*Portuguese content* Com objetivo de avaliar como as famílias dessas crianças foram impactadas, a pesquisa Impactos econômicos e sociais do vírus Zika foi realizada no IFF-Fiocruz, hospital público federal situado no Rio de Janeiro, que atua em ensino, pesquisa e atendimento a mulheres, crianças e adolescentes. Foram entrevistadas cuidadoras e cuidadores (mães, pais e familiares) que acompanhavam crianças com ou sem SCZ para atendimento no IFF no período de maio de 2017 a janeiro de 2018. Foram utilizados questionários que buscavam conhecer as características socioeconômicas, uso dos serviços de saúde e os custos das famílias no período de um ano. Além disso, também foram conduzidas entrevistas sem questionário sobre temas como gestação, cuidado e trabalho.
Pregnant Women Infected with Zika Virus Show Higher Viral Load and Immunoregulatory Cytokines Profile with CXCL10 Increaseby Camacho-Zavala et al.
Results in this paper reveal that the anti-inflammatory response in pregnant women infected with ZIKA is characterized by high CXCL10, a cytokine correlated with congenital malformations.
Zika virus infection in pregnancy: a protocol for the joint analysis of the prospective cohort studies of the ZIKAlliance, ZikaPLAN and ZIKAction consortiaby Ades et al.
This article provides a protocol for the joint analysis of the prospective cohort studies of the ZIKAlliance, ZikaPLAN and ZIKAction consortia.
This paper finds that Ae. aegypti vector competence for ZIKV from macaques is low, likely to be due to low viral load and the short duration of ZIKV viremia in primates suitable for infecting susceptible mosquitoes.
Influence of Temperature on the Life-Cycle Dynamics of Aedes albopictus Population Established at Temperate Latitudes: A Laboratory Experimentby Marini et al.
Findings in this article highlight the ability of Aedes albopictus to quickly adapt to colder environments and provide new important insights on the bionomics of this species at temperate latitudes.
Zika virus transmission by Brazilian Aedes aegypti and Aedes albopictus is virus dose and temperature-dependentby Chouin-Carneiro et al.
Results indicate that Brazilian populations of Ae. aegypti exhibit a much higher transmission potential for ZIKV than Ae. albopictus.
Contrasted transmission efficiency of Zika virus strains by mosquito species Aedes aegypti, Aedes albopictus and Culex quinquefasciatus from Reunion Islandby Gomard et al.
Our results show that both Ae. albopictus and Ae. aegypti, from Reunion Island, are more likely to be competent for ZIKV in contrast to Cx. quinquefasciatus which appeared refractory to all tested ZIKV strains. This improves our understanding of the role of mosquito species in the risk of the ZIKV emergence on Reunion Island.
Vector Competence of Aedes aegypti, Aedes albopictus and Culex quinquefasciatus from Brazil and New Caledonia for Three Zika Virus Lineagesby Fernandes et al.
Viral surveillance and mosquito control measures must be strengthened to avoid the spread of new ZIKV lineages and minimize the transmission of viruses currently circulating.
This is the first report of mosquitoes infected with CHIKV in Iran. The high-throughput screening method here presented can be proposed as a novel epidemiological surveillance tool to identify circulating arboviruses and to support preparedness to an epidemic in animals and humans.
In this study, researchers provide the first demonstration of ZIKV accumulation in the saliva of Cx. pipiens upon forced infection. Nevertheless, they consider Cx. pipiens as a highly inefficient vector for ZIKV.
Researchers have found that ZIKV immunity might be shorter-lived than previously thought, which may contribute to local ZIKV resurgence once individual immune responses wane sufficiently to reduce community protective immunity in addition to birth and migration.
These findings highlight the need to strengthen MAYV surveillance in the region and showcase how modeling can improve interpretation of cross-reacting assays.
The V410L knockdown resistance mutation occurs in island and continental populations of Aedes aegypti in West and Central Africaby Ayres et al.
These results suggest that populations carrying the same kdr mutations may respond differently to the same insecticide, stressing the need for complementary studies when assessing the impact of kdr resistance mechanisms in the outcome of insecticide-based control strategies.
This study demonstrates the circulation of ZIKV in Mali and provides evidence of a previously unidentified outbreak that occurred in the late 1990s.
The invasive Asian bush mosquito Aedes japonicus found in the Netherlands can experimentally transmit Zika virus and Usutu virusby Abbo et al.
Given that Ae. japonicus can experimentally transmit arthropod-borne viruses (arboviruses) like ZIKV and USUV and is currently expanding its territories, we should consider this mosquito as a potential vector for arboviral diseases in Europe.
This analysis confirms the potential of Ae. albopictus as a bridge vector based on its colonization of natural breeding sites in newly invaded areas, its opportunistic feeding behaviour together with the preference for human blood, and the competence to transmit 14 arboviruses.
Survey on Non-Human Primates & Mosquitoes Does not Provide Evidences of Spillover/Spillback between the Urban & Sylvatic Cycles of YFV & ZIKV Following Severe Outbreaks in Southeast Brazilby de Abreu et al.
The present study showed that there is no evidence that the ZIKV established an independent sylvatic cycle in the state of Rio de Janeiro, and provided new evidence that there was no urban transmission of Yellow Fever Virus in southeast Brazil during the current outbreak.
Mapping the response to Zika, a public health emergency, demonstrated a clear pattern of the participation of countries in the scientific advances. The pattern of knowledge production found in this study represented varying country perspectives, research capacity and interests based first on their level of exposure to the epidemic and second on their financial positions regarding science.
Optimisation and field validation of odour-baited traps for surveillance of Aedes aegypti adults in Paramaribo, Surinameby Visser et al.
This study demonstrates that the BG-Sentinel trap baited with the MB5 blend and CO2 outperforms the current golden standard (BG-Sentinel trap with BG-Lure) for monitoring Ae. aegypti females and males, in both laboratory and field experiments. The BG-Bowl baited with the MB5 blend is a good candidate for home use. Finally, the results show that CO2 is an indispensable component of the attractive blend.
Building on the UN’s Sustainable Development Goals commitment to “leave no one behind” and the recent championing of a need for a people-centered approach to epidemic preparedness and response, the authors call for more evidence that can support policy recommendations and advocacy efforts for gender-mainstreamed arbovirus control programs in Latin America.
