Abstract

fetched live from OpenAlex

Introducción: Las políticas de salud pública para la disminución de la incidencia, transmisión y mortalidad de la COVID-19 se enfocan en medidas extradomiciliarias y descuidan el contagio dentro del hogar. El objetivo fue estimar la tasa de ataque secundario domiciliario de SARS-CoV-2. Material y Métodos: Se realizó una revisión sistemática de estudios observacionales que evaluaron la transmisión domiciliaria de SARS-CoV-2 publicados entre diciembre de 2019 y el 1 setiembre de 2021 en las bases de datos Medline, Scopus, LILACS y Google Scholar. La definición de contacto domiciliario se refirió a toda persona que habitaba la misma vivienda que el paciente índice. El riesgo de sesgo fue evaluado con una versión modificada de la escala Newcastle-Ottawa. Se realizó un metaanálisis con un modelo de efectos aleatorios para calcular la tasa de ataque domiciliaria, subanálisis con variables sociodemográficas, epidemiológicas y comorbilidades, así como metaregresión. Resultados: De 4491 estudios encontrados, 44 fueron incluidos en el análisis. La tasa de ataque secundario domiciliario general fue de 27.7% (IC95%: 23% - 32.7%). Además, fue mayor cuando el caso índice era sintomático (28.3%, IC95%: 8.1% - 54.7%) o el contacto era adulto mayor (42.3%, IC95%: 32% - 52.9%). Asimismo, la tasa fue mayor cuando los contactos domiciliarios presentaban diabetes mellitus (57.4%, IC95%: 45.2% - 69.3%) e hipertensión arterial (51.1%, IC95%: 38% - 64.1%). Conclusiones: La tasa de ataque secundario domiciliario de SARS-CoV-2 fue de 27.7%, siendo mayor al tener un caso índice adulto, contacto adulto mayor y contacto con diabetes mellitus o hipertensión arterial.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
