What is arthropod-borne virus?
Arboviral disease is a general term used to describe infections caused by a group of viruses spread to people by the bite of infected arthropods (insects) such as mosquitoes and ticks. These infections usually occur during warm weather months, when mosquitoes and ticks are active.
Which two viruses can be transmitted by arthropods?
The emergence of arthropod-borne viral diseases: A global prospective on dengue, chikungunya and zika fevers – PMC.
Is a arthropod-borne infection?
Disease History, Characteristics, and Transmission Humans contract arthropod-borne diseases when a pathogen, such as a bacteria or virus, is transmitted from its reservoir (natural host) to a human via the arthropod vector. The most common arthropod vectors are flies, fleas, ticks, mosquitoes, and lice.
How are arthropod-borne diseases transmitted?
Arthropods transmit parasites either by injection into the blood stream of the host directly via their salivary glands, or by forcing parasites into a pool of blood which develops when chewing the skin.
What are arthropod vectors?
Arthropod vectors include mosquitoes, flies, biting midges, ticks, mites, fleas, bugs, lice, and other arthropods that carry and transmit disease-causing organisms, or pathogens, from one host to another.
Which viruses have vector arthropods?
Dengue virus (DENV), Chikungunya virus (CHIKV), and Zika virus (ZIKV) have caused large outbreaks on multiple continents, and large portions of the world’s population live in regions where there is a risk of DENV, CHIKV, or ZIKV transmission.
What are arthropods and vectors?
Arthropod vectors include mosquitoes, flies, biting midges, ticks, mites, fleas, bugs, lice, and other arthropods that carry and transmit disease-causing organisms, or pathogens, from one host to another. From: Hunter’s Tropical Medicine and Emerging Infectious Diseases (Tenth Edition), 2020.
Is a spider an arthropod?
Spiders are arachnids, a class of arthropods that also includes scorpions, mites, and ticks. There are more than 45,000 known species of spiders, found in habitats all over the world.
Which bacteria is transmitted by arthropods?
Anaplasma phagocytophilum, marginatum; Bartonella henselae; Borrelia burgdorferi, afzelii, garinii; Coxiella burnetii; Ehrlichia chaffeensis; Francisella tularensis; Rickettsia prowAZekii, akari, rickettsii and Yersinia pestis are also known as arbobacteria.

Which of the following diseases is transmitted by an arthropod vector?
List of vector-borne diseases, according to their vector
| Vector | Disease caused |
|---|---|
| Blackflies | Onchocerciasis (river blindness) |
| Fleas | Plague (transmitted from rats to humans) Tungiasis |
| Lice | Typhus Louse-borne relapsing fever |
| Sandflies | Leishmaniasis Sandfly fever (phlebotomus fever) |
How are arthropods transmitted?
The vast majority of VBDs are transmitted through bloodsucking arthropod species, which during their blood meal ingest pathogens from an infected host (human or animal) and transmit it into a new host after a period of incubation during which the pathogen has replicated.
