SARS-CoV-2 Delta variant re-emerges in US farmed mink and free-ranging white-tailed deer in 2022-2023.

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
American mink (Neogale vison) are susceptible to SARS-CoV-2, but little is known about virus circulation in mink since 2021. Here, in the first active surveillance study of SARS-CoV-2 in apparently healthy farmed mink in the United States, we find a ~0.9% (760/85,656) RT-PCR positivity rate among nasal swabs collected in 18 farms across six states during 2022-2023. Phylogenetic analysis of 293 viral genome sequences shows that human-adapted SARS-CoV-2 variants (e.g., Omicron) repeatedly spill over into mink. Surprisingly, the detection of a Delta lineage virus (AY.39) on a mink farm four months after its last detection in humans within the same state suggests prolonged unsampled transmission. The spread of mink-adapted AY.39 viruses from a mink farm to neighboring free-ranging white-tailed deer represents a rare instance of SARS-CoV-2 transmission between livestock and wildlife. These findings demonstrate the value of active surveillance for identifying subclinical infections and interspecies transmission between humans, mink, and wildlife.
