Visceral leishmaniasis & HIV co-infection in Bangladesh: Investigating prevalence and policy recommendations.
Article in Journal of infection and public health, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundHuman Immunodeficiency Virus (HIV) co-infection has emerged as a significant challenge in implementing the World Health Organization's (WHO's) strategic interventions to eliminate visceral leishmaniasis (VL) in co-endemic countries. VL-HIV co-infection results in rapid deterioration, higher mortality, and substantially increases the risk of developing VL, facilitating parasite transmission. Although Bangladesh has received official validation for the elimination of VL as a public health problem in 2023, determining the prevalence of VL-HIV co-infection became imperative to develop effective strategies to sustain the elimination status. Therefore, in this study, we aimed to investigate the prevalence of HIV infection in VL patients in Bangladesh.
methodsIn this cross-sectional study, a total of 656 VL, post kala-azar dermal leishmaniasis (PKDL), and relapsed VL patients were enrolled. and tested for HIV following national HIV testing guidelines. Furthermore, the knowledge and attitudes of 624 participants were assessed through one-to-one interviews using structured questionnaires.
findingsNone of the patients tested positive for VL-HIV co-infection. Only 9.46% of respondents demonstrated comprehensive HIV/AIDS knowledge and 40.06% had positive attitudes towards individuals living with HIV/AIDS. Age, educational status, and home visits by government healthcare workers showed significant positive associations with participants' knowledge and attitudes in multivariate regression analysis.
conclusionThe study found no cases of HIV coinfection among the screened VL cohort in Bangladesh. However, the unavailability or response refusal of 26.1% of previous patients may have introduced significant selection bias. Therefore, considering the substantial health implications and increasing HIV incidence in the general population, we recommend continued routine HIV testing in all VL patients in Bangladesh, aligning with the WHO recommendations. Coordination between the respective national programs is warranted to develop effective strategies to detect emergence of such co-infected cases.
fundingThis study was conducted with the financial support of the UNICEF/UNDP/World Bank/WHO Special Programme for Research and Training in Tropical Diseases (TDR).
