Estudos indicam que as mudanças climáticas poderão afetar a distribuição global de arboviroses, influenciando fatores como sobrevivência vetores, patógenos e transmissão viral. Assim, buscou-se nesse estudo realizar uma revisão sistemática dos artigos mais recentes – publicados entre 2015 2020 - relativos essa temática. Após aplicação critérios elegibilidade, 28 foram selecionados para análise....

Dengue (DENV), chikungunya (CHIKV), and Zika (ZIKV) virus infections are widespread throughout the Rio de Janeiro state. The co-circulation of these emergent arboviruses constitutes a serious public health problem, resulting in outbreaks that can spatially temporally overlap. Environmental conditions favor presence, maintenance, expansion Aedes aegypti, primary vector urban arboviruses. This st...

Plaque development of 42 arbovirus serotypes, representing 17 serogroups, was studied in a clonal line (PS Y-15) of porcine kidney. The arboviruses plaqued within 3 to 7 days, with plaque diameters ranging from 1 to 5 mm. Mouse mortality and cell infectivity end points were compared with 24 arboviruses. Arbovirus LD(50) end points in mice exceeded the porcine kidney monolayer plaque-forming uni...

We report a case of laboratory-confirmed Zika virus infection imported into Europe from the Americas. The patient developed fever, rash, and oedema of hands and feet after returning to Italy from Brazil in late March 2015. The case highlights that, together with chikungunya virus and dengue virus, three major arboviruses are now co-circulating in Brazil. These arboviruses represent a burden for...

The traditional view of interactions between arboviruses and their arthropod vectors is that vector hosts become increasingly resistant to parasites; parasite attenuation occurs; or through the process of coevolution, resistance and attenuation occur in concert. Detrimental effects from arboviruses are only seen when vector and virus are not yet well adapted. Results from this study indicate th...

The protein synthesis machineries of two distinct phyla of the Animal kingdom, insects of Arthropoda and mammals of Chordata, have different preferences for how to best encode proteins. Nevertheless, arboviruses (arthropod-borne viruses) are capable of infecting both mammals and insects just like arboviruses that use insect vectors to infect plants. These organisms have evolved carefully balanc...

In this review, we mainly focus on zoonotic encephalitides caused by arthropod-borne viruses (arboviruses) of the families Flaviviridae (genus Flavivirus) and Togaviridae (genus Alphavirus) that are important in both humans and domestic animals. Specifically, we will focus on alphaviruses (Eastern equine encephalitis virus, Western equine encephalitis virus, Venezuelan equine encephalitis virus...

BACKGROUND In Japan, epizootic arboviral infections have severely impacted the livestock industry for a long period. Akabane, Aino, Chuzan, bovine ephemeral fever and Ibaraki viruses have repeatedly caused epizootic abnormal births and febrile illness in the cattle population. In addition, Peaton, Sathuperi, Shamonda and D'Aguilar viruses and epizootic hemorrhagic virus serotype 7 have recently...

Arboviruses have evolved a number of strategies to survive environmental challenges. This review examines the factors that may determine arbovirus emergence, provides examples of arboviruses that have emerged into new habitats, reviews the arbovirus situation in western Europe in detail, discusses potential arthropod vectors, and attempts to predict the risk for arbovirus emergence in the Unite...
