'''Vertical transmission''', also known as '''mother-to-child transmission''', is the [[transmission (medicine)|transmission]] of an [[infection]] or other disease from mother to child immediately before and after birth during the [[perinatal]] period. A pathogen's '''transmissibility''' refers to its capacity for vertical transmission. The concept of vertical transmission is also used in [[population genetics]] to describe inheritance of an [[allele]] or condition from either the father or mother. |
|||
Vertical transmission tends to evolve benign [[symbiosis]]. It is therefore a critical concept for [[evolutionary medicine]]. |

Because a pathogen's ability to pass from parent to child depends significantly on the hosts' ability to reproduce, pathogens' transmissibility tends to be inversely related with their virulence. In other words, as pathogens become more harmful to and thus decrease the reproduction rate of their host organism, they are less likely to be passed on to the hosts' offspring since there will be fewer offspring.<ref>{{cite journal | title=An empirical study of the evolution of virulence under both horizontal and vertical transmission | last1=Stewart | first1=AD | last2=Logsdon | first2=JM | last3=Kelley | first3=SE | journal=Evolution | year=2005 | month=April | volume=59 | issue=4 | pages=730–739 | doi=10.1554/03-330 | pmid=15926685}}</ref> |

In [[Dual inheritance theory|Dual Inheritance Theory]], vertical transmission refers to the passing of cultural traits from parents to children.<ref>Cavalli-Sfornza, L. and M. Feldman. 1981.
