“…In Brazil, climatic and geographic conditions are very favorable for the proliferation and dissemination of mosquitoes and their viral microbiota: frequent rainfall, year-round high temperature and dense forests. In the last few years Brazil has faced multiple epidemics caused by mosquito-borne viruses such as dengue virus, Zika virus and yellow fever virus [ 6 , 7 , 8 , 9 ]. These factors highlight the need for the comprehensive surveillance of virus diversity in mosquitoes.…”

Advancements in next-generation sequencing and bioinformatics have expanded our knowledge of the diversity of viruses (pathogens and non-pathogens) harbored by mosquitoes. Hubei reo-like virus 7 (HRLV 7) was recently detected by the virome analysis of fecal samples from migratory birds in Australia. We now report the detection of RNA-dependent RNA polymerase sequences of HRLV 7 in pools of Aedes aegypti and Culex quinquefasciatus mosquitoes species from the Brazilian Amazon forest. Phylogenetic inferences indicated that all HRLV 7 strains fall within the same independent clade. In addition, HRLV 7 shared a close ancestral lineage with the Dinovernavirus genus of the Reoviridae family. Our findings indicate that HRLV 7 is present in two species of mosquitoes.

“…Information on cISF is very limited so far and, therefore, not much can be concluded about their frequency, distribution, host range and genetic divergence in this country. However, in the last few years Brazil has been facing multiple epidemics caused by flaviviruses such as dengue virus, Zika virus and yellow fever virus [47,48,49,50]. This fact will probably lead to an increase in surveillance and monitoring studies.…”

Classical insect-specific flaviviruses (cISFs) have been widely detected in different countries in the last decades. Here, we characterize the near full-length genomes of two cISFs detected in mosquitoes collected in the city of Macapá, state of Amapá, Amazon region of Brazil. A total of 105 pools of female mosquitos were analyzed by next-generation sequencing (NGS). Comparative genomics and phylogenetic analysis identified three strains of cell fusing agent virus (CFAV) and two of Culex flavivirus (CxFV). All sequences were obtained from pools of Culex sp., except for one sequence of CFAV detected in a pool of Aedes aegypti. Both CxFV strains are phylogenetically related to a strain isolated in 2012 in the Southeast region of Brazil. The CFAV strains are the first of this species to be identified in Brazil and one of them is highly divergent from other strains of CFAV that have been detected worldwide. In conclusion, CFAV and CxFV, circulate in mosquitoes in Brazil. One strain of CFAV is highly divergent from others previously described, suggesting that a novel strain of CFAV is present in this region.

“…As updated in June 2018, dengue incidence was remarkably low, while Chikungunya occurrence paralleled the incidence observed in 2016 . In contrast, a large yellow fever outbreak occurred in the northeast of Minas Gerais state in 2017, with over 3000 notified cases . Variations in the incidence of arboviral diseases such as dengue and yellow fever have been documented in various settings .…”

The Zika virus infection outbreak in Brazil in 2014 to 2015 resulted in the identification of previously unknown consequences of the disease, including the notorious microcephaly among many defects in fetuses born to women infected during pregnancy. A number of individuals were involved in this remarkable discovery, from the detection of viral circulation in the country to the studies on the causal link with congenital abnormalities and the provision of awareness and social support to families affected by the disease. In this article, we review the background to this experience, describing aspects of the epidemiology, medical research, and scientific response to the Zika virus outbreak in Brazil.
