Infectious medical waste (IMW) and disease transmission: A critical public health challenge in Africa and the global implications - A systematic review.
Article in Journal of public health research, 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
Background: Infectious Medical Waste (IMW) from both human and animal healthcare sources have the potential to transmit diseases in human populations due to its pathogenic composition. Conversely, a paucity of data regarding cause-and-effect relationships inhibits our understanding of the extent to which disease transmission occurs. In parts of Africa where the management of IMW is not prioritized, the risks to public health, along with its global implications cannot be ignored. Methodology: A systematic literature search following the PRISMA guidelines was conducted across five electronic databases including PubMed, Embase, Scopus, ProQuest and Ovid. Relevant studies were identified using keywords such as 'infectious medical waste', 'infectious diseases', 'routes of infection', 'route of transmission', 'epidemics', 'diseases', 'sub-Sahara Africa', and 'infectious waste management'. Results: Overall, 6721 articles were retrieved from the search, 6634 of which were excluded due to a lack of alignment with the study objectives. After screening, 87 studies were deemed eligible and were included in the review. Our findings identified 11 diseases that are potentially transmissible via IMW. These include Anthrax, Crimean-congo haemorrhagic Fever, Ebola Virus Disease, Hepatitis B, Hepatitis C, Human Immunodeficiency Virus, Lassa Fever, Measles, Monkeypox, Plague, and Rift Valley Fever. Disease transmission may occur via human contact with different classes of IMW, contaminated materials and accessories. Conclusions: Medical waste can be a source of infectious disease transmission. However, evidence of such a pathway is currently unavailable due to a paucity of scientific data. Therefore, further research is needed to establish cause-and-effect relationships.
