Varicella and the pregnant woman: Prevention and management
Bibliographic record
Abstract
Infection with varicella zoster virus (VZV) is often considered a childhood 'right of passage'; however, primary infection occurring in women of child-bearing age can have significant adverse consequences both for the mother and for her fetus. During the first trimester, primary VZV infection may result in stillbirth or a baby born with the stigmata of the congenital varicella syndrome, while infection in the peripartum period can result in neonatal varicella, which carries a significant mortality rate despite appropriate antiviral therapy. Varicella in pregnant women can progress to pneumonitis and other severe sequelae that may also compromise the viability of the fetus. Exposure to VZV most commonly occurs in the community or from children in the household, but occasionally, exposure may occur in the hospital environment. Determining a woman's serostatus prior to pregnancy is advised, as effective vaccines are now available and should be administered to non-pregnant seronegative women of child-bearing age. Clinical practice guidelines for management of a pregnant woman exposed to VZV are presented.

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.
