communication strategies would alleviate psychosocial barriers, which challenged acceptability. Some strategies that cross-cut points across all four dimensions would, require systems-level integration to enhance availability and affordability of malaria control. The strategies were distinguished between short-term, for instant response, and mid to long-term for future readiness.
Conclusions: The pandemic resulted in complex barriers to malaria control, particularly imposing a double burden on LMICs. Identifying strategies to overcome said barriers provides useful insights in the decision-making processes for the current and future pandemic. Cross-cutting strategies that integrate all dimensions need to be considered. Health system strengthening and resilience strategy appropriate for country-specific context is fundamental.
