The social face of Aedes control: women take the floor in a suburban district of Fortaleza, Brazil

Resumo O Aedes aegypti é um importante agente transmissor de afecções na atualidade, sendo o responsável por enfermidades como Zika, Chikungunya e os quatro sorotipos do Dengue. Por ocasião da relevância desse mosquito para o corpo social atual, investigações em Ecossaúde se tornam prementes, já que essa abordag em visa articular diferentes campos teóricos para entender as conexões históricas entre a natureza, a sociedade e a saúde. Partindo de uma premissa etnográfica, este estudo considerou as condições de desigualdade e injustiça que tornam vulneráveis a saúde de mulheres em torno do dengue, an alisando práticas e percepções destas acerca dos potencias criadouros existentes no espaço público. Para compor o estudo, utilizou-se a entrevista semiestruturada e a observação participante, com uso de diário de campo. A pesquisa contou com a participação de dez mulheres moradoras de um b airro periférico da cidade de Fortaleza, Ceará, Brasil, tendo ocorrido no período de janeiro a agosto de 2014. Da Análise de Conteúdo emergiu a categoria “ Iniquidade social, contexto e pr áticas no espaço público ” . A partir das narrativas, constatou-se que condi ções precárias de vida e evidente iniqui...

Conclusions/SignificanceOur results shed insights into the role ofompA gene in host-microbe interactions inAe.aegypti and confirm that CRISPR/Cas9 gene editing can be employed for genetic manipulation of non-model gut microbes. The ability to use this technology for site-specific integration of genes into the symbiont will facilitate the development of paratransgenic control strategies to interfere with arboviral pathogens such Chikungunya, dengue, Zika and Yellow fever viruses transmitted byAedes mosquitoes.

This report shows the need for an efficient surveillance system to control the spread of this virus in the population and suggests the use of saliva and urine samples as an alternative for the detection of OROV when serum samples are not available. PMID: 31787741 [PubMed - as supplied by publisher]

ero E Abstract Arboviral diseases caused by dengue (DENV), Zika (ZIKV) and chikungunya (CHIKV) viruses represent a major public health problem worldwide, especially in tropical areas where millions of infections occur every year. The aim of this research was to identify candidate molecules for the treatment of these diseases among the drugs currently available in the market, through in silico screening and subsequent in vitro evaluation with cell culture models of DENV and ZIKV infections. Numerous pharmaceutical compounds from antibiotics to chemotherapeutic agents presented high in silico binding affinity for th...

AbstractPurpose of ReviewIn this review, we present the overview of emerging and neglected viruses associated with liver involvement.Recent FindingsHepatitis E virus (HEV) emerged in the last two decades, causing hepatitis in many parts of the world. Moreover, liver involvement was also described in some emerging arboviral infections. Many reports showed dengue-associated liver injury; however, chikungunya, West Nile, tick-borne encephalitis, and Zika virus are rarely associated with clinically manifest liver disease. In addition, some neglected highly prevalent viruses such as adenoviruses and parvovirus B19 are capable o...

ABSTRACTAedes aegyptiandAedes albopictusare invasive mosquito species with geographic ranges that have oscillated within Florida since their presence was first documented. Local transmission of dengue, chikungunya, and Zika viruses serves as evidence of the public health importance of these two species. It is important to have detailed knowledge of their distribution to aid in mosquito control efforts and understand the risk of arbovirus transmission to humans. Through a partnership involving the University of Florida Institute of Food and Agricultural Sciences Cooperative Extension Service and the Florida Medical Entomolo...

Authors: Maniero VC, Rangel PSC, Coelho LMC, Silva CSB, Aguiar RS, Lamas CC, Cardozo SV Abstract A progressive increase in the circulation of arboviruses in tropical countries has been observed, accounting for 700,000 yearly deaths in the world. The main objective of this article was to identify the presence of Zika (ZIKV), dengue (DENV), and Chikungunya (CHIKV) viruses in immature stages of Aedes aegypti and Ae. albopictus. Household collections of immature phases of the vectors were carried out in the years 2015 and 2016. A total of 2902 dwellings were visited and the rate of infestation with larvae and pupae of ...

Conclusions: Aedes albopictus is responsible for the current outbreaks. The spread of Aedes albopictus and Aedes japonicus increases the risk of the autochthonous transmission of these viruses. Although native species could contribute to their transmission, more studies are still needed to assess that risk.

E. Franz The arboviral disease cycle requires that key tissues in the arthropod vector become persistently infected with the virus. The midgut is the first organ in the mosquito that needs to be productively infected with an orally acquired virus. Following midgut infection, the virus then disseminates to secondary tissues including the salivary glands. Once these are productively infected, the mosquito is able to transmit the virus to a vertebrate host. Recently, we described the midgut dissemination pattern for chikungunya virus in Aedes aegypti. Here we assess the dissemination pattern in the same mosquito species ...

Rampazzo R Abstract Arboviruses have been emerging and reemerging worldwide, predominantly in tropical and subtropical areas. As many arbovirus infections, including dengue (DENV), Zika (ZIKV), and chikungunya (CHIKV), have similar signs and symptoms, clinical diagnosis of arbovirus infections is challenging. Therefore, reliable laboratory tests are necessary to improve the clinical management of patients with suspected arbovirus infections. Real-time reverse-transcription PCR (RT-qPCR) is among the more effective methods to distinguish these viruses. The aim of this study was to construct a unique positive exter...
