- Passage of pathogen from mother to baby immediately before and after birth is called Vertical transmission.
Additional Information
- The rate and risk of vertical transmission is based on;
- Involvement of Intervention.
- Presence of anti-retroviral drug therapy.
- Immune status.
- Absence of intervention and absence of ARV cause 15%-45% risk.
- With ARV treatment the vertical transmission risk is reduced up to 2%.
