Range expansion of potential vectors and emerging pathogens, climate change, pesticide resistance, human encroachment on vector habitat, and international travel have all contributed to increased vector-human interactions and the health burden from vector-borne diseases. Vector-borne diseases are infections transmitted by the bite of infected arthropod species, such as mosquitoes, ticks, triatomine bugs, sandflies, and blackflies. Heart attacks, coronary heart disease and congestive heart failure are all common.

There are also important non-arthropod vectors of disease, including mammals and birds.
The four major types of vectors are plasmids, bacteriophages and other viruses, cosmids, and artificial chromosomes.
These are the major causes of disease in many tropical and subtropical countries. The purpose of vector control is to limit contact between humans and vectors, and to reduce vector populations or their life expectancy so that they are unable to transmit disease.

Arthropod vectors are cold-blooded (ectothermic) and thus especially sensitive to climatic factors. The best protection from mosquito-borne diseases is preventing the mosquito bites.
