Você conhece os impactos do vírus Zika sobre as famílias?
by Márcia Pinto et al.*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 Increase
by 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.
This article provides a protocol for the joint analysis of the prospective cohort studies of the ZIKAlliance, ZikaPLAN and ZIKAction consortia.
Low Aedes aegypti Vector Competence for Zika Virus from Viremic Rhesus Macaques
by Fernandes et al.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 Experiment
by 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-dependent
by Chouin-Carneiro et al.Results indicate that Brazilian populations of Ae. aegypti exhibit a much higher transmission potential for ZIKV than Ae. albopictus.
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 Lineages
by 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.
Detection of arboviruses in mosquitoes: Evidence of circulation of chikungunya virus in Iran
by Bakhshi et al.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.
Forced Zika Virus Infection of Culex pipiens Leads to Limited Virus Accumulation in Mosquito Saliva
by Abbo et al.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.
Rapid decline of Zika virus NS1 antigen-specific antibody responses, northeastern Brazil
by Moreira‑Soto et al.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 Africa
by 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.
Zika Virus Circulation in Mali
by Diarra et al.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 virus
by 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.
A Systematic Review: Is Aedes albopictus an Efficient Bridge Vector for Zoonotic Arboviruses?
by Pereira dos Santos et al.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.
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.
The global scientific research response to the public health emergency of Zika virus infection
by de Oliveira et al.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, Suriname
by 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.
Gender mainstreaming as a pathway for sustainable arbovirus control in Latin America
by Wenham et al.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.
