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.

This study demonstrates the circulation of ZIKV in Mali and provides evidence of a previously unidentified outbreak that occurred in the late 1990s.

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.

In this study the authors' data provide a convenient and practicable solution to ensure robust differentiation of CHIKV- and MAYV-specific antibodies.

Findings in this study highlight the occurrence of the Fort Sherman virus (FSV) across a geographic range exceeding 7,000 km, surprising genomic conservation across a time span exceeding 50 years, M gene‐based reassortment events, and the existence of multiple animal hosts of FSV.

This study shows that urine ZIKV RT-PCR testing in the acute phase of infection can improve the sensitivity of diagnosis, while testing serum is probably less useful despite more sustained shedding in some cases. Higher sensitivity and specificity serological tests are needed for the diagnosis of patients who seek medical attention after the period of ZIKV detection by RT-PCR and for surveillance purposes in settings of high DENV background infection.

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

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.

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%.

In 2015–2016 in the Recife Metropolitan Region, the authors of this study detected the tail end of a Zika epidemic, which was displaced by a chikungunya epidemic. Few dengue cases were identified despite a high number of official dengue notifications in the area during this period. This study shows here important epidemiological features of these cases.
