Public Spaces as Hotspots of Zoonotic Gastrointestinal Parasite Transmission: Evidence from Small Animal and Soil Surveillance in Malaysia.
Article in Journal of epidemiology and global health, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. 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
backgroundPublic spaces such as parks and playgrounds offer social and ecological benefits to communities, but it might also pose public health risks. This epidemiological survey investigated the presence and risk factors of zoonotic parasites in faecal and soil samples collected from 60 public spaces across Kuala Lumpur and Selangor, Malaysia.
methodsEggs, cysts and larvae of parasites were collected from 71 faecal and 300 soil samples using flotation-sedimentation techniques. Species identification was done using both morphological and conventional PCR.
resultsA total of 71 faecal samples were collected, comprising 40 cat faeces and 31 dog faeces. Of these, 63 samples (88.7%) were positive for at least one intestinal parasite. The prevalence of parasite in cat faeces (95.0%, 38/40) was higher than dogs (80.7%, 25/31). Overall, six genera of parasites were detected in faecal samples. Cystoisospora spp. (62.0%) was the most prevalent, followed by hookworms (46.5%) and Giardia spp. (22.5%). Among the 33 faecal samples that tested positive for hookworms, Ancylostoma ceylanicum was the most common species (81.8%). Hookworm coinfections with Cystoisospora spp. were commonly detected in faecal samples (37.5%). Viability testing revealed that 37.7% of collected hookworm eggs and 74.6% of collected Toxocara eggs were viable. In soil samples, hookworm larvae were found in 28 out of the 300 samples, and 16 out of 60 sampling sites (26.7%). Hookworm burdens were significantly higher in rural areas and beaches. Risk factor analysis revealed that the presence of dustbin was associated with reduced hookworm infections (OR=0.075, 95% CI: 0.007-0.520) in dogs. Higher odds of hookworms were found in cat faeces (OR=4.961, 95% CI: 1.10-25.98) and soil (OR=5.77, 95% CI: 1.54-20.26) from residential parks. Notably, faecal-soil concordance was observed at 43.8% sampling sites, all located in residential parks. It highlights that these areas are potential active transmission hotspots.
conclusionsThese findings provide essential information for public health officials to develop targeted interventions to reduce the risk of transmission of zoonotic parasites in public spaces.
