Zika virus (ZIKV) is an emerging flavivirus, which has caused a widespread outbreak in the Americas. Shortly after its introduction in 2015, a cluster of cases with Guillain-Barré syndrome was detected in Brazil. Herein, we describe two cases from the city of Salvador, who developed ascending paresis after an acute exanthematous illness. The patients were admitted to the intensive care unit with tetraparesis and cranial nerve palsy, which resolved after intravenous administration of human immunoglobulin. Serological evaluation detected IgM-specific ZIKV antibodies. In regions of Zika virus transmission, health-care workers must be aware of the potential severe neurological complications associated with ZIKV infection and be prepared to provide prompt diagnosis, treatment, and supportive care.

Background: Zika virus (ZIKV) continues to circulate in Southeast Asia following the 2015-2016 global epidemic, posing an ongoing risk of importation and disease spread for Singapore, a tropical city-state in the region. The virus remains a threat to pregnant women and their fetuses due to the risk of Congenital Zika Syndrome (CZS). Vaccines currently in development offer hope for reducing ZIKV infections and CZS cases.

One of the most significant bacteriophage technologies is phage display, in which heterologous peptides are exhibited on the virion surface. This work describes the display of λ decorative protein D linked to the E protein domain III of Zika virus (D-ZE), to the GFP protein (D-GFP), or to different domain III epitopes of the E protein (D-TD), exhibited on the surface of an in vitro evolved lambda phage (λ). This phage harbors a gene D deletion and was subjected to directed evolution using Escherichia coli W3110/pD-ZE as background.

Background: Zika virus (ZIKV) infection during pregnancy can lead to congenital Zika syndrome (CZS) and may result in neurodevelopmental alterations in exposed children, with and without CZS. This study aimed to evaluate ZIKV infection during pregnancy as a risk factor for early and long-term adverse outcomes.
Methods: This retrospective-prospective, matched cohort study was conducted in Mato Grosso do Sul, Brazil.

Arboviruses currently are regarded as a major worldwide public health concern. The clinical outcomes associated with this group of viruses may vary from asymptomatic infections to severe forms of haemorrhagic fever characterised by bleeding disorders. Similar to other systemic viral infections, arboviruses can either directly or indirectly affect different parts of the body, such as the urogenital system.

Orthoflaviviruses are positive-sense single-stranded RNA viruses that hijack host proteins to promote their own replication. Zika virus (ZIKV) is infamous among orthoflaviviruses for its association with severe congenital birth defects, notably microcephaly. We previously mapped ZIKV-host protein interactions and identified the interaction between ZIKV non-structural protein 4A (NS4A) and host microcephaly protein ankyrin repeat and LEM domain-containing 2 (ANKLE2).
