Vektorivälitteisessä

Vektorivälitteisessä refers to something transmitted or spread through vectors. In epidemiology, this describes diseases that are transmitted from one host to another by an intermediary organism, typically an arthropod. These intermediary organisms are known as vectors. Common vectors include mosquitoes, ticks, flies, and fleas. The pathogen, such as a virus, bacterium, or parasite, resides within the vector and is transferred to a new host through actions like a bite or defecation. Examples of vector-borne diseases include malaria, dengue fever, Lyme disease, and Zika virus. The control of vector-borne diseases often involves targeting the vector population through methods like insecticide application, habitat modification, and personal protective measures. The term can also be used in other contexts, such as in engineering or physics, to describe phenomena that are mediated or carried by a vector quantity.
