Abstract

fetched live from OpenAlex

Lassa virus (LASV) is maintained in and transmitted by Mastomys natalensis across West Africa. To date, few studies have addressed transmission of LASV between rodents. Here, we experimentally assessed the potential for sexual transmission of LASV in Mastomys. Intravaginal challenge led to systemic infection in females within 7 days of inoculation and persisted throughout the study. Percutaneous injection of males similarly resulted in a systemic infection, with LASV documented in reproductive organs and sperm for 21-42 days. Our data support the potential of sexual transmission of LASV in rodents, and intravaginal infection is potentially conducive to intrauterine transmission of LASV.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
