vertical transmission
Passage of infectious agents from mother to child during pregnancy, delivery, or breastfeeding.
Full Definition
The transmission of pathogens from mother to offspring through transplacental, intrapartum, or postnatal routes. Vertical transmission can occur at different stages: antepartum (through placenta), intrapartum (during birth process), or postpartum (through breastfeeding). This mode of transmission is crucial in pediatric infectious disease as it determines timing of infection, clinical presentation, and prevention strategies. Medical editors must distinguish vertical transmission from horizontal transmission and understand that prevention strategies vary depending on the pathogen and transmission timing.
Usage
Usage note: Hyphenate when used as compound modifier; distinguish from 'congenital' which implies in-utero acquisition specifically.
In Context
- "Prevention of vertical transmission requires targeted interventions based on the specific pathogen and transmission route." — Maternal-fetal medicine guideline
- "The rate of vertical transmission varies significantly among different viral pathogens and gestational timing of exposure." — Infectious disease research paper
