- Detecting dengue fever in children using online Rasch analysis to develop algorithms for parents: An APP development and usability study Fri, 31 Mar 2023 06:00:00 -0400
CONCLUSION: The development of an LR-based APP for the detection of DF in children has been completed. To help patients, family members, and clinicians differentiate DF from other febrile illnesses at an early stage, an 11-item model is proposed for developing the APP.
- Influence of mosquito-borne biological agents on health risks among soldiers and military personnel Fri, 31 Mar 2023 06:00:00 -0400
INTRODUCTION AND OBJECTIVE: Mosquitoes are the most important vector group for humans, and three genera - Aedes, Anopheles and Culex, are of greatest significance in the transmission of pathogens to humans and animals. The geographical expansion of vectors can lead to the spread diseases into new regions. Soldiers exercise in the field, participate in missions, or are stationed in Military Contingents located in different climatic conditions, which is directly related to exposure to...
- Biosynthesis of zinc oxide nanoparticles using Indigofera tinctoria and their efficacy against dengue vector, Aedes aegypti (Diptera: Culicidae) Thu, 30 Mar 2023 06:00:00 -0400
Dengue fever is a viral mosquito borne disease transmitted by day biting mosquito, Aedes aegypti. No medicine has been proven to be effective for the complete cure of dengue and mosquito control remains to be the only effective option. Increased cases of dengue contraction are being enormously reported worldwide every year. Thus, the urge for an effective measure remains a factor of major concern. In the present study, biosynthesized spherical-like structured zinc oxide (ZnO) nanoparticles using...
- Early diagnosis of dengue: Diagnostic utility of the SD BIOLINE Dengue Duo rapid test in Reunion Island Thu, 30 Mar 2023 06:00:00 -0400
CONCLUSIONS/SIGNIFICANCE: These results suggest that the SD Bioline Dengue Duo RDT did not achieve sufficient performance levels to rule in, or discard, an early point of care dengue diagnosis in the emergency department during the 2019 epidemic in Reunion.
- The anti-immune dengue subgenomic flaviviral RNA is present in vesicles in mosquito saliva and is associated with increased infectivity Thu, 30 Mar 2023 06:00:00 -0400
Mosquito transmission of dengue viruses to humans starts with infection of skin resident cells at the biting site. There is great interest in identifying transmission-enhancing factors in mosquito saliva in order to counteract them. Here we report the discovery of high levels of the anti-immune subgenomic flaviviral RNA (sfRNA) in dengue virus 2-infected mosquito saliva. We established that sfRNA is present in saliva using three different methods: northern blot, RT-qPCR and RNA sequencing. We...
- Understanding antibody-dependent enhancement in dengue: Are afucosylated IgG1s a concern? Thu, 30 Mar 2023 06:00:00 -0400
- A Unique Case of Unilateral Oculomotor Nerve Palsy Secondary to Dengue Fever Thu, 30 Mar 2023 06:00:00 -0400
A wide range of ocular complications may arise from the mosquito-borne illness, dengue fever. We report a case of isolated unilateral oculomotor nerve palsy due to complications of dengue fever. A 50-year-old male with serologically confirmed dengue fever presented with a sudden onset of double vision with left eyelid drooping and left eye outward deviation on his day 8 of illness. Ocular examination revealed binocular diplopia with complete left eye ptosis and restriction of all left eye...

- Antibody Immunity to Zika Virus among Young Children in a Flavivirus-Endemic Area in Nicaragua Thu, 30 Mar 2023 06:00:00 -0400
Objective: To understand the dynamics of Zika virus (ZIKV)-specific antibody immunity in children born to mothers in a flavivirus-endemic region during and after the emergence of ZIKV in the Americas. Methods: We performed serologic testing for ZIKV cross-reactive and type-specific IgG in two longitudinal cohorts, which enrolled pregnant women and their children (PW1 and PW2) after the beginning of the ZIKV epidemic in Nicaragua. Quarterly samples from children over their first two years of life...
- Role of the Microbiome in Aedes spp. Vector Competence: What Do We Know? Thu, 30 Mar 2023 06:00:00 -0400
Aedes aegypti and Aedes albopictus are the vectors of important arboviruses: dengue fever, chikungunya, Zika, and yellow fever. Female mosquitoes acquire arboviruses by feeding on the infected host blood, thus being able to transmit it to their offspring. The intrinsic ability of a vector to infect itself and transmit a pathogen is known as vector competence. Several factors influence the susceptibility of these females to be infected by these arboviruses, such as the activation of the innate...
