transmission

 [trans-mish´un]

2. the communication of inheritable qualities from parent to offspring.
horizontal transmission the spread of an infectious agent from one individual to another, usually through contact with bodily excretions or fluids, such as sputum or blood, that contain the agent.
vertical transmission transmission from one generation to another. The term is restricted by some to genetic transmission and extended by others to include also transmission of infection from one generation to the next, as by milk or through the placenta.

ver·ti·cal trans·mis·sion

1. transmission of a virus (for example, RNA tumor virus) by means of the genetic apparatus of a cell in which the viral genome is integrated;
2. for infectious agents in general, transmission of an agent from an individual to its offspring, that is, from one generation to the next. Compare: horizontal transmission.

vertical transmission

Epidemiology Mother-to-child transmission The transmission of an infection through the placenta to the fetus, as occurs in the 'TORCH' infections–toxoplasmosis, rubella, CMV, herpes, syphilis, and HIV. Cf Hereditary transmission, Horizontal transmission.
