These are diseases caused by bacteria and spread to humans by arthropods.

Vector borne bacterial diseases

These are diseases spread by parasitic arthropods.

Vector borne parasitic diseases

Arboviruses are viruses continuously spread in nature through biological transmission  from arthropods to humans and animals.

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

Vector Borne Diseases

“Vector-Borne Diseases.” World Health Organization, World Health Organization, www.who.int/news-room/fact-sheets/detail/vector-borne-diseases. 

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

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
