Mosquitoes are one of the most important vectors of arboviruses. Common viruses transmitted by mosquitoes: dengue, zika, yellow fever, chikungunya, and many others. 

Mosquitoes and Emerging Pathogens

Common arthropods that are vectors are:
- Mosquitoes
- Ticks
- Sandflies
- Black flies
- Tsetse flies
- Lice
- Fleas
- Aquatic snails
- Triatome bugs

Vector borne disease is a disease that is transmitted to humans, plants, and animals by any arthropod species. 

Vector Borne Diseases

An invertebrate animal having an exoskeleton, a segmented body, and paired joint appendages. Member of the Arthropoda phylum.

Arthropods in Vector Borne Diseases

Vector borne pathogens allowed for easier and faster dissemination of emerging pathogens in 3 ways:
- it can be easily transmitted by blood-feeding arthropods
- it overcomes spatial, behavioral, and ecological barriers between animals and humans. Direct contact between host and reservoir is no longer needed
- complexity of vector transmission offers pathogens more opportunities to evolve and increase pathogenicity to humans
