vectorial capacity 

EPIDEMIOLOGY

A term used in the context of an infection–e.g., malaria, transmitted by an insect or other vector, which is analogous to contact rate in directly-transmitted infections–e.g., community-acquired pneumonia.

Vectorial capacity is a function of:

• The vector’s density in relationship to its vertebrate host

• The frequency with which it takes blood meals from the host species

• The duration of latency in the vector

• The vector’s lifespan
