Vector-Borne Diseases are diseases that are passed on to humans through the bite of a ‘vector’. A ‘vector’ is a blood feeding insect or other organism that can pick up an infection from one host (a human or animal) and pass it on to another host through a bite. Some mosquitoes and tick species are examples of vectors. West Nile Virus and Eastern Equine Encephalitis are examples of Vector-Borne Diseases that can be passed on by mosquitoes. Lyme disease is an example of a Vector-Borne Disease that can be passed on by ticks.
