From Wikipedia, the free encyclopedia
Vector-borne diseases are human infections caused by bacteria, parasites, and viruses that are spread by vectors.[1] A vector is a living organism that spreads pathogens; in other words, it carries disease-causing organisms from one host to another. Vectors are normally considered to be invertebrate animals, usually arthropods, but also include rodents, which carry the infectious disease from a reservoir to a susceptible host.[2] Vectors of human disease are typically a species of mosquitoes, ticks, flies, and fleas that are able to transmit bacteria, viruses, or parasites to humans and other vertebrate hosts.[3] A disease that is transmitted to humans, plants, or animals by any agent, arthropod, or fomite is a vector-borne disease.[4]
