Clinical and epidemiological characteristics among probable and confirmed patients with mpox in Sierra Leone reported from January to May 2025
Bibliographic record
Abstract
We analyzed available mpox cases reports in Sierra Leone from January to June 2025 following a historic increase in mpox cases across multiple urban and rural regions in the country. Here, we assessed demographic and clinical data from 187 case reports. Mpox case reports in this study were primarily from Bo (86/187; 46.0%) and Freetown (48/124; 25.7%). Most case reports were from male patients (101/187; 54.0%) as compared to females (86/187; 46.0%), with an overall median age of 26 years (IQR 22-34). The median age was higher among males (30 years; IQR 25-39) then females (24 years; IQR 21-27). Rash, fever, headache, lesions, and generalized pain were reported for all patients, where data was reported. Lymphadenopathy, muscle pain, sore throat, and cough were reported less commonly. Age- and sex-specific interventions, as well as community engagement that includes historically stigmatized groups are critical for mpox containment and mitigation measures in Sierra Leone.

Full frame machine prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
