vectorparasite
A vector parasite is a parasite that relies on a separate organism, a vector, to reach its vertebrate hosts and often to complete part of its life cycle. In vector-borne systems, the parasite spends developmental stages inside the vector and is transmitted to a new host when the vector takes a bite. Vectors are typically arthropods such as mosquitoes, ticks, sandflies, blackflies, lice, or fleas.
Prominent examples include Plasmodium species, which cause malaria and are transmitted by Anopheles mosquitoes; Leishmania species
Biology and transmission are shaped by interactions among the parasite, the vector, and the vertebrate host.
The concept is central to public health and veterinary medicine. Control strategies include reducing vector populations
