Seasonal dynamics of hedgehog-borne ticks and severe fever with thrombocytopenia syndrome virus in Beijing's urban parks.

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
Severe fever with thrombocytopenia syndrome virus (SFTSV), an emerging tick-borne pathogen, has caused a rising number of human cases in the urban-rural fringe of Beijing since 2021. This study explores the seasonal dynamics of hedgehog-associated ticks and SFTSV transmission in urban parks of Beijing. Surveys across six parks revealed distinct activity patterns: adult Haemaphysalis longicornis peaked in summer, while nymphs dominated spring and autumn. All collected H. longicornis belonged to parthenogenetic populations. A near-complete SFTSV genome (C4 strain) was identified in a tick collected from Taoranting Park, suggesting multiple viral introductions into Beijing. Serological analysis showed that > 50% of hedgehogs carried SFTSV-neutralizing antibodies in spring; yet seropositivity declined markedly in summer and autumn, indicating recurrent infections and implicating hedgehogs as potential reservoirs. These findings reveal an urban SFTSV transmission cycle maintained by hedgehogs and parthenogenetic H. longicornis, emphasizing the urgency of enhanced surveillance and public health interventions to curb urban zoonotic risks.
