Purpose Of Review: Complex environmental factors and human intervention influence the spread of arthropod vectors and the cycle of transmission of arboviruses. The spectrum of clinical manifestations is diverse, ranging from serious presentations like viral hemorrhagic fever (e.g., dengue, yellow fever, rift valley fever) or shock syndromes (e.g., dengue virus) to organ-specific illness like meningoencephalitis.
Recent Findings: A spectrum of clinical neurologic syndromes with potential acute devastating consequences or long-term sequelae may result from some arboviral infections.
Summary: In this review, we describe some of the most frequent and emerging neuro-invasive arboviral infections, spectrum of neurologic disorders including encephalitis, meningitis, myelitis or poliomyelitis, acute demyelinating encephalomyelitis, Guillain-Barré syndrome, and ocular syndromes.

Objectives: Arboviruses pose a significant global health challenge. This study investigated the seroprevalence of major human arboviral infections, including yellow fever (YFV), dengue (DENV), Crimean-Congo hemorrhagic fever (CCHF), Rift Valley fever (RVF), West Nile virus (WNV), and chikungunya (CHIK), in Darfur region from September to December 2018. ELISA-IgM was used to detect antibodies.

Dengue-related ocular complications were considered rare, but recent evidence points to a broader spectrum of manifestations, including uveitis. This study utilized the Taiwan National Health Insurance Research Database (NHIRD) to investigate the incidence of uveitis in dengue patients, aiming to fill this research gap. This population-based, retrospective cohort study utilized the Taiwan National Health Insurance Research Database (NHIRD) and included patients with and without Dengue fever.

During the past decade (and beyond), neurologists have become aware of the emergence, persistence, and consequences of some familiar and new infections affecting the nervous system. Even among the familiar CNS infections, such as herpes virus, polyoma virus/JC, influenza, arbovirus, and hepatitis, challenges remain in developing effective antiviral treatments and treatments of postinfection sequelae. With the changing environment and increased global travel, arthropod vectors that mediate zoonotic disease transmission have spread unfamiliar viruses such as West Nile virus, dengue, chikungunya, equine encephalitis, and Zika, among others.

Viruses transmitted by mosquitoes threaten the health of millions of people worldwide. There is an urgent need for new tools for personal protection to ensure that vulnerable individuals are protected from infectious bites when outdoors. Here, we test the efficacy of wash-in and spray-on repellents against Aedes aegypti.

Arthropod-borne viruses (arboviruses) are transmitted to humans by arthropod vectors and pose a serious threat to global public health. Neurotropic arboviruses including Sindbis virus (SINV) persistently infect the central nervous system (CNS) of vector insects without causing notable pathological changes or affecting their behavior or lifespan. However, the mechanisms by which vector insects evade these viral infections in the brains are poorly understood.
