Dengue infection may be asymptomatic and may produce the typical symptoms of a benign illness or serious hemorrhagic and often fatal symptoms. Asymptomatic cases are statistically relevant and quite variable depending on the geographic area under study. However, there are no reports of asymptomatic population infected by the dengue virus in Misiones. In this study, 288 samples were analyzed, and the IgG anti dengue antibodies detected accounted for 6.6% of cases, while 89% corresponded to individuals who lived with people diagnosed or suspected of having contracted dengue, p= <0.001.

Role of extracellular vesicles in the pathogenesis of mosquito-borne flaviviruses that impact public health.
J Biomed Sci

Mosquito-borne flaviviruses represent a public health challenge due to the high-rate endemic infections, severe clinical outcomes, and the potential risk of emerging global outbreaks. Flavivirus disease pathogenesis converges on cellular factors from vectors and hosts, and their interactions are still unclear. Exosomes and microparticles are extracellular vesicles released from cells that mediate the intercellular communication necessary for maintaining homeostasis; however, they have been shown to be involved in disease establishment and progression.

At the 2023 Global Vaccine and Immunization Research Forum (GVIRF), researchers from around the world gathered in the Republic of Korea to discuss advances and opportunities in vaccines and immunization. Many stakeholders are applying the lessons of Covid-19 to future emergencies, by advancing early-stage development of prototype vaccines to accelerate response to the next emerging infectious disease, and by building regional vaccine research, development, and manufacturing capacity to speed equitable access to vaccines in the next emergency. Recent vaccine licensures include: respiratory syncytial virus vaccines, both for the elderly and to protect infants through maternal immunization; a new dengue virus vaccine; and licensure of Covid-19 vaccines previously marketed under emergency use authorizations.

This study details a genomics-based approach for the early detection of mosquito-borne pathogens, marked by Uruguay's first ever complete genomic sequencing of Dengue Virus type I genotypes I and V. This pioneering effort has facilitated the prompt identification of these genotypes within the country, enabling Uruguayan public health authorities to develop timely and effective response strategies. Further integrated into this approach is a climate-driven suitability measure, closely associated with Dengue case reports and indicative of the local climate's role in the virus's transmission in the country within the changing climate context.

Introduction: Dengue, a prevalent mosquito-borne viral disease in tropical regions, is influenced by environmental factors such as rainfall, temperature, and urbanization. This study aims to assess the effects of microclimate, vegetation, and Aedes species distribution on dengue transmission in distinct hotspot and non-hotspot locations.
Methods: This cohort study was conducted in two sites within Selangor, Malaysia: a recurrent dengue hotspot and a non-dengue hotspot.
Dengue virus IgG and neutralizing antibody titers measured with standard and mature viruses are protective.

The standard dengue virus (DENV) neutralization assay inconsistently predicts dengue protection. We compare how IgG ELISA, envelope domain III (EDIII), or non-structural protein 1 (NS1) binding antibodies, and titers from plaque reduction neutralization tests (PRNTs) using standard and mature viruses are associated with dengue. The ELISA measures IgG antibodies that bind to inactivated DENV1-4.
