Exploring the water, sanitation and hygiene status and health outcomes in Zimbabwe: a scoping review protocol.

BACKGROUND: The sixth United Nations Sustainable Development Goal emphasises universal access to clean water, sanitation and hygiene (WASH) to ensure human well-being as a fundamental human right for sustainable development. In Zimbabwe, WASH reforms began more than a century ago from the preindependence to postindependence era. However, countries face pressing challenges in improving their related health outcomes. Therefore, this scoping review aims to explore WASH status and how it influences health outcomes in Zimbabwe. METHODS AND ANALYSIS: The leading databases to be searched for relevant sources published in English with an unrestricted search back until May 2024 include PubMed, EBSCO, SAGE, SpringerLink, Cochrane Library, ScienceDirect, Scopus, Web of Science and African Journals Online. A search string was developed for retrieving literature, and reports from key stakeholders in the WASH sector will be included in this study as grey literature. The study will employ a two-step screening process for identifying relevant literature incorporating Cohen's kappa coefficient statistics to estimate the inter-rater reliability between two independent reviewers using Mendeley and Rayyan software. The Strengthening the Reporting of Observational Studies in Epidemiology checklist for observational studies and the Consolidated Standards of Reporting Trials checklist for randomised controlled trials will be used for the quality checks. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews will guide this study in terms of data collection, extraction and analysis from relevant literature. Data charting was used to present and interpret the findings. The entire process is scheduled to commence in June 2024, with the manuscript anticipated to be submitted to a journal in October 2024. ETHICS AND DISSEMINATION: This review will use only published data; therefore, no ethical clearance is required. The findings will be disseminated to relevant stakeholders through peer-reviewed journals, meetings, conferences, seminars and forums.

Malaria Severity in the Elimination Continuum: A Retrospective Cohort Study between Beitbridge and Lupane Districts in Zimbabwe, 2021-2023.

Malaria has created a resurgence crisis in Zimbabwe's elimination continuum, diverging from global commitment to malaria elimination by 2030. This retrospective cohort study aimed to determine the risk factors associated with severe malaria in the Beitbridge and Lupane districts. Multistage sampling was used to recruit 2414 individuals recorded in the District Health Information Software2 Tracker database. The study used IBM SPSS 29.0.2.0(20) for data analysis, and odds ratios (ORs) to estimate the relative risk (RR; 95% C.I; p < 0.05). The study revealed significant relative risks (p-value < 0.05) for individuals who had no Long-Lasting Insecticidal Nets (Beitbridge 47.4; Lupane 12.3), those who owned but used the LLINs (Beitbridge 24.9; Lupane 7.83), those who slept outdoors during the night (Beitbridge 84.4; Lupane 1.93), and adults (Beitbridge 0.18; Lupane 0.22) compared to the corresponding reference groups. Other factors showed varying RR: sex (Beitbridge 126.1), prompt treatment (Beitbridge 6.78), hosting visitor(s) (Lupane 6.19), and residence (Lupane 1.94) compared to the corresponding reference groups. Risk factor management needs to focus on increasing local awareness of malaria, universal LLINs coverage of indoor and outdoor sleeping spaces, community-based programs on proper and consistent LLIN usage, screening of visitors from malaria-endemic areas, comprehensive entomological activities, mixed malaria interventions in rural hotspots, and future research on local malaria transmission dynamics. While Zimbabwe has the potential to meet the global goal of malaria elimination, success depends on overcoming the risk factors to sustain the gains already made among malaria elimination districts.
