Which are the most common arthropod vectors of disease?
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.
What are arthropod-borne infections?
Arthropod-borne viruses, that is, arboviruses, belong to different virus families and genera and are maintained through transmission between vertebrate hosts by virus-infected blood feeding arthropods (mosquitoes, sandflies, biting midges, and ticks).
Which are the vector-borne diseases?
Vector-Borne Disease: Disease that results from an infection transmitted to humans and other animals by blood-feeding anthropods, such as mosquitoes, ticks, and fleas. Examples of vector-borne diseases include Dengue fever, West Nile Virus, Lyme disease, and malaria.
What is a biological vector give two examples?
Vectors are frequently arthropods, such as mosquitoes, ticks, flies, fleas and lice. Vectors can transmit infectious diseases either actively or passively: Biological vectors, such as mosquitoes and ticks may carry pathogens that can multiply within their bodies and be delivered to new hosts, usually by biting.
Which of the following spirochete caused diseases is transmitted by an arthropod?
It is an arthropod-borne infection caused by spirochetes of the Borrelia genus. Spirochetes are a unique species of bacteria that also cause syphilis, Lyme disease, and leptospirosis. The fever relapses result from spirochetal antigenic variation. Relapsing fever, if untreated, may be fatal.
Which of the following arthropods is the vectors of Lyme disease?
| Arthropod Vector | Disease |
|---|---|
| Tick: Ixodes sp. | Lyme disease |
| Tick: Dermacentor variabilis, Amyblyomma americanum | Ehrlichiosis, Sennetsu fever |
| Tick: Dermacentor sp. | Colorado Tick Fever |
| Tick: Amyblyomma americanum | No name for disease yet; only two reported cases; fever, fatigue, diarrhea, thrombocytopenia, and leukopenia |
What arthropod or intermediate vector-borne disease means?
Vector-borne diseases are infections transmitted by the bite of infected arthropod species, such as mosquitoes, ticks, triatomine bugs, sandflies, and blackflies. Arthropod vectors are cold-blooded (ectothermic) and thus especially sensitive to climatic factors.
How are vector borne diseases transmitted to humans?
Vector-borne diseases are transmitted among their human, animal, or plant hosts by arthropods, usually insects. A broader definition of vector-borne disease recognizes that other animals can serve in the role of infectious disease vector by harboring pathogens that cause disease only in susceptible populations.
How are vector borne diseases preventable and preventable?
Many of vector-borne diseases are preventable, through protective measures, and community mobilisation. Vectors are living organisms that can transmit infectious pathogens between humans, or from animals to humans.
How does the EFSA work on vector borne diseases?
EFSA has produced 36 interactive storymaps that provide user-friendly information on vector-borne diseases – from their geographical spread, to the risk of introduction in the EU to prevention and control measures. The storymaps have been developed as part of a scientific opinion that will support risk managers to prioritise control measures.
Where is the highest burden of vector borne diseases?
The burden of these diseases is highest in tropical and subtropical areas and they disproportionately affect the poorest populations. Since 2014, major outbreaks of dengue, malaria, chikungunya yellow fever and Zika have afflicted populations, claimed lives and overwhelmed health systems in many countries.
