Purpose Of Review: Although cases of Zika virus disease (ZVD) have declined globally since 2017, new outbreaks have been reported, such as in Asia in 2024. As there is no vaccine or treatment available to date, both vaccines and mAbs neutralizing Zika virus would be of great interest, especially for pregnant women and immunocompromised patients such as those living with HIV. This review focuses on new insights regarding ZVD in the last two years and summarizes the key literature on global epidemiology, transmission, diagnostics, clinical features, preventive measures, and treatment options.
Recent Findings: At the time of writing, ZVD is endemic across tropical and subtropical regions of the world, with the highest risk of infection in Latin America and the Caribbean, but no significant peaks in outbreak activity across endemic regions. There are ongoing efforts to further investigate the clinical and epidemiological long-term sequelae of the large outbreak in the Americas 2015-2018; further refinement of diagnostic tools to improve specificity in view of significant cross-reactivity potential, particularly with dengue virus. Multiple vaccines are in different clinical development stages; however, phase 3 trials are awaiting the next epidemic.
Summary: While there is no current major zika virus outbreak, progress has been made in the epidemiological work-up of clinical-epidemiological data, refinement of diagnostic tools, and mainly preventive (vaccines) rather than curative (drugs) tools.

Compound 13b, a newly identified anthraquinone derivative, has demonstrated potent efficacy against the Zika virus. To explore the bioavailability and pharmacokinetic properties of compound 13b, a robust and sensitive HPLC-MS/MS method was established and verified to determine its plasma concentration in rats. Sample preparation involved protein precipitation using acetonitrile with testosterone as an internal standard.

Studies focused on the epidemiological surveillance of arboviruses that cause potentially zoonotic diseases, such as dengue, Zika, or emerging viruses like West Nile virus (WNV), are critical due to their significant impact on public health. Although research on these infectious agents is increasing in Colombia, regions remain where the presence of zoonotic agents is still unknown. To address this knowledge gap, the present study aimed to investigate the current status of WNV circulation in wildlife in two municipalities of the department of Casanare (El Yopal and Paz de Ariporo) from the Colombian region of Orinoquia.

Zika virus (ZIKV) poses a significant threat due to its association with severe neurological complications, particularly during pregnancy. Although viruses exhibit tropism for neural cells, including astrocytes, the role of these cells in controlling ZIKV replication remains unclear. In this study, we demonstrated that ZIKV induces caspase-1 activation in primary astrocytes despite the absence of classical signs of inflammasome activation.

The fetal origins of neuropsychiatric disorders are poorly understood but have been linked to viral or inflammatory injury of the developing brain. The fetal white matter is particularly susceptible to injury as myelination, axonal growth, and deep white matter tracts become established. We have used the pigtail macaque (Macaca nemestrina) to study the maternal and fetal effects of influenza A virus (FLUAV) and Zika virus (ZIKV) infection during pregnancy, in cohorts with different time intervals between inoculation and delivery.

Some viruses counter host-cell efforts to digest invading viral RNA by using special structures resistant to host RNases, known as exoribonuclease-resistant RNAs (xrRNAs). xrRNAs typically form an unusual fold with the 5'-end threaded through a ring consisting of a multihelix junction closed by a pseudoknot. By using single-molecule force spectroscopy (SMFS), we previously showed that a Zika virus xrRNA is extremely rigid mechanically, withstanding very high forces, and that this mechanical resistance-not simply the knot-like fold topology-is essential for RNase resistance.
