In 2016, four clusters of local mosquitoborne Zika virus transmission were identified in Miami-Dade County, Florida, USA, generating "red zones" (areas into which pregnant women were advised against traveling). The Miami-Dade County Mosquito Control Division initiated intensive control activities, including property inspections, community education, and handheld sprayer applications of larvicides and adulticides. For the first time, the Mosquito Control Division used a combination of areawide ultralow-volume adulticide and low-volume larvicide spraying to effectively control Aedes aegypti mosquitoes, the primary Zika virus vector within the county. The number of mosquitoes rapidly decreased, and Zika virus transmission was interrupted within the red zones immediately after the combination of adulticide and larvicide spraying.

Over the last decade, mRNA vaccines development has shown significant advancement, particularly during the COVID-19 pandemic. This comprehensive review examines the efficacy of pivotal vaccines against emerging COVID-19 variants and strategies for enhancing vaccine effectiveness. It also explores the versatility of mRNA technology in addressing other infectious diseases such as influenza, respiratory syncytial virus, HIV, cytomegalovirus, Ebola, Zika, Rabies, and Nipah viruses.

Among flaviviruses, Zika virus (ZIKV) is the only arbovirus officially recognized as a teratogenic agent, as a consequence of its ability to infect and cross the placental barrier causing congenital malformation in the fetus. While many studies have focused on understanding ZIKV pathogenesis during pregnancy, the viral mechanisms affecting fetal development remain largely unclear. In this study, we investigated ZIKV virulence in placental trophoblasts, using viruses with distinct lipid profiles.

The Zika virus (ZIKV), an arbovirus within the Flavivirus genus, is associated with severe neurological complications, including Guillain-Barré syndrome in affected individuals and microcephaly in infants born to infected mothers. With no approved vaccines or antiviral treatments available, there is an urgent need for effective therapeutic options. This study aimed to identify new natural compounds with inhibitory potential against the NS2B-NS3 protease (PDB ID: 5LC0), an essential enzyme in viral replication.

A large population in the world lives in tropical and subtropical regions, showing a high risk of Zika viral infection which leads to a situation of global health emergency and demands extensive research to create effective antiviral medicines. Herein, we introduce the design of a new derivatized trans-stilbene molecule to investigate the inhibition of Zika virus entry into the host cell by molecular docking approach. The synthesized compound has been characterized by different analytical techniques such as FTIR, H NMR,C NMR and UV-visible spectroscopy as well as Mass spectrometry (MS).
