  • Implementing community case management of malaria

    Open AccessEvelyn Waweru, Moses C Kiti et al.ARTICLEPLOS Global Public Health2026

    Malaria detection in Kilifi, County, primarily relies on intermittent active surveillance at healthcare facilities. To strengthen control of uncomplicated malaria, community health promoters (CHPs) were engaged in community health education, case detection, and treatment. This study examines lessons from integrating CHPs in community case management of malaria (CCMm). We use a mixed-method, concurrent cross-sectional design, to document stakehold…

  • Regular Plasmodium falciparum importation onto Bioko Island, Equatorial Guinea, hampers malaria elimination from the island

    Open AccessThomas C Stabler, Ankit Dwivedi et al.ARTICLEPLOS Global Public Health2025

    The Bioko Island Malaria Elimination Project (BIMEP) has made significant progress in reducing the prevalence of Plasmodium falciparum on Bioko Island, Equatorial Guinea. However, like other malaria endemic islands like São Tomé and Principe and Zanzibar, Tanzania, elimination efforts are hampered by imported infections. In an effort to understand the local transmission dynamics and the influence of importation on Bioko Island’s P. falciparum pop…

  • Attractive targeted sugar baits for malaria control in western Kenya (ATSB-Kenya) – Effect of ATSBs on epidemiologic and entomologic indicators

    Open AccessCaroline Ogwang, Aaron M Samuels et al.ARTICLEPLOS Global Public Health2025

    Attractive targeted sugar baits (ATSBs) are a novel malaria control tool designed to target mosquitoes outdoors. We conducted a cluster-randomised trial to evaluate the impact of ATSBs on malaria indicators in Kenya. Seventy clusters (≥100 households/cluster) in Siaya county were randomly assigned (1:1) to intervention or control. Pyrethroid-only long-lasting insecticidal nets were distributed to all clusters, aiming for universal coverage. Two A…

  • A geo-enabled digital tool for microplanning and delivery of indoor residual spray in Zambia

    Open AccessAnne C Martin, Frazer Bwalya et al.ARTICLEPLOS Global Public Health2025

    Indoor residual spraying (IRS) is a vector control tool recommended by the WHO in areas of high malaria burden. Effective IRS implementation is complicated when up-to-date and accurate counts of structures eligible for IRS are unavailable; resultingly, programmatic spray coverage is typically calculated as the proportion of found structures that are sprayed. From 2016 – 2020 in Zambia, an open-source tool termed “Reveal,” was used to support digi…

  • A cluster-randomized trial of client and provider-directed financial interventions to align incentives with appropriate case management in retail medicine outlets

    Open AccessJeremiah Laktabai, Emmah Kimachas et al.ARTICLEPLOS Global Public Health2024

    ACTs are responsible for a substantial proportion of the global reduction in malaria mortality over the last ten years, made possible by publicly-funded subsidies making these drugs accessible and affordable in the private sector. However, inexpensive ACTs available in retail outlets have contributed substantially to overconsumption. We test an innovative, scalable strategy to target ACT-subsidies to clients with a confirmatory diagnosis. We supp…

  • March 2019 dengue fever outbreak at the Kenyan south coast involving dengue virus serotype 3, genotypes III and V

    Open AccessEric M Muthanje, Kimita Gathii et al.ARTICLEPLOS Global Public Health2022

    The first description of a disease resembling dengue fever (DF) was in the 15 th century slave trade era by Spanish sailors visiting the Tanzania coast. The disease, then associated with evil spirits is now known to be caused by four serotypes of dengue virus (DENV1-4) that are transmitted by Aedes mosquitoes. Kenya has experienced multiple outbreaks, mostly associated with DENV-2. In this study, plasma samples obtained from 37 febrile patients d…

  • Household modifications after the indoor residual spraying (IRS) campaign in Mozambique reduce the actual spray coverage and efficacy

    Open AccessMercy Opiyo, Ellie Sherrard-Smith et al.ARTICLEPLOS Global Public Health2022

    Indoor residual spraying of insecticides (IRS) is a key malaria vector control strategy. Whilst human attitude towards IRS is monitored before or shortly after implementation, human activities leading to the modification of insecticide-treated walls post-IRS are not. This could inadvertently reduce the protective effects of IRS. We monitored the extent of modifications to the sprayed indoor wall surfaces by household owners for six months post-IR…

  • India may need an additional metric to assess the endemicity of malaria in low surveillance districts

    Open AccessChander Prakash Yadav, Sanjeev Gupta et al.ARTICLEPLOS Global Public Health2022

    India’s National Framework for malaria elimination is essentially dependent on Annual Parasite Incidence (API). API is the primary criterion for classifying states and districts into different categories: intensified control, pre-elimination, elimination, prevention and re-establishment of malaria. However, API’s validity is critically dependent on multiple factors, one such important factor is Annual Blood Examination Rate (ABER) and is often co…

  • Plasmodium falciparum importation does not sustain malaria transmission in a semi-arid region of Kenya

    Open AccessChristine F Markwalter, Diana Menya et al.ARTICLEPLOS Global Public Health2022

    Human movement impacts the spread and transmission of infectious diseases. Recently, a large reservoir of Plasmodium falciparum malaria was identified in a semi-arid region of northwestern Kenya historically considered unsuitable for malaria transmission. Understanding the sources and patterns of transmission attributable to human movement would aid in designing and targeting interventions to decrease the unexpectedly high malaria burden in the r…

  • Spatial targeting of Screening + Eave tubes (SET), a house-based malaria control intervention, in Côte d’Ivoire

    Open AccessTiago Canelas, Edward Thomsen et al.ARTICLEPLOS Global Public Health2021

    New malaria control tools and tailoring interventions to local contexts are needed to reduce the malaria burden and meet global goals. The housing modification, screening plus a targeted house-based insecticide delivery system called the In2Care® Eave Tubes, has been shown to reduce clinical malaria in a large cluster randomised controlled trial. However, the widescale suitability of this approach is unknown. We aimed to predict household suitabi…
