Strictly defined, the vectorial capacity is the daily rate at which future inoculations arise from a currently infective case, provided that all females mosquitoes biting that case become infected (Dye 1986).

What is vector and host?

One of the most obvious definitions is based on the recognition that most organisms we commonly recognize as being 'vectors' are hosts that transmit a pathogen while feeding non-lethally upon the internal fluids of another host.

What is difference between pathogen and vector?

In epidemiology, a disease vector is any living agent that carries and transmits an infectious pathogen to another living organism; agents regarded as vectors are organisms, such as parasites or microbes.
