Cholera is neither host nor the vector. Cholera is a disease caused by vibrio cholerae bacteria.
The vector is how the illness is spread. In cholera's case, the vector is contaminated water. That is how cholera is spread.
Vector, can transmit cholera; the disease.

Humans are the only known host of VZV.
Vector
An organism that carries a disease-causing microorganism from one host to another is called a vector. An example of a vector is a deer tick carrying Lyme disease.
Competent cells if i not mistaken
A biological vector is an organism that carries disease from one host into another. Some examples include rats, mice, houseflies and mosquitoes.
A vector which can replicates in two different host, eg; in bacteria and in yeast

The vector (the way the illness is spread) is mainly through contaminated water. There are most likely other ways you can catch the bacteria, but contaminated water is where the index case starts.
In terms of Epidemiology a vector is an organism which transmits diseases to healthy organisms. A biological vector develops an infected organism in its body and passes it along to its host. e.g mosquito while a mechanical vector carry an infected organism to its host through its legs and other body parts. e.g flies.
