Vector competence and vectorial capacity

Vector competence refers to the ability of mosquitoes to receive a disease agent microorganism (arbovirus etc.) from the reservoir host and then later transmit the infectious agent to another susceptible host.
Vectorial capacity includes a number of factors like vector competence, mosquito population density, host preferences, biting rate, immunity of the mosquitoes etc.
To be an effective vector, mosquitoes must have a high vector competence and vectorial capacity.
