This study strengthens the evidence that congenital ZIKV infection, particularly in the first 2 trimesters of pregnancy, is associated with microcephaly and less frequently with other birth defects. The finding of no alternative causes for geographic differences in microcephaly rate lead the authors to hypothesize that the Northeast region of Brazil was disproportionately affected by this Zika outbreak, with 94% of an estimated 8.5 million total cases occurring in this region, suggesting a need for seroprevalence surveys to determine the underlying reason.

Recurrent recent arbovirus infections suggested by serologic data and unspecific symptoms highlight the need for exhaustive virologic testing.

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.

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.

The authors conducted field work in Brazil to sample marsupials, one of the most ancient mammalian lineages, and identified a new HAV, marsupial HAV (MHAV).

Since December 2016, Brazil has experienced an unusually large outbreak of yellow fever (YF). Whether urb a n transmission may contribute to the extent of the outbreak is unclear. The objective of this study was to characterize YF virus (YFV) genomes and to identify spatial patterns to determine thedistribution and origin of YF cases in Minas Gerais, Espírito Santo and Rio de Janeiro, the most affected Brazilian states during the current YFV outbreak.

The authors of this study discuss gaps in the knowledge and the challenges ahead to anticipate, prevent, and control emerging and re-emerging epidemics of arboviruses in Brazil and worldwide.

Results from this study suggest that despite the inter-individual variability in immune responses, the magnitude of the maternal ZIKV-specific neutralizing antibody response may prove useful to corroborate congenital ZIKV infection, contributing to reliable estimates of the manifestation index of ZIKV-associated congenital disease. Further studies will be needed to evaluate the time-course of maternal neutralizing antibody responses to identify whether a high maternal PRNT titer can be used as an early marker of congenital infection aiding potential antiviral intervention strategies.

Challenges of scientific collaboration during an outbreak: the recent experience with Zika in Brazil

Results from this study further indicate that viruses from northeast Brazil were important for the continental spread of ZIKV. Within Brazil, the authors find instances of virus lineage movement from northeast to southeast Brazil; most of these events are dated to the second half of 2014 and led to onwards transmission in Rio de Janeiro and São Paulo states. The authors infer that ZIKV lineages disseminated from northeast Brazil to elsewhere in Central America, the Caribbean, and South America.

The study shows that Culex quinquefasciatus should not be considered a potential vector of ZIKV in Brazil.

The key message from this study is that the large uncertainty around the risk estimate needs to be further investigated because of a) the possible existence of co-factors that are yet to be validated, b) the assumptions that the authors needed to make in the absence of good data for the proportion of women who were infected during pregnancy.

Hosted by University Sao Paulo Medical School at the Centro de Convenções Rebouças ZIKAlliance, the multinational and multidisciplinary consortium coordinated by Inserm, the French National Institute of Health and Medical Research, and  created in response to a Horizon 2020 funding call by the European Commission’s Directorate-General Research and Innovation, has officially started its activities with the kick-off meeting held in Brazil over the 4th and 5th December 2016.

GloPID-R members hosted the “GloPID-R Zika Virus Research Workshop” in Sao Paulo, Brazil on November 30 – December 2, 2016 to facilitate collaboration between members on Zika funded research projects. The workshop’s aim was to identify and establish collaboration and synergies between the research and capacity development projects in support of the Zika virus response in Latin America and the Caribbean funded by GloPID-R members worldwide.
