Most cases were men; about one third led to secondary transmission. Secondary transmission risk was highest among sexual, then household, contacts. Those groups should be the focus of response strategies and interventions. ## Linked entities - **Diseases:** monkeypox (MONDO:0002594) ## Full-text entities - **Diseases:** infected (MESH:D007239) - **Chemicals:** mpox (MESH:C051836) - **Species:** Monkeypox virus (no rank) [taxon 10244], Homo sapiens (human, species) [taxon 9606] ## Full text _Full body text omitted from this summary view._ Fetch the complete paper as Markdown: https://tomesphere.com/paper/PMC12928243/full.md ## Figures 2 figures with captions in the complete paper: https://tomesphere.com/paper/PMC12928243/full.md ## References 9 references — full list in the complete paper: https://tomesphere.com/paper/PMC12928243/full.md --- Source: https://tomesphere.com/paper/PMC12928243
