“…Inappropriate environmental conditions are factors that contribute to the high virus load in the human population, in addition to the lack of mass immunization and specific treatments for the majority of circulating arboviruses, and even their co-circulation [ 3 , 4 ]. The socioeconomic difficulties of the population, poor sanitary conditions and the accumulation of non-recyclable waste also contribute to the proliferation and abundance of mosquitoes that transmit these pathogens [ 5 , 6 ].…”

Aedes aegypti and Culex quinquefasciatus mosquitoes are vectors of different arboviruses that cause a large burden of disease in humans worldwide. A key step towards reducing the impact of arboviruses on humans can be achieved through integrated mosquito surveillance and control approaches. We carried out an integrated approach of mosquito surveillance and control actions to reduce populations of these insects along with a viral surveillance in a neighborhood of Recife (Northeastern Brazil) with high mosquito densities and arbovirus transmission. The actions were carried out in 40 different houses in the Nova Descoberta neighborhood. The area was divided into two groups, the control group using tools to monitor the mosquito density (1 OVT; 1 Double BR-ovt; monthly capture of alates) and the experimental group with control actions using surveillance tools in an intensified way (2 OVTs; 2 Double BR-ovts; fortnightly capture of alates; toxic baits). We evaluated the study’s impact on the mosquito density via the Egg Density (ED) and Adult Density (AD) over a period of 12 cycles of 28 days each. The collected adult mosquitoes were processed via RT-qPCR for DENV, CHIKV and ZIKV and, subsequently, the Minimum Infection Rate (MIR) was calculated. After 12 cycles, we observed a 91% and 99% reduction in Aedes ED and AD in the monitored properties, as well as a 76% reduction in the AD of Cx. quinquefasciatus in the same properties. Moreover, we detected circulating arboviruses (DENV and ZIKV) in 19.52% of captured adult mosquitoes. We show that enhancing entomological surveillance tools can aid in the early detection of possible risk areas based on vector mosquito population numbers. Additionally, the detection of important arboviruses such as ZIKV and DENV raises awareness and allows for a better selection of risk areas and silent virus spread. It offers supplementary information for guiding emergency mosquito control measures in the target area. The goal is to minimize human–vector interactions and, subsequently, to lower the risk of transmitting circulating arboviruses.

“…Esforços entre diferentes atores, nacionais e internacionais, conjugaramse no enfrentamento da crise sanitária, com distintas ênfases e perspectivas. Evidenciaram-se as intenções em potencializar ações de diagnóstico, prevenção, tratamento e controle da epidemia e seus efeitos, além de pesquisas com foco nas lacunas do conhecimento sobre as arboviroses, destacando o ZIKV e sua relação com a microcefalia e outras manifestações (Abrasco, 2016;Freitas et al, 2018;Albuquerque et al, 2018;Oliveira et al, 2020).…”

Resumo O artigo analisa a resposta federal dos Sistemas Nacionais de Vigilância em Saúde e de Vigilância Sanitária frente à epidemia do Zika vírus no Brasil, de 2015 a 2018, com foco nos contextos político-institucionais e no conteúdo das medidas governamentais desenvolvidas no período. O estudo ancorou-se na abordagem institucionalista histórica, compreendendo análise documental e entrevistas com atores-chave. A resposta se caracterizou pela priorização inicial da emergência sanitária na agenda política do governo federal, reduzindo-se ao longo do período, influenciada pelas crises financeira e política. Verificou-se multiplicidade de atores e instâncias voltadas à contingência, com certa articulação entre os dois sistemas, a partir de experiências pré-emergência próprias. O controle vetorial teve centralidade, valorizando ações intersetoriais e comunitárias, induzidas sobretudo pela Secretaria de Vigilância em Saúde do Ministério da Saúde e complementarmente pela Agência Nacional de Vigilância Sanitária. Observaram-se expressivas limitações alocativas de recursos financeiros novos e mudanças no aparato organizativo de resposta, com efeitos para a continuidade das políticas no pós-emergência, incluindo o desenvolvimento de medicamentos, vacinas e testes. A Emergência em Saúde Pública do Zika Vírus no Brasil foi marcada por limitada institucionalização de aprendizados e estratégias estruturantes, reduzindo oportunidades para a (re)organização das vigilâncias no Sistema Único de Saúde.

In Brazil, abortion is considered a crime under the Criminal Code since 1940. After the Zika virus epidemic (2015-2017) and the consequent appearance of microcephaly in newborns struck South America, the debate on the decriminalization of abortion in the Brazilian society was reignited. Using data obtained from focus groups comprising women of reproductive age across different socioeconomic strata and two Brazilian cities, we investigated the perceptions of the participants on abortion, especially its use during the Zika epidemic. Although legally criminalized, abortion is prevalent among women, as a way to fulfill their reproductive desire. Criminalization puts the health and lives of women at risk, particularly those with less economic and cultural capital. We also discover the role of friends in women’s decision to utilize the procedure. The strong asym-metry of power between men and women contributes to the greater vulnerability of women. The results suggest an urgent need to review the legislation on abortion concerning its criminalization and the option of safer abortion within the scope of the public health service.
