Metatranscriptomics profiling reveals rodent- and shrew-borne viral diversity and evolutionary relationships in Guangzhou, China.

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
Emerging zoonotic infectious diseases, predominantly caused by viruses, pose increasing public health threats globally. Rodents and shrews are natural hosts for a variety of zoonotic viruses. Guangzhou is one of China's most densely populated cities and experiences frequent international and domestic population movements, making it a hotspot for infectious diseases. This study reports the metatranscriptomics virome of 208 rodents and shrews collected between June 2023 and December 2024 from four main urban areas (Tianhe, Baiyun, Liwan, Yuexiu) and five non-main urban areas (Zengcheng, Huadu, Conghua, Panyu, Nansha) in Guangzhou. Individual libraries were constructed from mixed tissue samples (liver, spleen, lung, and kidney) of each animal. Metatranscriptomics sequencing revealed diverse viral communities, identifying 24 viral strains across eight mammalian-associated viral families. Notably, we identified 17 known viruses and seven potentially novel viruses, including Seoul virus (5.2% prevalence in Rattus norvegicus from Panyu), Wenzhou mammarenavirus (13.2% in Rattus norvegicus from Conghua and Huadu), Jeilongvirus (29.4% in Rattus andamanensis from Panyu), and a divergent lineage of arteriviruses that may represent a new genus (maximum positivity rates of 2.9% in Rattus norvegicus and 5.7% in Rattus tanezumi). Phylogenetic analysis elucidated evolutionary relationships within key families such as Hantaviridae, Arenaviridae, Flaviviridae, and Parvoviridae, revealing distinct viral carriage patterns in Guangzhou City that are shaped by host species and geographical location. This is the first macro-level study of rodent and shrew viromes in Guangzhou and provides a scientific basis for strengthening surveillance of mammalian-associated viruses and preventing emerging zoonotic infectious diseases in the region.
