Basile [38]

The right option is D. vector-borne

Diseases carried from person to person through other hosts, such as animals or insects, are known as vector- borne diseases.

Most of these hosts are arthropod vectors which are bloodsucking insects such as mosquitoes, ticks, triatomine bugs, sandflies, and blackflies. Examples of vector-borne diseases include West Nile fever which is transmitted through the bite of an infected Culex mosquito, Leishmaniasis which is transmitted through the bite of an infected female sandfly and Tick-borne encephalitis (TBE) which is transmitted by ticks.
