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

(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.

ar′bo·vi′ral adj.
ar′bo·vi·rol′o·gy (är′bō-vĭ-rŏl′ə-jē) n.

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.

En paises como Venezuela, donde la endemia es alta para otras arbovirosis como el dengue y mas recientemente chinkungunya, las autoridades de salud deben fortalecer sus sistemas de vigilancia para detectar precoz y oportunamente la introduccion del virus y afinar los metodos de diagnostico para confirmar la infeccion indice; sin embargo, las altas casuisticas para estos agentes virales parecen reflejar sistemas de vigilancia debilitados, no sensibles y poco oportunos, asi como escases de medidas de control para vectores, por ende surge la interrogante si este arbovirus se hara emergente en nuestro pais y si se establecera como los otros en forma endemo-epidemica y si esto llevara a alterar su comportamiento clinico y la severidad de la enfermedad?
