Study protocol for the multicentre cohorts of Zika virus infection in pregnant women, infants, and acute clinical cases in Latin America and the Caribbean: the ZIKAlliance consortium

Results of large cohort studies will provide better risk estimates for birth defects and other developmental abnormalities associated with ZIKV infection including possible co-factors for the variability of risk estimates between other countries and regions. Additional outcomes include incidence and transmission estimates of ZIKV during and after pregnancy, characterization of short and long-term clinical course following infection and viral kinetics of ZIKV.

High Zika Virus Seroprevalence in Salvador, Northeastern Brazil Limits the Potential for Further Outbreaks

In this article, authors find that the high burden of Zika virus infection in a northeastern Brazilian metropolis questions the fate of the outbreak due to population protective immunity; that Zika virus infection predominantly affects geographic areas with low socioeconomic status, demonstrating a clear link between poverty and Zika virus infection; and, finally, additional evidence for the link between Zika virus infection and microcephaly.

High Zika Virus Seroprevalence in Salvador, Northeastern Brazil Limits the Potential for Further Outbreaks [Press Release]

A study published this week in mBio demonstrates rapid spread of ZIKV in Salvador, a metropolis in northeastern Brazil representing one of the most affected areas during the American ZIKV outbreak, and infection rates exceeding 60%.

The REDe Guide to Clinical Research Practical Data Quality Monitoring

This guide will set out why quality management and monitoring is important and how it can be easily and practically built into a study.
