Combination of ELISA screening and seroneutralisation tests to expedite Zika virus seroprevalence studiesby Nurtop et al.
The authors of this study propose a strategy allowing implementing efficient and practicable large-scale seroepidemiological studies for Zika Virus (ZIKV).
Human stem cell-derived hepatocyte-like cells support Zika virus replication and provide a relevant model to assess the efficacy of potential antiviralsby Tricot et al.
The authors of this study demonstrate that both human pluripotent stem cell (hPSC)-derived hepatocyte-like cells (HLCs) and the Huh7 hepatoma cell line support the complete ZIKV replication cycle.

A yellow fever–Zika chimeric virus vaccine candidate protects against Zika infection and congenital malformations in miceby Kum et al.
The authors of this study report the engineering of a chimeric virus vaccine candidate (YF-ZIKprM/E) by replacing the antigenic surface glycoproteins and the capsid anchor of YFV-17D with those of a prototypic Asian lineage ZIKV isolate.

Favipiravir inhibits in vitro Usutu virus replication and delays disease progression in an infection model in miceby Guerrero et al.
This study shows that treatment of mice with favipiravir (150 mg/kg/dose, BID, oral gavage) significantly reduced viral load in blood and tissues and significantly delayed virus-induced disease. The USUV mouse model is amenable for assessing the potential in vivo efficacy of (novel) USUV/flavivirus inhibitors.
The authors of this study have identified three major bottlenecks in the implementation of a swift response to the increasing frequency of widespread infectious disease outbreaks: the absence of a timeline for the funding process, delays in regulatory and ethical approval, and the challenging logistics of laboratory support, including diagnostics.
The model provided in this study correctly estimates the number of imported cases and can be easily adapted to other urban areas where Ae. albopictus is the only potential vector present.
Research Models and Tools for the Identification of Antivirals and Therapeutics against Zika Virus Infectionby Alves et al.
This review focuses on the recent advances regarding research models, as well as available experimental tools that can be used for the identification and characterization of potential antiviral targets and therapeutic intervention strategies.
The findings from this study suggest a possible long-term detrimental effect of ZIKV infection on human male fertility that has to be further explored in well-characterized samples from cohort studies conducted in ZIKV-endemic areas.
The findings in this article suggest that the ZIKV epidemic is by and large over within LAC, with incidence projected to be low in most cities in 2018. Local low levels of transmission are probable, but the estimated rate of infection suggests that most cities have a population with high levels of herd immunity.
This study provides key insights into how ZIKV may persist in semen and alter semen parameters, as well as a valuable tool for testing antiviral agents.
Differential transmission of Asian and African Zika virus lineages by Aedes aegypti from New Caledoniaby Calvez et al.
The results of this study demonstrate that Ae. aegypti from New Caledonia can become infected and replicate different ZIKV strains belonging to all lineages. These data emphasize the importance of studying the interaction between vectors and their arboviruses according to each local geographic context.

Exhaustive TORCH Pathogen Diagnostics Corroborate Zika Virus Etiology of Congenital Malformations in Northeastern Brazilby Moreira-Soto et al.
Data from this study support a link between maternal ZIKV infection and congenital malformations and suggest the occurrence of predominantly vector-borne ZIKV transmission in these cases. In addition, some highly prevalent TORCH pathogens may be misinterpreted as representative of ongoing ZIKV activity in the absence of exhaustive diagnostics in northeastern Brazil.
Results from this study indicate a low ZIKV transmission by Ae. aegypti and Ae. polynesiensis tested from the Pacific region. These results were unexpected and suggest the importance of other factors especially the vector density, the mosquito lifespan or the large immunologically naive fraction of the population that may have contributed to the rapid spread of the ZIKV in the Pacific region during the 2013–2017 outbreak.
Re-visiting the evolution, dispersal and epidemiology of Zika virus in Asia. A commentary from the authors.by Pettersson et al.
Pettersson et al provide a short commentary on their research article Re-visiting the evolution, dispersal and epidemiology of Zika virus in Asia published in Emerging Microbes & Infections in May 2018. This work was supported by the European Union’s Horizon 2020 Research and Innovation Programme under ZIKAlliance Grant Agreement no. 734548 and ZikaPLAN Grant Agreement no. 734584.
4 EU-funded Zika consortia met in Marseille during the International Symposium to discuss a common strategy for vaccine developmentby ZIKAlliance
In this study, the authors have traced the phylogenetic history and spatio-temporal dispersal pattern of ZIKV in Asia prior to its explosive emergence in the Pacific region and the Americas.
