Wastewater and environmental surveillance as an early warning system and public health tool for mpox outbreak detection and management: a scoping review.
Article in BMC medicine, 2025. 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
backgroundWastewater and environmental surveillance (WES) has demonstrated the potential to detect signal for the mpox virus (MPXV), thereby supporting public health efforts to mitigate outbreaks. The aim of this scoping review was to document the use of WES as an early warning system and public health tool for mpox outbreak management.
methodsA systematic search was conducted in PubMed, Web of Science and Scopus in August 2024, and updated in April 2025, to identify eligible studies using the PCC framework.
resultsThe search yielded 256 records. Title and abstracts were screened for 140 records. Full text screening was done on the remaining 43 records, of which 10 further records were excluded. A total of 33 studies, published between 2022 and 2024, were included for synthesis in this review. Twenty-two studies reported a positive correlation/association between trends of MPXV in wastewater data and the reported cases on mpox. Four studies included in this scoping review reported the detection of MPXV in wastewater before clinical cases. Other studies reported negative associations, as well as false positive and false negative results from WES for mpox. Surveillance was predominantly conducted at wastewater treatment plants (91%), leaving a gap in surveillance of non-sewered settings. The qPCR method was reported by 61% of studies for molecular analysis. However, assessments of the qPCR method are needed to improve sensitivity and accuracy in the quantification of MPXV in wastewater.
conclusionsFurther research is needed to improve the capability of WES to provide early indication of mpox outbreaks and inform the accurate quantification of MPXV in wastewater to serve as an early warning system.
