arbovirus

 [ahr´bo-vi″rus]
a term used by epidemiologists to refer to any of numerous viruses that replicate in blood-feeding arthropods such as mosquitoes and ticks and are transmitted to humans by biting. adj., adj arbovi´ral.

ar·bo·vi·rus

(ar'bō-vī'rŭs),
A name for a large, heterogeneous group of RNA viruses. There are more than 500 species, which are distributed among several families (Togaviridae, Flaviviridae, Bunyaviridae, Arenaviridae, Rhabdoviridae, Reoviridae), and have been recovered from arthropods, bats, and rodents; most, but not all, are arthropod borne. These taxonomically diverse animal viruses are unified by an epidemiologic concept, that is, transmission between vertebrate hosts by blood-feeding (hematophagous) arthropod vectors (for example, mosquitoes, ticks, sandflies, and midges). Although about 100 species can infect humans, in most instances diseases produced by these viruses are of a mild nature and difficult to distinguish from illnesses caused by viruses of other taxonomic groups. Apparent infections may be separated into several clinical syndromes: undifferentiated-type fevers (systemic febrile disease), hepatitis, hemorrhagic fevers, and encephalitides.

arbovirus

/ar·bo·vi·rus/ (ahr´bo-vi″rus) any of a group of viruses, including the causative agents of yellow fever, viral encephalitides, and certain febrile infections, transmitted to humans by various mosquitoes and ticks; those transmitted by ticks are often considered in a separate category (tickborne viruses).arbovi´ral

arbovirus

(är′bə-vī′rəs)
n.
Any of a large group of RNA viruses that are transmitted by arthropods, such as mosquitoes and ticks, and include the causative agents of encephalitis, yellow fever, and dengue.

arbovirus

[är′bōvī′rəs]
any one of more than 300 viruses transmitted by the saliva of insects. The majority of human infections are asymptomatic, but symptomatic infections can be characterized by fever, rash, and bleeding into the viscera or skin. Some lead to encephalitis with fatality or permanent neurological damage. Vertebrate infection occurs when a contaminated arthropod takes a blood meal. Dengue, yellow fever, and equine encephalitis are three common arboviral infections. Treatment is symptomatic for all arbovirus infections. Vaccines have been developed to prevent infection from some arboviruses. Also called arthropod-borne virus. arboviral, adj.

arbovirus

A large, heterogeneous group of single-stranded RNA viruses with an envelope surrounding the capsid, which are so named as most are transmitted by the saliva of haematophagous arthropod bites, i.e., are arthropod-borne.
 
Clinical findings
Most arboviral infections are mild, but may include haemorrhagic fever, encephalitis, systemic fever complex and hepatitis.
 
Vectors
Mosquitoes, sandflies, ticks.
 
Families
Arenavirus, Bunyaviridae, Flaviviridae, Reoviridae, Rhabdoviridae, Toagaviridae.

arbovirus

Any of the hundred or so viruses transmitted by an arthropod vectors such as mosquitoes, bugs, lice, ticks and mites. The group includes viruses that cause various forms of ENCEPHALITIS, haemorrhagic fevers, YELLOW FEVER, DENGUE, Kyasanur Forest disease, Rift Valley fever and Chikungunya Forest fever.

arbovirus

any virus that is ARTHROPOD-borne, e.g. the yellow-fever virus carried by the mosquito Aedes aegypti.

arbovirus

(arthropod-borne) one that replicates in an arthropod, which acts as a vector in transmission of the virus to a susceptible vertebrate host in which replication also occurs. See also togaviridae, bunyaviridae, reoviridae, rhabdoviridae, arenaviridae.
