Fever, Headache, Fatigue and Chancre in a Traveller Returning from Tanzania
Bibliographic record
Abstract
Case PresentationA previously healthy 52-year-old man presented in January 2009 with a 48 h history of fever, headache, nonpurulent conjunctivitis, fatigue and a left subclavicular chancre.His symptoms began as he was returning from a three-week trip to East Africa during which he ascended Mount Kilimanjaro, visited the Ngorongoro crater, the Serengeti and a resort in Zanzibar.He denied any insect bites or exposure to fresh water.He had suffered a sunburn in Zanzibar and, over four days, noticed the evolution of a left subclavicular chancre.He had received pretravel counselling and had accepted all relevant vaccinations and was compliant with his malaria prophylaxis.He denied any HIV risk factors.On presentation, the patient was febrile (40.6°C), but his other vital signs were within normal limits.A sunburn was noted on his chest, as well as a 4 cm × 3 cm chancre below his left clavicle (Figure 1).This lesion was indurated, nontender and nonfluctuant.A physical examination and laboratory investigations were otherwise unremarkable.A diagnostic test was performed.
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.

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.
